Enabling and blocking active cooling mode
The cooling function must be set by your
heating contractor.
If the cooling capacity with the natural
cooling function (for an explanation see
page 63) is inadequate, the heat pump
control unit can start the active cooling
function.
Constant operation of active cooling
mode results in high electricity consump-
tion. You can enable and block the active
cooling mode individually.
