Use This function is used to specify the same room temperature in all controllers in the same room. It is used when a room point @TCR incorporates more
than one controller, i.e. @TCR.TEC(m) > 0 for m = 1, 2, … The averaging function is a feature of the BPS TEC master.
It is only enabled if parameter is set to @TCR.ROOMC = 1.
ARTP selector logic The CFE software uses the following selector logic for the value of ARTP:
@TCR.ARTP(x) = nvoTempSensor (controller output), if nviSpaceTemp (controller input) is integrated
@TCR.ARTP(x) = nvoSpaceTemp (controller output), if nviSpaceTemp (controller input) is not integrated.
Bindings required In accordance with the selector logic, the following bindings are required:
For each controller with
a local temperature sensor, bind NVs nvoTempSensor and nviSpaceTemp to the NIDES.RX
Sensor on room unit A distinction is made in Application Library V2 between a local room sensor on the controller (nvoTempSensor) and a room sensor on the operator unit
(nvoTempSensorPPS). For integration into VISONIK, in the second case, a binding is required between the controller output nvo TempSensorPPS and
the NIDES.RX input nviTempSensor.
Example The following diagram shows the bindings required for two controllers with and one controller without a local room sensor.
