Connections The device is connected to the indoor unit via the CN06 socket on the indoor PCB and the indoor units supply terminals as illustrated.

Limitations

It is important to note that when an RBC-IT3-PE interface is used the standard 24hour timer functions within the Toshiba remote must not be selected to avoid conflict in switching commands. The remote controller on/off button will be overridden whenever an interface is connected to socket CN06, regardless of whether the RBC-IT3–PE is in use or not. All other functions of the remote controller remain unaffected. It is recommended that the power supply (230v.a.c.) be taken from the respective indoor unit, as indicated on the wiring diagram. The field sourced time-switch may be located in any area. The a/c system will start when terminal 1 of the interface is energised and will override the remote controller on/off functions. Due to the logic used, it is recommended that a minimum switching interval of 30 seconds be adopted. When first energised, it may be noticed that the indoor unit starts briefly and then stops, this is normal and does not indicate a fault with the system.

5.2 RBC-CC163TLE2 ON/OFF Controller

Description

The on/off controller is a product that is capable of operating 16 indoor units from a single location. The device consists of 16 individual on/off buttons, which allows any connected units to be enabled or disabled via a single button operation. It is also possible to enable or disable all of the connected units via single button operation.

Application The device is ideally suited to locations where it may be necessary to remotely enable or disable indoor units. An example of this would be a hotel reception desk, where the receptionist may wish to enable a customer’s room air conditioning during the check-in process or disable it on the departure of a customer. Each of the on/off buttons has a label facility and again using the example of a hotel installation, the buttons could be labeled with a room number. For larger installations up to 4 controllers could be installed on one network, thus allowing 64 master indoor units to be controlled from one location. The device also has the facility for interfacing time clock control, remote switching, remote run signal and remote fault indication from a set of auxiliary contacts.

Connections

The controller requires a 240 Volt single phase 3 Amp power supply, which connects directly to the mains input terminals on the rear of the device.

36

The two-core network cable should be screened and have a minimum cross-sectional area of 1.5mm for networks of up to 1000 meters. This should be increased to 2.5mm for networks of 1000 to 2000 meters total length. The network cable terminates at the U1/U3 and U2/U4 connections on the rear of the device.

Terminals A1, A2 and A3 are used to remotely operate all of the connected indoor units. The indoor units can be enabled with a pulse voltage of 24 Volts applied for 0.5 seconds between terminals A1-A3 and disabled by applying the same voltage between terminals A2-A3. Terminals B1, B2 and B3 provide dry contact outputs for connection to other systems. A relay contact will close between B3 and B1 indicating system operation and B3 and B2 indicating a fault on any connected units. Terminal CN02 can be used to connect a 7day timer (RBC-EXW21E) or alternatively the RBC-SMTI interface lead can be connected and used as a means of remote switching.

5.3 TCB-PCNT20TLE X&Y Protocol Converter

Description

The device is intended for use on the DI/SDI/SMMS/SHRM ranges of equipment and is designed to convert TCC Link to AI Network protocol. This enables earlier types of control equipment to be interfaced with the current range.

Application The device consists of a PCB and Transformer, which should be installed in or adjacent to the indoor unit. Where indoor units are in “Group Format” it is only necessary to install one device on the lead unit. Typically the protocol converter would be used to integrate new equipment onto an existing AI control system. This may be an RBC-CR1/64-PE Central Controller or a Building Management System of some description.

Diagram

39

Connections Power for the primary side of the Transformer is obtained from the CN309 socket on the indoor PCB. A further connection is then made to the A & B terminals from CN02. Multiple devices would be connected together in a “daisy chain” fashion and each device given a unique address via dipswitches SW01.

Limitations It is recommended that 1.5mm2 2-core screened cable be used on all networks up to a maximum of 500Mtrs.

5.4 TCB-PCNT30TLE TCC Link Network Adaptor

Description

The device is intended for use on all the DI/SDI units other than the KRT High Wall, which is supplied with the adaptor built in. The device is designed to allow Network devices such as Central Controllers and BMS systems to be interfaced.

Application The device consists of a small PCB, which should be installed within the indoor unit and would typically be used where the indoor unit/units will be interfaced with a Central Controller or any other network device, such as a BMS system. One device is required for each indoor unit or group of indoor units. Where indoor units are grouped together they will be assigned with one address on the central device and will consequently all receive the same operational instructions.

