At the end of the dF09 time count the device sees the temperature of the circuit n° 3 combined defrost NTC
probe. If the temperature is below the dF12 set, the defrost procedure is performed otherwise it continues to
function in heating mode. As soon as the temperature drops below the set, it performs defrost.
dF13 Start temperature set of circuit n° 4 defrost cycle.
Allows to set a temperature set below which the defrost cycle takes place.
At the end of the dF09 time count the device sees the temperature of the circuit n° 4 combined defrost NTC
probe. If the temperature is below the dF13 set, the defrost procedure is performed otherwise it continues to

dF14 End temperature set of circuit N° 1 defrost cycle
Allows to set a temperature set above which the defrost cycle ends.
the defrost cycle ends when the temperature detected by the combined defrost NTC probe reaches the set
dF15 End temperature set of circuit n° 2 defrost cycle
Allows to set a temperature set above which the defrost cycle ends.
the defrost cycle ends when the temperature detected by the combined defrost NTC probe reaches the set
dF16 End temperature set of circuit n° 3 defrost cycle
Allows to set a temperature set above which the defrost cycle ends.
the defrost cycle ends when the temperature detected by the combined defrost NTC probe reaches the set
dF17 End temperature set of circuit n° 4 defrost cycle
Allows to set a temperature set above which the defrost cycle ends.
the defrost cycle ends when the temperature detected by the combined defrost NTC probe reaches the set
dF20 forcing off all resources available in ON in circuit n° 1
0= disabled
1= enabled
dF19 forcing off all resources available in ON in circuit n° 2
0= disabled
1= enabled
dF20 forcing off all resources available in ON in circuit n° 3
0= disabled
1= enabled
dF21 forcing off all resources available in ON in circuit n° 4
0= disabled
1= enabled
dF22 switch-on delay time between defrost steps
dF23 Enabling of the condensation ventilation in ON during defrost/dripping
0 = Disabled
1 = Enabled only in defrost mode
2= enabled in defrost and in dripping
The condensation ventilation is blocked during defrost.
If dF23 = 1 and the condensation pressure/temperature rises above the dF24 set, fan switch/on is forced.
The fans are regulated in the same ways as in cooling mode.
If dF23 = 2 during dripping time (dF08 if set different to 0) ventilation is forced to maximum for the time set in
dF08.
If dF23 = 2 and the external air probe has been configured during the dripping time (dF08 if set different to 0)
if the temperature > than dF25 ventilation is forced to maximum for the time set in dF08.
dF24 Forcing pressure/temperature in ON of the fans during defrost
Allows to set a temperature/pressure set above which the fans switch-on.
dF25 Fans temperature set enabling in ON with defrost with condensation fans
Allows to set a temperature set above which the fans switch-on.
dF26 determines the start of the defrost cycle in units with two circuits
defrost mode
0= independent
1= if both have reached the defrost start request
2= if at least one has reached the defrost start request
dF27 determines the end of the defrost cycle in unit with two circuits and unique condensation ventilation
defrost mode
0= independent
1= if both have reached the defrost end condition
2= if at least one has reached the defrost end condition
dF28 Defrost start end from analogue input
Probe that determines start/end of defrost
0= start and end with condensation temperature/pressure probe
1= start with evaporation pressure probe end with condensation temperature/pressure probe
