In case of fault in the thermostat probe the start and stop of the compressor are timed through parameters Con and CoF. The defrost interval depends on the presence of the RTC optional.
Ld6, during workdays, and in Sd Sd6 during holidays. At the end of defrost dripping time is started, its length is set in the Fdt parameter. An additional parameter FSt provides the setting of temperature, detected by the evaporator probe, above which the fans are always OFF.
This is used to make sure circulation of air only if his temperature is lower than set in FSt. If the temperature difference between the evaporator and the room probes is higher than the value set in the FCt parameter the fans are switched on.
When the compressor is stopped the fans go on working for the Fon time. In the following paragraph the possible settings are explaided. ACH: kind of regulation for the auxiliary relay: Ht: heating; cL: cooling; - SAA: set point for auxiliary relay; - SHy: differential for auxiliary relay; - ArP: probe for auxiliary relay; - Sdd: auxiliary output off during defrost.
The auxiliary relay can be switched on also by using the AUX button. Both the compressors are switched off at the same time. It is activated every time an alarm happens. DEF To start a manual defrost. UP To see the max stored temperature; in programming mode it browses the parameter codes or increases the displayed value. DOWN To see the min stored temperature; in programming mode it browses the parameter codes or decreases the displayed value.
Check the supply voltage is correct before connecting the instrument. The instrument must not be opened. In case of applications in industrial environments, the use of mains filters our mod. They are provided with 3 relay outputs to control compressor, defrost - which can be either electrical or hot gas - and the lights. They are also provided with 2 NTC or PTC probe inputs, one for temperature control, one to control the defrost end temperature of the evaporator. There are 1 digital inputs free contact configurable by parameter. An output allows the user to programme the parameter list with the "Hot Key".