Diagram

41

Connections The device connects to the indoor unit PCB via socket CN50 and will provide two terminal network connection designated U3 & U4. Where multiple devices are to be installed it is necessary to set one unit with a 100ohm termination resistance. This would normally be on the device connected to the unit with the lowest network address. The resistance being set by SW01 bit being set to ON. When the device/devices have been installed and a termination resistance applied it is then necessary to apply a unique network and refrigerant line address to each unit.

Addressing Procedure The address setting is carried from a standard RBC-AMT21/31E remote controller. Where units do not have standard remote controllers installed, one should be temporarily attached in order to carry out the configuration process. Accessing the Engineers configuration menu Press Set CL & Check Simultaneously for 4 seconds. Navigate to menu item 12 (refrigerant line address) using the Temperature Set Buttons. Set a unique line address using the Timer Set Buttons and then press SET. Navigate to menu item 03 (network address) using the Temperature Set Buttons. Set a unique network address using the Temperature Set Buttons and then press SET Press the CHECK button to complete the setting process Generally speaking the refrigerant line address would mirror the network address, however this would not be the case with grouped units, which would have the same network address but different line addresses.

Limitations It is recommended that 1.5mm2 2-core screened cable be used on all networks up to a maximum of 500Mtrs in length. The KRT range of units do not require adaptors as they are supplied with U3 & U4 connections and also have a termination resistance facility on the indoor PCB. The termination resistance being set by SW01 bit 1 being set to ON.

6.1 RBC-WP1-PE Windows Control Package

Description The RBC-WP1-PE is a front-end software package that controls all aspects of the air conditioning systems installed on a site. The software is installed on a PC, which then connects to a TCB-IFLN640TLE2 LonWorks gateway for connection to the indoor units. The software allows all of the units operating parameters to be adjusted from the one PC. It allows faults to be reported and re-transmitted via email, fax or text message. The software can be accessed remotely either by telephone or via the Internet. The software can log data and provide graphical representation of data. It has a schedule built-in for time control and it can also be used to reset set points or modes of operation. When the software is installed, it will automatically install the gateways and power meters and it will then generate basic graphics.

Application The software is used when a computer solution is required in order to provide a flexible solution to allow the air conditioning to be fully controlled from one central point. It offers much functionality, which is suited to small and large systems.

Features of the Software Customization

The software being very flexible, it allows for a fully adaptable graphical representation of the building to be included.

Frost Protection The software has the ability to sample the air temperature from an individual or a selection of indoor units. Then, based on this data, operate the air conditioning to give frost and fabric protection to the building

Energy monitoring The energy monitoring software can be included to calculate the running costs of the individual indoor units. This data can then be provided in structured bills for the building tenants. This data is calculated from the demand given from the indoor units and the power consumed by the system. The RBC-EM1-PE power meter is required for this function. This option is covered in a separate data sheet.

43

Control of other devices We have a simple digital Input / Output module that we use to control other plant systems. For example, we could enable boilers or other air-handling units. The module can accept inputs also; examples would be an input from a fire alarm where the air conditioners are shutdown or an input to switch on the air conditioners from an external source. The RBC-DI1 module is required for this function. This option is covered in a separate data sheet.

Diagram

Connection The Windows Package (RBC-WP1-PE) connects to a LonWorks gateway via the AB network. The AB network is connected via a two part screw terminal connector the recommended cable is 2-Core Screened 1.5mm2. The connector is mounted on a full height PCI card that is fitted to the PC Limits The windows package can control up to 1024 indoor units connected through the LonWorks gateways (one gateway required per 64 indoor units).

10.1 Trend Solution (LTX-21)

Description The LTX-21 is a product that has been developed to enable Toshiba air conditioners to directly connect to a Trend BMS system. The LTX-21 connects directly to the Trend outstation supervisor port. The interface is capable of setting all of the operating parameters for each indoor unit. It also provides error codes and the return air temperatures.

Application

The LTX-21 solution is designed to allow connection to a Trend BMS system. It allows a fully functional solution to be achieved. The LTX-21 and associated Toshiba LonWorks gateway are usually mounted in the control panel with the outstation. We have two possible variations, which are outlined below.

LTX-21 and RBC-LG1 Combination

This uses a LTX-21 and an RBC-LG1-PE, which connects to a maximum of sixteen indoor units however; the TCB-PCNT20TLE network adapters are required to convert back to the AI network. This option will be cost effective for single split installations with less than 7 indoor units for all other situations use the solution below.

