2 INTRODUCTION The Smart CIATControl is a centralised management and control system for cooling and heating equipment designed for use in the healthcare, hotel, office and administration sectors. In addition to managing all comfort units, production units and air handling units, the Smart CIATControl enables optimised management of occupant comfort throughout the building while saving energy and reducing customer energy bills. The Smart CIATControl is a fully autonomous system that enables operators to fine tune all settings in order to meet the needs of the building's occupants. Its touch screen enables easy, intuitive navigation of the various menus. The "systems" functions, most of which are CIAT-patented, can be easily adjusted. The Smart CIATControl has been developed as part of an environmentally responsible policy in full compliance with current standards (RT2012, etc.). 3 EQUIPMENT ACCESS The Smart CIATControl has 2 separate access levels for different types of use:

• Supervision access: o Target: operator/occupants o Functions:

Accessing the system's equipment Displaying the building's tree structure (zones, rooms) Setting the weekly time schedule/calendar Adjusting the setpoints Setting the system functions Accessing operation curves Accessing events (real time and historic) "Secondary" settings (date/time, alert email recipients, network cards, etc.)

• Configurator access:

o Target: CIAT technician/operator o Functions:

Equipment commissioning Repartitioning Adding/removing equipment Setting manufacturer/owner parameters Configuring the BACnet server (if option included)

These access levels are restricted to certain types of user. For more information, refer to the "Access levels" paragraph. It is possible to switch from one access level to another once the user has been identified. 4 HOME PAGE The Smart CIATControl home page is split into 2 sections:

• A top section consisting of: o Access to the system settings o Access to the events (real time and historic) o An identification zone o Access to the tasks in progress o The system date and time o Navigation buttons (previous, home, next) o A breadcrumb trail showing the location in the building and in the Smart CIATControl menus

o Access to the auxiliary equipment

• A central section containing (depending on the equipment controlled by the Smart CIATControl): o 1 "Production units" box o 1 "Comfort units" box o 1 "Air handling units" box o 1 "Building" box

Smart CIATControl home page

The home page is a control panel that shows essential information for all the equipment controlled by the Smart CIATControl. If there are several items of the same type of equipment, they will be classified by family under the following headings:

- Air handling units - Production units - Air handling units

If there is only one item of equipment per family, the equipment name will be directly displayed on the box concerned (e.g. Floway, Aquaciat 2 ILD, etc.).

NA 14.56 A

©2014 CIAT

User guide NA 14.56 A [5] V03.2014

The information for each machine family is displayed on each box:

- Air handling units o the percentage of fresh air (measurement) o the percentage of heat recovery for the Floway = dual-flow unit (calculation)

- Production units o The operating percentage (calculation) o The instantaneous electrical power if one or more electric meters are present on the machines

(measurement) - Comfort units

o The cooling demand percentage o The heating demand percentage

- Building: o The outdoor temperature if at least one production unit is installed o The highest and lowest temperature measured in the building

Note: If several machines per family are present, the information displayed will be the average information based on all the machines. 5 ACCESSING YOUR BUILDING The Smart CIATControl allows you to access the building and the different spaces defined during system start-up. To make it easier to adjust the equipment controlled by the Smart CIATControl, the building is split into "rooms" and "zones". 5.1 DEFINITION OF A ROOM

A room is a physical location such as an office, mechanical room, conference room or lobby. 5.2 DEFINITION OF A ZONE

A zone corresponds to a group of rooms; it generally consists of the entire floor of a building. From the home page, you can view the building's entire system, which consists of comfort units, one or more production units, one or more air handling units and auxiliary equipment (extractors, etc.). Note: Any equipment not controlled by the Smart CIATControl will not be accessible. 6 ACCESSING YOUR BUILDING'S ROOMS AND ZONES To access your building's rooms, press the "Unités de confort" (Comfort units) box on the home page. Press it once to access all the zones in your building.

7.4 AUXILIARY EQUIPMENT

Auxiliary equipment is equipment from manufacturers other than CIAT, and is used to provide secondary functions (HVAC or otherwise) in the building. It is usually non-communicating equipment, or equipment that uses communication protocols which are incompatible with CIAT equipment. Auxiliary equipment is connected to CIAT input/output modules via on/off contacts. These I/O modules then control the following types of equipment:

• Exhaust fan • Lighting circuit • Automatic lubrication • Non-CIAT heat pump • Non-CIAT air handling unit • Etc.

