12.1.18 RTC — Status control value of additional cooling stage
Name
RTC: Status control value of additional
cooling stage
–
The 1-bit communication object is used to operate a switching actuating drive, e.g. a cooling
ceiling, that is controlled by a switching/heating actuator.
–
The 1-byte communication object is used to control an actuating drive with a continuous
input value (0%..100%), e.g. an electromotive actuating drive.
Notice
The additional stage can also be used as a parallel second cooling stage. To do
this, the parameter for the temperature difference to the basic stage must be set
on 0°C.
12.1.19 RTC - Control On/Off
Name
RTC: Control On/Off
RTC: Control On/Off (master)
RTC: Control On/Off (slave)
If a telegram with value "0" is received, the controller switches to Off mode and regulates the
temperature to the setpoint value for frost/heat protection. When the controller is switched on
again, the remaining operating mode communication objects are queried in order to determine
the new operating mode. If the control of the temperature is switched on or off, the new status is
signalled to the bus via this object.
Notice
When the master/slave operation is activated, the object "RTC: Control On/Off
(master)" of the master device must be connected with object "RTC: Control
On/Off (slave)" of the slave device.
12.1.20 RTC - Actual temperature
Name
RTC: Actual temperature
RTC: Actual temperature
weighted
RTC: Actual temperature
■
–
The communication object outputs the measured (room) temperature, adjusted by the
calibration value.
RTC: Actual temperature weighted
■
–
The communication object outputs the temperature value which is calculated from the
recording and weighting of the internal temperature with up to two external
temperatures.
