Fig. 1. CPO-Rxx (without optional covers)

GENERAL The CPO-Rxx family of room controllers provide flexible, con-figurable, demand-led control that delivers tangible benefits to reduce energy spends and drives new levels of functionality and efficiency in today’s buildings. With scalable and freely programmable BACnet MS/TP-based room controllers, smart engineering & commissioning tools, and SYLK technology, multiple and flexible configurations can be achieved to address specific applications.

FEATURES • Designed to control terminal units such as 2- and 4-pipe

fan coil units, chilled ceilings, hydronic, air quality control, and a mix of these applications.

• For complex applications requiring high I/O count. • Both configurable and freely programmable, covering

enhanced applications. • Support for 1-3 stage fans, variable fan speed drives

(VSDs), thermal, floating, and proportional actuators. • Dual-loop support allows for 2-room application. • Auto Mac-addressing. • Fast commissioning using plug-and-play solutions, pre-

defined applications and state-of-the-art commissioning via the RoomUp mobile application – eliminating the need for two people when commissioning.

• Reduced number of sensors because sensors are shared across different applications.

• BACnet BTL®-Listed as Advanced Application Controllers (B-AAC) rev 1.12.

• Two housing dimensions and several different I/O versions to match your individual needs.

• 24 VAC and 230 VAC versions. • Universal mounting options, including terminal covers and

color-coded terminals. • The 230 VAC models feature 24 VAC aux. output voltage,

allowing direct connection and powering of field devices. • Two-wire polarity-insensitive bus interface to connect to

Honeywell Sylk wall modules. • All models with real-time clock. RL4, RL5, RL6, and RL7U

with super capacitor for 72-hr data retention.

EN0B-0732GE51 R0616 8

ELECTRICAL DATA RL1, RL2, RL4, RL8, RS1, RS2, RS3, RS4 (230 VAC) Power via terminals 1 + 2: 230 VAC +10% / -15%, 50/60 Hz.

Max. power consumption (when unloaded): 8 W. Max. power consumption (when loaded): 18 W.

The controller is "unloaded" when it has no external load. Thus, the only load on the controller is the inherent load (8 W) of the electronics, themselves. The heat dissipation then amounts to 8 W. The controller is "loaded" when – besides the inherent load – an additional sum load of max. 300 mA is applied to the 24 VAC output terminals. The max. unloaded output voltage at terminals 3 and 4 is 33 VAC (typically: 29.5 VAC).

RL3, RL5, RL6, RL7U, RS5, RS6 (24 VAC) Power via terminals 3+4: 24 VAC 20%, 50/60 Hz.

Max. current consumption (when unloaded): 300 mA. Max. current consumption (when loaded): 900 mA.

The controller is "unloaded" when it has no external load. The heat dissipation then amounts to 7 W. The controller is "loaded" when – besides the inherent load (300 mA) – an additional sum load of max. 600 mA is applied to the 24 VAC output terminals.

COMMISSIONING The controller can be used with freely programmable applications or with a configurable application.

Freely Programmable Applications Of the 14 models of the controller, eleven (see Table 1) can be used with applications which the application engineer can freely program for each controller. This process is performed on a PC on which the CPO Studio software program has been installed (see also Table 9 on pg. 12).

Configurable Application All 14 models can be used with the configurable application already included in the controller. Three models (RS2, RS3, and RS6) can be used only with the configurable application (i.e., they are not freely programmable).

The configurable application has the advantage that it is proven and quickly commissioned using the RoomUp commissioning tool running on an Android Smart device.

Configuration and commissioning can be performed using the RoomUp commissioning tool available in the Google Playstore (URL: https://play.google.com/store ).

NOTE: Before configuring, if as yet no WLAN is present, the commissioning engineer will require a BACnet WiFi Adapter (order no.: BACA-A) to establish wireless communication between his Android Smart device and the controller.