Each item of controlled equipment is assigned to a 1 input/1 output pair. Example:

• Output 1: exhaust fan control • Input 1: operating feedback or fault return for exhaust fan

Each input/output pair has the following control functions:

• On/off time schedule • Operation override

The auxiliary equipment can be accessed by clicking on the "Bâtiment" (Building) box then on "Modules auxiliaires" (Auxiliary modules), then selecting the desired equipment. Its current operating status can then be viewed.

8 ESSENTIAL FUNCTIONS

8.1 EQUIPMENT SETTINGS

Certain settings can be made for each type of equipment (comfort units, production units, air handling units and auxiliaries). To change a setting, simply press the "Réglages" (Settings) button for the relevant room or zone or on the "Unités de confort" (Comfort units), "Unités de production" (Production units), "Unités de traitement d’air" (Air handling units) or "Auxiliaires" (Auxiliaries) box.

The temperature range of the comfort units may be set at a number of levels:

- By room (e.g. comfort temperature set to 23°C for office B01) - By zone: the settings will be the same in all the rooms in the zone. Any settings made beforehand to each

room will be overridden. - By building: the settings will be the same in all the zones and thus all the rooms. Any settings made

beforehand to each room or zone will be overridden. The settings for the other equipment can also be entered either per individual machine or for all the machines, by clicking on the "Settings" button for the desired box. Comfort unit settings:

A time schedule for each day of the week can be set for each level in the building and each item of equipment:

- By room - By zone: the settings will be the same in all the rooms in the zone. Any settings made beforehand to each

room will be overridden. - By building: the settings will be the same in all the zones and thus all the rooms. Any settings made

beforehand to each room or zone will be overridden. - For the production units, air handling units or each item of auxiliary equipment.

To set a time schedule, simply press the "Programme" button on the relevant room or zone, or on the "Comfort units", "Production units", "Air handling units" or "Auxiliaries" box. The complete schedule for a week is displayed when the time schedule setting is accessed.

Time schedule over 1 week

To set a time schedule:

- select a period by clicking on the relevant day and the period to be edited - next, click on "Add" to create a new period - select the date and time by scrolling downwards through the setting wheels - confirm

NA 14.56 A

Setting a period

To apply the same setting to several days of the week, use the copy/paste function. To do this:

- select a day to be copied by clicking on the name of the day - click on "Duplicate" - select the days on which the schedule will be applied - confirm

Duplicating days

Note: Each period can be modified or deleted. The setting principle for the time schedule applies to all types of equipment; only the operating modes may vary depending on the modes authorised on each type of machine.

8.3 OVERRIDE

The time schedule for each level in the building and each equipment type may be overridden. The override will last until it is manually turned off. The following levels may be overridden:

- By room - By zone: the time schedule for all the rooms in the zone will be suspended - By building: the time schedule for all the zones and thus all the rooms will be suspended. - For the production unit, air handling unit or for each item of auxiliary equipment.

To override, simply press the "Dérogation" (Override) button for the relevant room or zone or on the relevant "Comfort units", "Production units", "Air handling units" or "Auxiliary modules" box. Example of overriding the time schedule for comfort units:

User guide NA 14.56 A [21] V03.2014

Overriding the time schedule

When an override is active, a hand is displayed in the status bar for the room, zone, machine, etc. to indicate that the time schedule has been suspended.

To cancel an override, simply press the "Override" button again; the Smart CIATControl will then give the option to cancel the active override. Note: The operating mode to be overridden depends on the type of machine. 8.4 CALENDAR

The calendar allows special business and non-business days or periods to be set. Normal operating modes are overridden on special business or non-business days or periods. The time schedule is therefore no longer active throughout this period, and overrides are not applied. To use this function, click on "Add" and define a start date, an end date and the operating mode for each type of equipment. It is also possible to define annual periods (e.g. CHRISTMAS) to avoid the need to redefine the same period every year.

User guide NA 14.56 A [22] V03.2014

Adding a period

For comfort units, a customised selection can be made in order to individually define each room concerned, avoiding the need to deactivate an entire zone when only a few rooms the zone are affected by the closure/absence of occupants.* *Note: the customisation function will be available in 2015.

When a period is active, a "calendar" is displayed in the status bar for the room, zone or machine. The override and the time schedule are then inactive. When the period has been added, a period is also added to the calendar's overview screen.

It is also possible to modify or delete a special period by selecting the period to be modified and clicking on the "Modify" (Modify) or "Supprimer" (Delete) button. You will be asked to confirm your choice. All the periods set are sorted in chronological order. Note: once a period is over, excluding annual periods, it will automatically be deleted from the list.

