the control panel on the indoor unit and the operation is as the following.
CS-C45FFH / CU-C45FFH
Time Delay Safety Control
3 min.----If the compressor stops, it will not restart within 3 minutes.(Protection of compressor).

Anti-Freezing Control
If temperature of evaporator is lower than 2
continuously
for 4 minutes, the compressor will cease to prevent the
evaporator from freezing. Fan speed setting will not be
changed.
When temperature of evaporator reaches 10 ,compressor
will restart in 3 minutes.
During Cooling Mode Operation, the Time Delay Safety
Control is available.

If th e temperature of outdoor heat exchanger is belo w 12 , a ten-minutes timer will sta rt timing . When the
situation persists for 10 minutes, the compressor will stop and time delay safety control is ava ilable. When
the temperature of outdoor heat exchanger rises to 13 .5
or a bove, the timer can be reset.

When the compressor is started, within 30 seconds ,
the outdoor fan speed is controlled by the temperature
of outdoor heat exchanger. (Refer to Outdoor Fan Motor
Control)
The fan speed changes every two minutes and it is determined
by the tem perature of 1