Example Application Types The configurable application supports the following application types:

▪ The FCU application type supports 1-, 2-, and 3-stage or variable-speed fan. It also supports water cooling, water heating (2-pipe or 4-pipe), electric re-heating, and dx-cooling (incl. fan interlock). It supports PID and, optionally, cascade control as well as min. temperature limitation. This application type may be used in combination with other types (see following).

▪ The chilled/heated ceiling application type uses PID with dewpoint protection (2-pipe or 4-pipe). It also supports 6-way valve on AO. It may be used in com-bination with other applications (e.g., min. temperature).

▪ The radiator heating application type.

▪ The underfloor heating application type uses PID and, optionally, max. temperature limitation. It may be used in combination with other applications.

▪ The intake air / air quality control application type for cooling and air quality control uses PID and, optionally, min. temperature limitation. It may be used in combination with other applications.

The use of different application types is limited by the number of I/Os supported by the given model.

Supported Actuators The application supports open/close, PWM (thermal), floating, and proportional (0[2]…10 V) actuators. Proportional actuators may be used with 6-way valves for heating and cooling, in chilled/heated ceilings.

Supported Sensors A variety of sensors (e.g., room temperature sensors, supply temperature sensors, condensation switch, window sensors, occupancy sensors, and card readers) may be used to optimize control quality.

Supported Operating Modes The application supports a variety of different operating modes (e.g., occupied, standby, unoccupied, building pro-tection, fan automatic/manual/fan, only [FCU application type, only], night purge [intake air application type, only]).

I/Os not used by the configurable application may be used by a plant controller for monitoring or to switch an actuator (e.g., window actuator).

Automatic MAC Addressing In contrast to many other MS/TP controllers, the CPO-R Controller features automatic MAC addressing. There is thus no need to manually set the MAC address.

BACnet MS/TP Master/Slave Functionality During configuration, the commissioning engineer can identify (e.g., using the RoomUp configuration tool) which of the controllers located on a given BACnet MS/TP bus are so-called "Masters," and which are so-called "Slaves." The com-missioning engineer is not allowed to assign more than a single Master to each Slave; this is the only action which the commissioning engineer is required to perform. The Slave controller will inform its Master that it has been assigned to be


EN0B-0732GE51 R0616 9

its Slave. Once this is done, Master/Slave communication is as shown in Fig. 9.

Fig. 9. Master/Slave communication

The given application in the Master controller defines how this group (consisting of the Master controller and its Slave controllers) reacts to sensor inputs.

Examples:

▪ Activation of a window contact (indicating an opened window) will cause the application to stop heating/cooling.

▪ Receipt of a condensation signal will stop cooling. ▪ Occupancy will be detected if one of the occupancy

sensors detects occupancy. ▪ A key card will be detected if one of the key card sensors

detects a key card. ▪ Occupancy override from one of the connected wall

modules will trigger an occupancy override. ▪ The last setpoint change (temperature setpoint or fan

speed setpoint) on one of the wall modules (T7460x or TR40x/TR42x) will define the setpoint (NOTE: All TR42x wall modules will show the actual settings used by the controllers. The T7460x and TR40x do not feature a display and are thus unable to provide the actual setting, nor does their setpoint wheel reflect setpoint changes enacted using another wall module in the same group).

▪ For such sensor values as temperature, CO2, and humidity, the commissioning engineer can configure the use of the average, min., or max. value (thus improving system robustness against failures of a single sensor.)

▪ A changeover signal from one of the controllers will set the group to the corresponding mode.

▪ The Master shares schedule, heat/cool mode, night purge, emergency, and actuator positions with its Slave(s).

OPERATOR INTERFACES LEDs The controller features the following LEDs:

red Watchdog (RL7U, only) has locked controller.

Watchdog Functionality (RL7U, only) The RL7U features a watchdog (relay 4) which enhances the system's reliability.

The watchdog indicates whether or not the controller's soft-ware and processor are functioning properly. In the event that either the software or the processor is not functioning properly, the watchdog will reboot the controller.

