8 EECTRICA DATA R1, R2, R4, R8, 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. A 230-VAC model 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 resulting from max. 300 ma (irrespective as to whether it is supplied by the controller's internal transformer or by an external source) 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). R3, R5, R6, R7U, 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 "loaded" when besides the inherent load (300 ma) an additional sum load resulting from max. 600 ma is applied to the 24 VAC output terminals. The max. unloaded output voltage at terminals 3 and 4 (24 VAC RSxx) / at terminals 5 and 6 (24 VAC Rxx) is identical with the output voltage of the external supplying transformer. COMMISSIOIG The controller can be used with freely programmable applications or with a configurable application. Freely Programmable Applications All models 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 10 on pg. 14). ibrary Application All models can be used with the library application already included in CPO Studio. The library application has the advantage that it is proven and quickly configured using the wizard available in CPO Studio and then commissioned using the commissioning tool running on an Android Smart device. OTE: Before configuring, if as yet no WA 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 library 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 dxcooling (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. The radiator heating application type uses PID and, optionally, min. temperature limitation. The underfloor heating application type uses PID and, optionally, max. temperature limitation. The intake air / air quality control application type uses PID and, optionally, min. temperature limitation and air quality control. Those inputs/outputs not needed by the configurable application are available for use as free I/Os (like the I/Os of an I/O module) by the plant controller see also CPO- Rxx Room Controller Inst. & Comm. Instr. (E1B- 0591GE51). The use of different application types is limited by the number of I/Os supported by the given model. Supported Actuators The application supports a variety of actuators.

Supported Operating Modes The application supports a variety of different operating modes (e.g., occupied, standby, unoccupied, building pro- E0B-0732GE51 R0717 8

9 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). ighting Application All BOs can be configured for lighting control. When configured for lighting control, binary inputs are automatically assigned for each binary output. Binary outputs are controlled directly by fast logic from the binary inputs without adding any control strategy. Outputs are controlled within 50ms of button press and write to priority table 15. Binary inputs can be configured as pulse O / pulse OFF (two buttons per light output) or toggle (one button per light output). Binary outputs configured for light control can also be written from control strategy at any priority between 8 and 16. The library application provides a single lighting control that includes schedule control integrated with push button control that operates according to a "last wins" mechanism. The available schedule operating modes are 1 = Override OFF 2 = Repeated OFF 3 = OFF 4 = O 5 = Repeated O 6 = Override O OTE: Before using lighting application, consider the relay output types and characteristics in Table 3. 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 which of the controllers located on a given BACnet MS/TP bus are so-called "Masters," and which are so-called "Slaves." The commissioning 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 its Slave. 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. Each Master and each Slave needs to have its own ceiling cold water temperature sensor and its own condensation contact. 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 (OTE: 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.) The Master shares schedule, heat/cool mode, actuator positions, etc. with its Slave(s). OPERATOR ITERFACES EDs The controller features the following EDs: T2 R2 T1 R1! Fig. 9. Controller EDs Table 8. Description of ED behaviors symbol color function, description T2 yellow ot used R2 yellow ot used T1 R1 yellow yellow! yellow green red ED indicating transmission of communication signals via the BACnet MS/TP interface ED indicating reception of communication signals via the BACnet MS/TP interface. Status ED indicating firmware problems, hardware problems, etc. Power ED indicating firmware problems, hardware problems, etc. Watchdog (R7U, only) has locked controller. Watchdog Functionality (R7U, only) The R7U features a watchdog (relay 4) which enhances the system's reliability. The watchdog indicates whether or not the controller's software 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 ED will light up RED, and the status ED will remain OFF (see Table 8). Optionally, the user can connect an alarm (e.g., beeper) to terminals 15 and E0B-0732GE51 R0717

10 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. COMMUICATIO ITERFACES BACnet MS/TP Interface The controller features an RS485 interface (Rx: terminals 62, 63, and 64; RSx: terminals 40, 41, and 42) suitable for BACnet MS/TP communication. The terminal block containing it is black. The cable length affects the baud rate. See Table 9. Table 9. Baud rate vs. max. cable length baud rate max. cable length () 9.6, 19.2, 38.4, 57.6, and 76.8 kbps 1200 m kbps 800 m with an Android Smart device so that the application engineer can commission the controller. OTE: 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 iterature listed in Table 10 on pg. 14. 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. For information on wire gauge, max. permissible cable length, possible shielding and grounding requirements, and the max. number of devices which can be connected to a bus, refer to standard EIA-485.

