Heat pump is always released
The heat pump is released when the composite outside temperature lies above the
adjusted value. The heat pump is locked when the outside temperature lies below the
adjusted value.
The switching points for release and locking are separated by a switching differential to
absorb small outside temperature variations.
Refer to “Release of outside temperature” (above operating line 630).
