The controller determines the required flow temperature at a specific composite outside
temperature. The cooling curve is determined by defining two fixed points (the flow
temperature setpoint at 25°C and 35°C).
The programmed cooling curve is based on a room setpoint of 25°C. If the room
setpoint is adjusted, the cooling curve automatically adapts to the new value.

913 Locking period at end of heating
If the composite outside temperature rises above the cooling limit temperature, cooling
is released; cooling is disabled when the outside temperature drops to at least 0.5°C
below the cooling limit temperature.
To avoid too rapid a change to cooling at the end of the heating phase, the cooling
function is disabled for the period which can be set here. This "locking period" begins
when there is no heating demand from heating circuit 1.
The locking period is ignored if the cooling function is enabled via the operating mode
button.

920 Summer compensation setpoint increase
In summer, the cooling comfort setpoint (902) is shifted upwards as the outside
temperature increases. This saves cooling energy, and prevents too great a differential
between the room and outside air temperature.
Summer compensation starts to take effect at the outside temperature set here. If the
outside temperature continues to rise, the comfort setpoint is raised in parallel.
