FUNCTIONS CONTROLLED BY THE VISION 2PLT
-
Display and adjustment of room temperature.
-
Display of evaporator 1 and evaporator 2 temperature.
-
Display of ambient 1 and ambient 2 temperature.
-
System control activation/deactivation.
-
Operation with single set-point and control of two motor condensing units with delays
between the two parameter-set starts.
-
Compressor rotation (to make wear uniform).
-
Operation with double set point for gradual application of refrigerating power.
-
System warnings (ambient ½ temperature sensor error, min-max temperature alarms,
compressor 1 and compressor 2 safety devices, man in room alarm, different probe
values alarm).
-
Evaporator 1 and evaporator 2 fan control.
-
Automatic/manual defrost control (static, with elements, with elements with temperature
control, cycle inversion and cycle inversion with basin).
-
Clock for real time clock defrosting of the two evaporators simultaneously or separately
(even where defrosting cycle is set simultaneously the end-of-defrost temperature and
control of fan start delay on the two evaporators are independent).
-
Room light can be switched on with on-panel key or door switch.
-
Alarm relay.
-
Management twin probe security environment. If the room sensor 1 is faulty alarm is
signaled and the reference sensor control changes automatically.
-
Functionality password to control access to different levels of programming.
-
