7.3.4.7Heating circuit room frost protection limit

Function

•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.

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

7.3.4.8Mixed heating circuits cooling switch-over

Function 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.

Wall device functionality limitation:

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