8.5 EVENTS

The Smart CIATControl features a tool for locating current events. Events are divided into 4 categories:

• Alarms: major event that shuts down the equipment

• Faults: minor event that may shut down the equipment

• Drifts: preventive maintenance event

• Communication errors The events are displayed in real time and are also logged for later consultation (e.g. for in-depth diagnosis on machine faults, checking the event sequence, etc.). Events are saved for at least a year. The summary table shows the events log for the current month*. *Note: the log export function will be available in 2015. The following is displayed for each event:

- The machine that signalled an event - The exact name of the event - The location (zone/room for a comfort unit) or the name of the machine - The time of occurrence or disappearance

View of active events

If an event is active, a notification appears on the bell in the top bar indicating the number of active events in real time.

Example of notification for a zone

In addition to this display summary, three icons may be displayed for the room, the zone and the type of equipment concerned, in order to indicate the location in the building and the criticality level of the event. E.g.: The Ground floor > Room 1 > V3000_0.1.1 equipment has an open window switch. This will appear on the "Comfort units" box, the "Ground floor" zone and "Room 1". 9 SYSTEM FUNCTIONS The Smart CIATControl has advanced "system" functions to enable energy savings while guaranteeing optimal comfort for the building's occupants. The system functions can be activated if the necessary equipment is present on the installation and controlled by the Smart CIATControl. Equipment which is essential for activating the function is shown in red.

9.1 WATER LAW

The water law is a standard function on the controllers of CIAT production units. The Smart CIATControl can be used to activate the function remotely and set the various parameters linked to the function. This regulation is used to alter the production unit's setpoint based on the outdoor temperature, for heating and/or cooling. Cooling example:

0

2

4

6

8

10

12

20 25 30 35

Consigne froid (°C)

If the outdoor temperature rises, the production unit's setpoint decreases to compensate for the significant rise in the outdoor temperature. For heating, the effect is reversed, with the setpoint increasing proportionally to the decrease in the outdoor temperature. Note: for more details, please refer to the production unit manual.

9.2 OPTIMAL’WATER

The Optimal Water® function is a "system" function patented by CIAT and used to optimise the water loop temperature based on the building requirements. The outdoor temperature is also taken into account to provide additional compensation to the self-adjustment of the water loop temperature in case of adverse weather.

Température extérieure (°C) Consigne froid (°C)

In the above example, the production unit's setpoint varies from 5°C at the start of the occupancy period to 12°C (maximum adjustable threshold) in the middle of the day, then the temperature decreases in the afternoon to compensate for variations in the outdoor temperature and to meet the internal requirements of the building. During an unoccupied period, the setpoint switches to an "unoccupied setpoint" of 15°C. This varies until the maximum authorised threshold is reached during an unoccupied period (18°C), given that the cooling demand is very low during this period.

User guide NA 14.56 A [27] V03.2014

Descriptions of the Optimal’Water function settings

- Activating the function on water loop 1 o The Optimal'Water function can be authorised or inhibited for each water loop

- Occupancy – Optimisation coefficient:

o This coefficient is used to set the desired degree of optimisation using a simple cursor. The value can be adjusted between 0 and 100%, with 0% corresponding to maximum optimisation of occupant acoustic comfort and 100% maximum optimisation of the energy consumption level, thereby degrading acoustic comfort.

- Authorised positive shift:

o Maximum authorised shift value for adjusting the production unit setpoint. o This shift is added to the temperature setpoint set on the production unit (e.g.: 15°C + 5°C = 20°C

maximum. Optimal’Water can adjust the setpoint up to a maximum of 20°C). The greater the shift, the greater the savings. (Note: be aware of the resulting water temperature/power compromise on the comfort units and the ability to maintain the temperature in the building)

- Authorised negative shift:

o Minimum authorised shift value for adjusting the production unit setpoint. o This shift is added to the temperature setpoint set on the production unit (e.g.: 15°C - 5°C = 10°C

maximum. Optimal’Water can adjust the setpoint up to a maximum of 10°C). The greater the shift, the greater the savings.