Current Output of Power Output Terminals of 230 VAC Controllers The 24 VAC power output terminals of the 230 VAC Rxx controllers are terminals 5, 6, 35, 39, 43, and 44 plus pin 4 of the controller's RJ45 interface. Two of these terminals (typically: 5 and 6) will be used to supply the triacs. The 24 VAC power output terminals of the 230 VAC RSxx controllers are terminals 3, 4, 27, and 31 plus pin 4 of the controller's RJ45 interface. Two of these terminals (typically: 3 and 4) will be used to supply the triacs. Regardless of whether the triacs are supplied by that controller's internal transformer or by an external source, the max. permissible combined current output of the aforementioned 24 VAC power output terminals is 300 ma (or 320 ma for max. 2 minutes). Consequently, if only those two 24 VAC power output terminals used to supply the triacs already have the max. permissible combined current output of 300 ma (or 320 ma for max. 2 minutes), then the current output of the remaining 24 VAC power output terminals must, of course, equal zero. Max. Current Output of Power Output Terminals of 24 VAC Controllers The 24 VAC power output terminals of the 24 VAC Rxx controllers are terminals 5, 6, 35, 39, 43, and 44 plus pin 4 of the controller's RJ45 interface. The 24 VAC power output terminals of the 24 VAC RSxx controllers are terminals 3, 4, 22, 23, 24, 25, 27, and 31 plus pin 4 of the controller's RJ45 interface. The max. permissible combined current output of these 24 VAC power output terminals is 300 ma. Relay Outputs CAUTIO 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. OTE: 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 E 45014). Relay Current imitations If the triacs are supplied with current from an external source, then a maximum of two relays may be loaded with a max. of 4 A per relay even if two triacs are each simultaneously loaded with max. 300 ma. If the triacs are supplied with current from an internal source, a maximum of two relays may be loaded as follows: a max. load of 4 A for a relay serving a fan and a max. load of 10 A for a relay serving a reheat even if one triac is simultaneously loaded with 300 ma. Triac Outputs OTE: Recommended fuse (F1): 1.25 A time-lag fuse (IEC). User must consider the correct voltage and max. breaking capacity / interrupting rate (line voltage urgently requires high breaking capacity / interrupting rate). The terminal blocks containing the controller's triac outputs are orange. These triac outputs can be configured 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. OTE: The VC6983 actuator is intended for use at relay outputs, only and must not be used at the controller's triac outputs. Triac Current imitations The max. allowed current with which the ensemble of a controller's triacs may be loaded is dependent upon whether the given model is powered with 24 VAC or with 230 VAC (and, in the case of models powered with 230 VAC, upon whether the outputs are supplied by the controller's internal transformer or by an external current supply). Specifically: In the case of 24 VAC models, the ensemble of a controller's triacs may be loaded with 600 ma. In the case of the 230 VAC models, if the triacs are supplied with 24 VAC current by the controller's internal transformer, the ensemble of a controller's triacs may be loaded with 300 ma (or 320 ma for a max. of 2 minutes); when supplied by an external source, this value is doubled. However, regardless of model and regardless of whether the triacs are supplied internally or externally, a single triac must never be loaded with a current of more than 300 ma (320 ma for max. 2 minutes). evertheless, the ensemble of triacs can be loaded for very short periods of time (on the order of milliseconds) with a current on the order of 2500 ma typically encountered when switching on multiple thermal actuators. 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. 11 E0B-0732GE51 R0717

12 Analog Outputs The terminal blocks containing the controller's analog outputs are green. Analog output types: See Table 5. The analog outputs of the Rxx controllers (large housing) are protected against voltages of max. 29 VAC and 30 VDC (due to, e.g., miswiring). OTE: Connecting 24 VAC to any analog output of the RSxx controllers (small housing) will damage the hardware. Free I/O Option imitations including model-dependent limitations apply. Further limitations are explained below. Free Universal Inputs Max. 5 BACnet Analog Input Objects Under the free I/O option, a maximum of five of the CPO-R controller's unused UIs are available for use as analog inputs by the plant controller. However, they cannot be used for receiving input from I1000TK5000 sensors. Max. 5 BACnet Binary Input Objects Under the free I/O option, a maximum of five of the CPO-R controller's unused UIs are available for use as binary inputs by the plant controller. Max. 2 BACnet Accumulator Objects Under the free I/O option, a maximum of two of the CPO-R controller's unused UIs are available for use as accumulators by the plant controller. These accumulators can have up to 30 Hz (pulse O 16 ms; pulse OFF 16 ms; closed: voltage < 1 V; open: voltage > 5 V). These accumulators can be used, e.g., for energy meters which create pulses when energy is consumed. Free I/O Option Example: In the following example, the customer wants the plant controller to use some of the I/Os of the R2 not used by the application as free I/Os, and therefore hardwires the free inputs/outputs as follows: UI1, 2: used as 0 10V inputs UI3: used as an TC20k temperature input UI4, 5: used as binary inputs UI6: used as a counter AO1: used as an 0 10V output AO2: used as an 0 10V output Triac 1, 2: used as floating actuator outputs Triac 3, 4: used as floating actuator outputs Relay 1, 2, 3, 4: used as binary outputs In the above example, the customer has used the maximum of four analog characteristics. o further analog characteristic can be assigned; e.g. relays 1, 2 could not be used as multistate outputs. TROUBESHOOTIG All units feature a Status ED, Power ED, and Service Button for commissioning and troubleshooting. See also sections "EDs", "Watchdog Functionality (R7U, only)", and "Service Button". Check if the Status ED's behavior is changed if you switch the power OFF/O. Please contact Honeywell if this does not solve the problem. ACCESSORIES Terminal Protection Cover Required for wall mounting. Bulk pack, set of ten covers. For ARGE controllers, order no.: IRM-RC For SMA controllers, order no.: IRM-RSC Free Outputs Max. 4 BACnet Analog Output Objects Under the free I/O option, a maximum of four of the CPO-R controller's unused outputs (analog or binary outputs) may be used with BACnet Analog Output objects by the plant controller. Possible characteristics are as follows: analog output: 0(2)..10 V outputs; floating output: triac or relay outputs; PWM: triac outputs; 1-, 2-, 3-stage output: triac / relay outputs. Max. 4 BACnet Binary Output Objects Under the free I/O option, a maximum of four of the CPO-R controller's unused relays and triacs are available for use as binary outputs by the plant controller. However, they can be used only as O / OFF binary outputs. E0B-0732GE51 R
