Cooling
The menu is only displayed in the Expert level.
Parameters
Setting
Release of cooling mode
Releases the cooling mode for the heating circuit. Additional parameters appear in
menu
Cooling
.
Cooling mode is only possible within the switch times for comfort and normal tem-
perature. Cooling is not possible in the switch times for setback operation
[ch. 6.7.3.6].
Reference line ET min
Minimum external temperature for cooling function.
If the average external temperature exceeds the value set, the operating mode
changes to cooling.
The minimum external temperature is the reference point for
Reference field
flow min
.
Reference line ET max
Maximum external temperature for cooling reference line.
The minimum temperature is the reference point for
Reference field flow
MAX
.
Reference field flow
MIN
Flow setpoint temperature, if the external temperature reaches the
Reference
line ET min
set.
Lower point of cooling reference line.
Reference field flow
MAX
Flow setpoint temperature, if the external temperature reaches the
Reference
line ET max
set.
Upper point of cooling reference line.
Minimum temperature
Minimum flow temperature in heating circuit during active cooling.
Lower limit value for the flow setpoint temperature of the cooling reference line.
Maximum temperature
Maximum flow temperature in heating circuit during active cooling.
Upper limit value for the flow setpoint temperature of the cooling reference line.
Demand increase
The value set is added to the flow setpoint temperature, positive and negative.
The demand increase has the function of a parallel displacement of the cooling ref-
erence line.
