Daikin RZP100DVAL [99/255] Suction pipe superheat protection control only in heating operation

Daikin FHYP35BV1 [99/255] Suction pipe superheat protection control only in heating operation
Function Details SiE25-110
90 Function and Operation
4.2.18 Suction Pipe Superheat Protection Control (Only in heating
operation)
In heating operation, controls compressor operating frequency to prevent oil from remaining in
the outdoor unit heat exchanger by the continuous operation of compressor at high superheated
degree of the suction pipe.
4.2.19 Inverter current protection control
Restricts compressor operation frequency to prevent compressor from tripping due to inverter
overcurrent.
Drooping current
4.2.20 Control by inverter fin temperature
Restricts compressor operation upper limit frequency to prevent compressor from tripping due
to inverter fin temperature.
