This function determines the room temperature of the 
corresponding heating circuit during switch-off mode with frost 
protection active 

•  during holiday mode 

•  in automatic mode between the heating cycles with active 

ECO function (see parameter 1 - Reduced mode). 

•  in constant reduced mode with active ECO function (see 

parameter 1 - Reduced mode) 
 

In conjunction with a wall device, the heating circuit is adjusted to 
the frost protection room temperature. 
Without a wall device, the set value serves as a specification for 
the lowered room temperature and is adjusted to it. 

 

With continuous frost protection mode and sensitive objects in the 
house like antiques, plants, etc. the set value is to be adjusted 
accordingly. 

 

If the cooling function was activated at a variable output 
("Hydraulics" menu, parameters 6 and 7, setting 25), the 
additional parameters appear in the "System Parameters" menu, 
parameter 25 and in the "Mixed Heating Circuit 1"/"Mixed Heating 
Circuit 2", parameter 28. 

The cooling function must also be activated via parameter 28 
"heating circuit cooling setpoint temperature" in the "Mixed 
Heating Circuit 1"/"Mixed Heating Circuit 2" menu for each 
heating circuit. 

The cooling function for the corresponding heating circuit is 
active; if a setpoint temperature was configured (<> OFF), the 
cooling function is active for the corresponding heating circuit. 

The output for the cooling function works without pump forced 
operation. 

 

If a wall device is connected to a heating circuit, all factors that 
influence a room remain ignored during active cooling (correction
