The defrost ends when the NTC combined defrost probe 1 or 2 increases over dF11 (circuit1) or dF13
(circuit2).
37.6 MANUAL DEFROST
The manual defrost key function is enabled if the unit is on with at least one compressor running.
The defrost start temperature/pressure of the controlled probe must be lower than dF02 setpoint value while
if the combined defrost is active the detected temperature must be lower than dF10 or dF12.
At this point by pushing
key in the “Defrost status of the circuit” visualization, the defrost starts.
ATTENTION:
the manual defrost is not related to the dF09 /dF06 delay times, therefore the forced defrost
cycle, if condition are OK, is immediately executed for both circuits.
37.7 DEFROST IN UNIT WITH TWO CIRCUITS
Start defrost in unit with common condenser
37.7.1
Parameter involved: dF22
0= Independent
1= Only if both circuit conditions are satisfied
2= At least one circuit condition is satisfied
End defrost in unit with two condenser
37.7.2
Parameter involved: dF23
0= Independent
1= Both circuits have reached the conditions to stop the defrost
2= At least one circuit has reached the end defrost condition

ATTENTION:
The configuration error ACF1 is displayed if the parameter value of dF22 and dF23 is not permitted.
For only one condensing unit the dF22 and dF23 values must be not equal to 0.
37.8 DEFROST WITH CONDENSER FAN PROCEDURE
DEFROST WITH CONDENSER FANS
If dF01 = 4 defrost is activated only through the condenser fans.
If the temperature detected by the probe configured as external air temperature > dF26, instead of reverse
the cycle, the compressor is stopped and is activated the condenser fan.
The defrost ends:
If the combined defrost is ON, for temperature or max time
If only NTC probes are configured, for temperature or max time
If only pressure probes are configured, for max time