If, after this reboot, the watchdog again detects a problem, the watchdog will then lock the controller (i.e., permanent reset). The following will then occur: The watchdog will operate (i.e., terminal 15 will be connected with terminal 17), the power LED will light up RED, and the status LED will remain OFF (see Table 7).

Optionally, the user can connect an alarm (e.g., beeper) to terminals 15 and 17.

The watchdog relay is not available for use by the application.

See also Table 3 for technical details on the watchdog relay.

Service Button The controller's Service Button is used to trigger dedicated events.

Fig. 11. RJ45 interface and BACnet WiFi Adapter

CAUTION It is permitted to connect only the BACnet WiFi Adapter to this RJ45 connector. Do not connect IP!

A BACnet WiFi Adapter can be connected to the controller's RJ45 connector in order to establish wireless communication with an Android Smart device so that the application engineer can configure the controller (using the RoomUp configuration tool).

NOTE: When the BACnet WiFi Adapter is connected to the controller's RJ45 connection, it is powered by the controller. It is then prohibited to simultaneously power the BACnet WiFi Adapter via a wall adapter. When, on the other hand, the BACnet WiFi Adapter is instead connected to the controller's BACnet MS/TP interface, it is prohibited to simultaneously use an RJ45 plug; instead, the BACnet WiFi Adapter must then be powered by a wall adapter (standard 5-V USB wall adapter with micro USB connector).

See also corresponding Technical Literature listed in Table 9 on pg. 12.

Wall Modules The T7460x and TR40x/TR42x Wall Modules can be used in conjunction with the controller to perform room temperature sensing, setpoint adjustment, fan speed manual override, and occupancy override.


EN0B-0732GE51 R0616 11

I/O TERMINALS Relay Outputs

CAUTION Mixing of different voltages (e.g., 24 V and 230 V) within the relay block is not allowed.

The terminal blocks containing the controller's relay outputs are orange. Relay output types: See Table 3.

NOTE: If inductive components are to be connected to the relays and if these relays switch more often than once every two minutes, these components must be prevented from causing harmful interference to radio or television reception (conformance with EN 45014).

Triac Outputs The terminal blocks containing the controller's triac outputs are orange.

These triac outputs can be configured (using, e.g., the RoomUp configuration tool) for a variety of different functions, e.g., for connection to either a floating drive or to a thermal actuator. Once the triac outputs have been configured, the corresponding devices can then be connected to them directly.

NOTE: The VC6983 actuator is intended for use at relay outputs, only and must not be used at the controller's triac outputs.

Triac Current Limitations In the case of the 230-VAC versions of the controller, when the triacs are to be supplied with 24-VAC power from the con-troller's internal transformer, then the following applies:

▪ 300 mA max., i.e., a max. of one thermal actuator for heating and one thermal actuator for cooling can be operated (provided that heating and cooling are not operated at the same time).

CAUTION The max. permissible power output of all 24 VAC terminals combined is 300 mA! If the triacs, alone, are loaded with 300 mA, then it is not permitted to connect a load at any other 24 VAC output terminal.

In all other cases, when the triacs are to be supplied with power (24 VAC or 230 VAC) from an external source, then the following applies:

▪ 700 mA (peak) and 600 mA (max.), i.e., two to three thermal actuators can be operated in parallel (depending upon the current consumption of the given actuator).

Universal Inputs The terminal blocks containing the controller's universal outputs are blue. Universal input types: See Table 4.

The universal inputs are protected against voltages of max. 29 VAC and 30 VDC (due to, e.g., miswiring).

Bias Resistors Each universal input is equipped with one bias resistor.

Analog Outputs The terminal blocks containing the controller's analog outputs are green. Analog output types: See Table 5.

The analog outputs of the RLxx controllers (large housing) are protected against voltages of max. 29 VAC and 30 VDC (due to, e.g., miswiring).

NOTE: Connecting 24 VAC to any analog output of the RSxx controllers (small housing) will damage the hardware.
