7.3.4.7 Heating circuit room frost protection limit
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.
7.3.4.8 Mixed heating circuits cooling switch-over
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
