Min. supply temperature
Options:
0...3...100 °C
The supply setpoint temperature output by the module is limited using this parameter. This is a
safety function that ensures a supply setpoint temperature too low for the cooling system is not
output under any circumstances. For example, the supply setpoint temperature for cooling ceiling
can be limited to minimum 14 °C.
