5 Ont Ont: On time (compressor). Compressor activation time in the event of faulty probe.
OFt: OFF time (compressor). Compressor stop time in the event of a faulty probe.
If Ont=0, the compressor is off.
6 OFt
If Ont≠0 and OFt=0, the compressor is always on.
If Ont≠0 and OFt≠0, the compressor functions in duty cycle mode per Ont/OFt.
Delay (after power) OFF. Delay after switch off; the indicated time must elapse
7 dOF
between switch-off of the compressor relay and the successive switch-on.
Delay Output (from power) On. Delay time in activating the outputs after switch-on
8 OdO
of the controller or after a power failure.
Defrost type:0 = electric defrost;
9 dty 1 = reverse cycle defrost (hot gas);
2 = Free defrost (compressor hot).
10 Defrost interval time. Interval between the start of two successive defrost
dit
operations.
Defrost Counting type. Selection of count mode for the defrost interval.
0 = compressor operating hours;
11 dCt
1= fixed time interval;
2 = compressor stop hours.
12 dOH Defrost offset hour. Start-of-defrost delay time from startup of controller.
13
dEt Defrost endurance time. Defrost time-out; dEt=0, defrost is disabled.
14
H42 Whether to enable evaporator sensor: y=yes; n=no
15 dSt Defrost stop temperature
Defrost (at) Power On. Determines if at the start-up the controller must enter
16 dPO defrosting (if the temperature measured allows this operation).
y = yes; n = no.
17 FSt Fan stop temperature
18 FAd Fan activation differential
19 Fdt Fan delay time. Delay time in activating fans after a defrost operation.
20
dt Drainage time. Dripping time
Defrost fan disable. Allows to select the evaporator probes exclusion during defrost.
