Short description
Control of the device series P-22RT..-1U00..-2 from Belimo Typical application: room control unit in a zone\
Guidelines - Software creation
Supported Modbus - Function Codes: 2, 3, 4, 6 and 16. For addressing use the address numbers, not the register addresses. Registers from 111 are persistent in the device and must not be written cyclically. Unused registers contain the value 65535 (unsigned) (FFFF - hex) or -1 (signed). Unused registers within the defined ranges may be read/written. In the constellation ‘eEcoBoostOnOffIconMode = BELIMO_P_22RTX_1U00X_2_FULL_ICON_MODE.OPERATION_MODE’, in ECO mode the first rising edge on the input ‘xBoostIcon’ switches to On/Comfort mode. On the second rising edge the BOOST mode is then activated. When operated at the room control unit the switch from ECO to BOOST happens immediately. Remedy: Write address 30 with FC06 !!! with the desired value, do not write address 22 at the same time. Measured values - calibration: Class 4\

Function description
General
This function block controls room control units of the device series P-22RT..-1U00..-2 from Belimo via Modbus communication. The configuration (addresses 110 - 149) is done internally in the function block with the index ‘_FULL’, externally in the function block with the index ‘_EASY’.\
Operating modes - room control unit (address 30) — outputs ‘eOperationMode’ and ‘xModeDev’
Four operating modes are distinguished: 0: Off/Protection (‘xModeDev’ = FALSE) 1: On/Comfort (‘xModeDev’ = TRUE) 2: Eco Mode (‘xModeDev’ = TRUE) 3: Boost Mode (‘xModeDev’ = TRUE) Operating modes 2 and 3 can only be selected in addition to operating mode 1. Operating mode 3 is active for a limited time and requires the enabling of the highest fan stage for correct function. The operating modes are set automatically depending on the operating method (see below). \
Central definition of the functions of the icons / controls 'OnOff', 'Eco' and 'Boost' (operating methods)
A total of four operating modes are distinguished, which are defined via addresses 139 - 141: (FULL: parameter ‘eEcoBoostOnOffIconMode’, EASY: contents of addresses 139 - 141 to be set externally according to the following listing.) \

In DISPLAY mode the operating modes Eco Mode and On/Comfort are determined by the inputs ‘xEcoIcon’ and ‘xMode’ (TRUE = on). If none of the inputs is active, the Off/Protection operating mode is automatically selected. In OPERATION mode the operating modes ECO, Boost and OnOff are determined by the associated inputs (rising edges) and by the operation at the room control unit. In PRESENCE-BUTTON mode the operating modes Off/Protection and On/Comfort are determined by the input ‘xMode’ (rising edges: On/Comfort, falling edge: Off/Protection) and in parallel by the operation at the room control unit. On every change from night to day operation and vice versa, triggered by the room control unit, a pulse with the duration ‘tTimeButtonPulse’ is generated at the output ‘xButtonPresence’. \
Day mode / Night mode (output ‘xModeDev’)
The output ‘xModeDev’ shows the current state of day mode at the room control unit (TRUE = day mode).\
Room setpoint temperatures
The room setpoint temperatures are defined in different ways depending on the parameter ‘eSetpTempMode’ (address 145): \
Absolute setpoint (e.g. +23.5 degrees Celsius) (index ‘Abs’) (inputs ‘rSetpTempAbsNight’, ‘rSetpTempAbsBaseDay’) (output ‘rSetpTempAbs’)\
Relative setpoint (e.g. +1.0 Kelvin) (index ‘Rel’) (inputs ‘rSetpTempRelNight’, ‘rSetpTempRelBaseDay’) (output ‘rSetpTempRel’)\
Changes to the assigned inputs are transferred immediately in the corresponding state, otherwise on the next transition to that state. Example: A change at the input ‘rSetpTempAbsNight’ is transferred and becomes effective immediately in night operation. Example: A change at the input ‘rSetpTempBaseDay’ is not effective immediately in night operation, but only on the next transition to day operation. Changes to the parameters ‘rAdjCenterSetpTempAbs’ (address 146) or ‘rAdjOffsetSetpTempAbs’ (address 147) are transferred immediately in the appropriate mState, otherwise delayed. (FULL). Changes to addresses 146 or 147 are captured after re-reading the configuration and transferred accordingly (EASY). Changes to the content of address 146 affect only the absolute setpoint temperature; changes to