LTX-21, LTX-VCI and TCB-IFLN640TLE Combination

This solution uses an LTX-VCI and TCB-IFLN640TLE for the control of a maximum of 64 indoor units. The solution uses an LTX-21 for every 16 indoor units as these connect to the Trend outstations. For example, for a total of 64 indoor units you would use four LTX-21’s. In each of the above cases, multiples of the above combinations can be used to accommodate larger systems.

57

11.1 VN Unit Controls Description This section is subdivided into four sections for diferent applications of the VN units. The VN is supplied with a 240V control option as standard this is a starting point but often requires development for specific applications.

Application Option 1

The first option is the simplest form of control it does not allow control with the air conditioner system. The mechanical switch is straightforward to install as it only involves the switching of the relays. If required the fan speed or the damper can be fixed in a particular mode

Option 2

The Second option allows the VN unit to be enabled from an indoor unit this utilizes the RBC-SMFI Fan interface. This link means the unit needs to be operated in conjunction with an associated indoor unit.

Option 3

Option 3 is a low voltage option, which gives a dedicated controller for the VN unit this control option, will allow a Heater to be controlled to protect the fabric of the unit. This option can also be integrated with the indoor units via the RBC-SMFI fan interface.

Option 4

The final option indicates the procedure for connecting and control using interactive intelligence. This allows full control from the PC of the VN unit the units can independently time controlled to only provide ventilation when the building is occupied.

65

Option 1: 3-Gang switch

The simplest form of ventilation heat exchanger unit (VN unit) control is with electro-mechanical switches. These are not supplied by Toshiba but can be obtained from the usual DIY stores. Three switches should be used with one VN unit.

Controls:

ON/OFF (switch 1)

Fan Speed - High/Low (switch 2)

Mode - Bypass/Heat Exchange (Damper on/off) (switch 3) For some of the smaller projects, this may be the most convenient and cost effective solution. Note that this option is only available if there are no Toshiba heaters provided with the heat exchangers.

RBC-SMFI - External Fan Interface (Relay & CN32 Lead)

More than one heat exchanger unit can be connected to the same indoor fan coil unit. In order to do so, the heat exchanger units need to be wired in parallel. However, the current may be too large and an additional higher amperage relay (provided by others) may be required. The RBC-SMFI would then turn the relay ON. Note that this option is only available if there are no Toshiba heaters provided with the heat exchangers.

Option 3: Hard Wired Wall Mounted Controller RBC-VNC1 & RBC-VNP1

The Wall Mounted LCD Heat Exchanger Controller is the RBC-VNC1. The controller MUST be used with the Heat Exchanger PCB (RBC-VNP1) (Incl Pre-Heat, or Re-Heat Control). The PCB is a direct replacement for the original supplied PCB in the heat exchanger unit. Controls:

ON/OFF

Fan Speed - High/Low

Mode - Bypass/Heat Exchange (Damper on/off)

Heater - Adjustable Pre-Heater or Re-Heater activation temperature (if heaters are provided)

In addition to the RBC-VNC1 and RBC-VNP1, a RBC-SMFI can also be connect to the PC board of one indoor unit for ON/OFF option via an indoor fan coil unit.

One RBC-VNC1 and one RBC-VNP1 are required for each heat exchanger unit (even if a heater is not fitted).

Also note that there is a set of contacts on the PCB board (RBC-VNP1), which can be connected back to a BMS system for ON/OFF option only.

Option 4: Interactive Intelligence RBC-VNP1, RBC-DI1-E and RBC-VNT1

Heat Exchanger PCB (Incl Pre-Heat, or Re-Heat Control) Control by Interactive Intelligence can be achieved with the use of DI Modules (RBC-DI1-E). Each of the functions will require one of the eight outputs available from a DI Module: Output 1 - On/Off Output 2 - High/Low Fan Speed Output 3 - Bypass/Heat Exchange (Damper on/off) Output 4 - Heater On/Off (if applicable) The DI module will then be connected to the Windows Package via the AB network. One RBC-VNP1 will be required for every heat exchange ventilation unit (even if a heater is not fitted). An RBC-VNT1 will be required with every heater fitted on this option. This is a manually adjustable thermostat to set the activation temperature
