DEF Defrost
The heater defrost by time with temperature control (d0=4) activates the defrost output only if the
evaporator temperature (Sd) is less than the value of parameter dt1, and ends after the time defined by
dP1. This function is useful for energy saving and to prevent excessive temperatures on the evaporator.
5.3.1 Heater defrost (d0 = 0, 2, 4): duty cycle
The duty cycle refers to the default values of parameters F2 and F3. The electronic valve can be opened
to the initial value set for cP1 for a period equal to Pdd.
