COOLING BASED ON SET TEMPERATURE OR
DEPENDING ON OUTDOOR TEMPERATURE
The cooling can be released based on the outdoor temperature
or in accordance with a fixed temperature (= set temperature).
Cooling based on set temperature
With the “fixed Tp” setting, the supply temperature of the cooling
represents the setpoint temperature set for the mixing circuit 1
(MC 1):
A Temperature
B Time
1 Outdoor temperature
2 fixed Tp ( = set temperature mixing circuit)
Cooling depending on outdoor temperature
With setting “set. AT” set temperatures are ignored. Instead, set
temperatures are automatically calculated based on the outdoor
temperature.
The calculation is based on the value entered in Kelvin under “OT
diff. MC1” but is restricted to a spread of 1 K – 10 K (adjustable in
0.5 steps).
A Temperature
B Time
1 Outdoor temperature
2 Set temperature mixing circiut
3 set. AT (= outdoor temperature difference)
ENABLE ACTIVE COOLING
NOTE
The active cooling function can only be used if the system
is utilised in accordance with the corresponding hydraulic
diagram.
There is otherwise no guarantee that the active cooling
with function properly.
NOTE
For brine/water heat pumps, active cooling is only possible
if the expansion board (extra-cost accessory) is installed.
IMPORTANT
The use of active cooling is generally excluded for brine/
water heat pumps with integrated passive cooling func-
tion.
The active cooling function may only be used if the heating and
heat pump regulators are equipped with software > 3.31.
