Heating control value
Number
Name
Object function
Data type
1
Heating control value (control
value heating/cooling)
Output
1. Switching
2. Percent (0 to
100%)
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.

Object function
Data type
2
Additional heating stage
(additional heating/cooling stage)
Output
1. Switching
2. Percent (0 to
100%)
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 heating stage. To do
this, set the parameter for the temperature difference to the basic stage to 0°C.
