Daikin RZQS100B7V3B [95/344] Inverter cooling fin temperature control
Frequency Regulating Functions SiBE27-702
82 Functional Description
4.10 Inverter Cooling Fin Temperature Control
Outline This control will restrict the compressor upper limit frequency in order to protect the electronic
components in the switch box from overheating (L4-error activation).
By lowering the compressor frequency, the current drawn by the compressor will be reduced
and as a result the temperature inside the switch box will drop.
