Low temperature protection
If the temperature detected by probe selected with FS62 parameter is lower than FS63 set point, the free
cooling is disabled.
The free cooling will be enabled when temperature detected by probe selected with FS62 parameter is
higher than FS63 + FS64.
44.1 FAN SPEED CONTROL IF COMPRESSORS AND FREE COOLING ARE USED
FOR COOLING (CF97=3)
When the free cooling is not active the condenser fan speed is managed like standard regulation.
If free cooling is active:
outside temperature > FS43 + FS44: condenser fan speed is forced at maximum speed
outside temperature < FS43: when outside temperature decreases below FS43 temperature, after
FS45 minutes the condenser fan speed is managed as standard regulation
45. RECOVERY FUNCTION
The recovery function is Enabled if:
1 Par.
