SiBE28-804
Frequency Regulating Functions
Functional Description
77
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.
RZQ100~140C7, RZQS125·140C7V1B
RZQ71C7, RZQ71·100C7V1B
Only the fan speed will be adapted in heating overload conditions.
No adjustments to the compressor frequency will be made.
4.12 Oil Recovery Operation
Outline
When the compressor operates for a certain period of time at low frequency, the oil level in the
compressor may become low due to incomplete oil return.To prevent damage to the
compressor and in worst case avoid compressor lock, an oil recovery operation will be
conducted.
Details
During the oil recovery operation, the operation frequency of the compressor will be increased
for a time period of 5 minutes.Oil recovery operation is only executed in cooling mode.In heating
mode, oil return to the compressor is guaranteed by the defrost operation.