the content of address 147 affect the absolute and relative setpoint temperature. The current values at the inputs ‘rSetpTempAbsNight’ and ‘rSetpTempAbsBaseDay’ must be specified depending on the parameter ‘eTemperatureUnit’ (address 120). The current setpoint is then available at the output ‘rSetpTempAbs’ in the chosen unit. The current values at the inputs ‘rSetpTempRelNight’ and ‘rSetpTempRelBaseDay’ must be specified depending on the parameter ‘eOffsetUnit’ (address 122). The current setpoint is then available at the output ‘rSetpTempRel’ in the chosen unit. Night operation - room setpoint temperature When switching from day operation to night operation the state at the input ‘rSetpTempAbsNight’ is transferred to the room control unit and displayed there (‘eSetpTempMode’ = absolute setpoint temperature). When switching from day operation to night operation the state at the input ‘rSetpTempRelNight’ is transferred to the room control unit and displayed there (‘eSetpTempMode’ = relative setpoint temperature). Any change of the state at the input ‘rSetpTempXXXNight’ is transferred to the room control unit during night operation. Day operation - room setpoint temperature Case 1 - No valid room setpoint temperature for day operation exists yet When switching from night operation to day operation the state at the input ‘rSetpTempAbsBaseDay’ is transferred to the room control unit and displayed there. At the room control unit an adjustment within the symmetric range defined by address 147 is possible. The step size is 0.5K. Case 2 - A valid room setpoint temperature for day operation already exists When switching from night operation to day operation the previous valid room setpoint temperature is transferred to the room control unit and displayed there. At the room control unit an adjustment within the symmetric range defined by address 147 is possible. The step size is 0.5K.\
Output ‘xDI1’
At output ‘xDI1’ the state at input DI1 of the room control unit is available in different ways (parameter ‘xDI1OutpMode’). Operating modes RAW The output immediately adopts the state at input DI1 (FALSE: contact open, TRUE: contact closed with +24VDC) PULSE Each rising edge at input DI1 triggers a pulse of duration ‘tTimeDIPulse’ (default: 1s) at the corresponding output xDI1. \
Specification / display of the fan stage
The preselection of the number of fan stages is made via the parameter ‘eFanLevelConfig’ (address 148). In Boost Mode the maximum fan stage (independent of the input ‘eSetpFanLevel’) is forced. The fan stage is selected and transmitted via the input ‘eSetpFanLevel’ within the permissible limits. The current fan stage is output via the output ‘eFanLevel’ within the permissible limits. The display of the current fan stage and the adjustment options are additionally determined by the parameters ‘eFanStagesControlMode’ (address 31) ‘eFanControlMode’ (address 149), ‘eFanLevelConfig’ (address 148) and ‘xDsplFanStages’ (address 138).\
Evaluation of the current CO2 level using a multicolored LED
The evaluation of the current CO2 level is done by a multicolored LED (off / green / yellow / red) and the output ‘eCO2Status’. The threshold for the LED color transition from green to yellow is defined by the parameter ‘rCO2_LED_ThresholdwGreenYellow’ (address 115). The threshold for the LED color transition from yellow to red is defined by the parameter ‘rCO2_LED_ThresholdYellowRed’ (address 116). The evaluation and LED display can be defined by the parameter ‘xCO2_LED_Enable’ (address 117) (TRUE = display).\
Display of symbols / actual values
The display of the desired symbols on the room control unit's display is triggered by the TRUE state of the associated inputs. These inputs are identified with the index ‘Dspl’. Example: xDsplTemp = TRUE causes the current room temperature to be displayed.\
Display of faults
Faults are indicated at the collective output ‘xAlarm’ (= TRUE). It includes communication faults (time delay: gc_Parameters.gc_tOnDelayxAlarmCom, default = 60s) and device faults (direct). Here the collective error message, the collective warning message and excessively high CO2 level (LED = red) are output as device faults. At the output ‘eErrorCodeCom’ an explanatory text for the cause is provided in case of a communication error. It always shows the cause of the last communication error.