Note: These settings are available in occupied and unoccupied mode. Reference rooms can be defined in order to precisely calculate the new setpoint to be applied to the production unit. These rooms are used to measure the building requirements, and the others are not taken into account by the Optimal’Water function. This function will be available in 2014. 9.3 OPTIMAL’START & OPTIMAL’STOP

Optimal’Start: For a global or individual time schedule, only office occupancy is generally configured. To ensure a comfortable temperature when the occupants arrive, the production and comfort units must be started up in advance. This advance period is often defined arbitrarily for the entire building. Optimal’Start is used to autonomously determine the time required to bring each office to the desired temperature. If the production unit is controlled by Smart CIATControl, it will also be started in advance to bring the water loop to the desired temperature. This adjustment is made per water loop, i.e. for up to 3 production units. In the event of adverse weather conditions, Optimal’Start will also adjust the advance start-up times based on the outdoor temperature. In the above example, the production unit is started approximately 1 hour earlier in order to bring the water loop to the desired temperature (see yellow box).

For comfort units, the advance start-up of the production unit, which brings the water loop to the desired temperature, allows the comfort units to start heating (or cooling, depending on the season) in advance room by room. In this example, the comfort unit is started up 30 minutes before the occupancy period (see purple box) to bring the office to the desired temperature. The setpoint is reached (set to 21°C) at 8 am. Optimal’Stop: The Optimal’Stop "system" function is a function that enables considerable energy savings. It uses the building's inertia to stop production in advance, while maintaining optimal occupant comfort. This inertia calculation is made for each office every day, in order to take into account the current weather conditions.

In the above example, production is stopped approximately 1 hour before the end of the occupancy period (see yellow box). The temperature is reduced by approximately 1°C (adjustable threshold). In this office, the comfort unit is stopped 1 hour earlier (see purple box)

Optimal’Start and Optimal’Stop function settings

Descriptions of the Optimal’Start and Optimal’Stop function settings:

- Activating the function on water loop 1: o The Optimal’Start and Optimal’Stop functions can be authorised or inhibited for each water loop

- Maximum length of the advance start-up period:

o Used by Optimal’Start, it allows the advance production start-up period to be limited. If the building suffers from significant losses, the authorised advance start-up period should ideally be increased to ensure occupant comfort. This setting will result in lower energy savings.

- Maximum length of the advance stoppage period:

o Used by Optimal’Stop, it allows the advance production stoppage period to be limited. If the building suffers from significant losses, the authorised advance stoppage period should ideally be reduced to ensure occupant comfort. This setting will result in lower energy savings.

- Outdoor temperature threshold for activating the very cold coefficient + coefficient grand froid o These settings, which are used by Optimal’Start and Optimal’Stop, enable the outdoor temperature to

be taken into account in order to calculate the advance start-up and stoppage periods. A compensating period is also added to the period calculated for each room.

Note: these settings are available in both heating and cooling mode.

9.4 CHANGEOVER

The "Changeover" function is used to manually or automatically switch production between heating and cooling. There are 3 types of changeover:

• Manual changeover:

The operator can manually force an operating mode (heating/cooling). The operator can also choose to send an email to specified recipients (see Email alerts section) to notify them of a heating or air conditioning changeover.

NA 14.56 A

User guide NA 14.56 A [31] V03.2014

• Automatic changeover: In this case, the changeover is automatic based on the comfort unit requirements. Changeover thresholds must be set to enable this function. The operator can also limit the number of changeovers authorised per day, as well as the minimum time between 2 changeovers. As with the manual changeover, an email can be sent to notify those overseeing the installation of a change to the operating mode.

NA 14.56 A

User guide NA 14.56 A [32] V03.2014

• Annual changeover:

This solution involves setting a date for the changeover from one operating mode to another. The Smart CIATControl can send an email X days in advance to notify maintenance personnel of the changeover.

Note: Changeover is a function that enables switching between heating and cooling per water loop. The requirements may vary between water loops depending on their use. Note that, from 2015, it will also be possible to define reference rooms in order to assess requirements in offices. 9.5 FRESH NIGHT

The "Fresh night" function is a standard function on the air handling units which enables the use of outdoor air during the night to cool the building, mainly in summer. This function is used to limit requirements at the start of the day, thereby reducing the operation of the production units. The Smart CIATControl can be used to activate the function remotely on the handling units. When the outdoor temperature is low enough to cool the building, the air handling units are started up. Note: this function will be available in 2014

9.6 DEGRADED MODE

In the event of a fault on the production unit, degraded mode allows all of the comfort units on the affected water loop to be switched to frost protection mode. Switching the equipment to frost protection mode prevents the comfort units from switching to maximum speed in order to compensate for an excessively low temperature on the water loop. If the comfort units have electric heaters, they will be kept in occupation mode. The operating percentage of the electric heaters can be adjusted to prevent the comfort units from using the electric heaters at 100% throughout the building in degraded mode.
