Heating
High outdoor ambient (overload conditions):
In heating overload conditions, the outdoor fan speed will be adapted to secure the differential
pressure between high and low pressure.
Only the fan speed will be adapted in heating overload conditions.
No adjustments to the compressor frequency will be made.
