7.23 Condensate drain pan heater
This function heats the condensate drained during defrosting to prevent the drain line from freezing.
Par. Description Def Min Max UOM User User terminal
DOP Assign drain heater digital output - see DOA ... 0 6 - S NO
rOP Drain heater digital output logic - see rOA 0 0 1 - S NO
dHA Condensate drain heater activation time before defrosting 3 0 120 min S NO
dHE Condensate drain heater activation time after
defrost
3 1 120 min S NO
If condensate drain heating is confi gured, the output is activated for the time set by parameter dHA before defrosting, and re-
mains active for a time set by parameter dHE after defrosting.
7.24 Anti-heating
This function keeps the light and AUX outputs deactivated until the control temperature falls below St+Hdh when the following
conditions occur:
• controller powered on;
• switching from Off to On;
• after resetting alarms HI, IA, dA, CHt, rE.

St Temperature control set point 50/122 r1 r2 °C/°F U YES
7.25 High and low voltage protection (HLVP)
The high and low power voltage protection (HLVP) feature is disabled by default. Carefully read the following instructions care-
fully for correct setup. Some iJW models feature protection against high and low power supply voltages, allowing the compres-
sor to operate only at voltages within the operating limits. This function stops the compressor if the mains voltage is outside of a
range specifi ed by parameters uHo and uLo. The compressor is switched off after a delay that can be set by parameter ucd. The
compressor starts again when the voltage returns within the limits set by parameters uHI and uLI.

c2 Min compressor OFF time 0 0 15 min S NO

Notice: the compressor protection times c1 and
c3 are ignored when the high or low voltage condi-
tions occur, while c2 is always observed.
Caution:
• this function cannot be considered a compressor
safety function;
• operation of the controller outside of the rated oper-
ating voltage range described in the technical speci-
fi cations is the customer’s responsibility.
