VAR.
MEANING
VALUES
DEFAULT
r0
Temperature differential
referring to the main SET-POINT.
0.2 ÷ 10.0°C
2.0°C
d0
Defrost interval
(hours)
0 ÷ 24 hours
0 = disabled
4
dd2
Delay to start defrosting on the second evaporator
.
Defrosting of the second evaporator starts dd2 seconds after
the end of defrosting 1. This avoids overloading of the
electrical system during defrosting if limited power is available.
With dd2=0 defrosts 1 and 2 start simultaneously. dd2 is
forced to 0 if d1 = 1 (cycle reversal defrost).
0 ÷ 10 sec
0 = simultaneous start
10 sec
d21
Evaporator 1 defrost end point
.
Defrosting 1 is not performed if the temperature read by the
defrosting probe 1 is higher than the value d21 (in case of a
faulty probe defrosting is performed on time).
-35 ÷ 45°C
15°C
d22
Evaporator 2 defrost end point
