Additional cooling stage
Number
4
Description:
1. This object is used to operate a switching actuating drive, e.g. a thermoelectric positioner,
that is controlled by a switching/heating actuator.
2. This object is used to control an actuating drive with a continuous input value (0%..100%),
e.g. an electromotive actuating drive.
Note
The additional stage can also be used as a parallel second cooling stage. To do
this, set the parameter for the temperature difference to the basic stage to 0°C.

11.5.5
Control On/Off
Number
5
If a 0 telegram 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 objects are queried in order to determine the new operating mode.
Note
About item 2:
During active ON/OFF controller function in master/slave mode the ON/OFF
(master) control object is to be linked with this object.
About item 3:
During active ON/OFF controller function in master/slave mode the ON/OFF (slave) control
object is to be linked with this object.

11.5.6
Actual temperature
Number
6
1. The object outputs the measured (room) temperature, adjusted by the calibration value.
2. The object outputs the temperature value which is calculated from the recording and
weighting of internal and up to two external temperatures.
Note
An external temperature measurement for room control may be practical for larger
rooms and/or floor heating.
