SWITCHING ON THE PLUS 100 AB ELECTRONIC CONTROLLER
After wiring the electronic controller correctly, power up at 230 V AC; the display panel will
immediately emit a beep and all the segments and LEDs will come on simultaneously for a
few seconds.
COMPRESSOR ACTIVATION/DEACTIVATION CONDITIONS
The PLUS 100 controller activates the compressor when cold room temperature exceeds
setting+differential (r0); it deactivates the compressor when cold room temperature is
lower than the setting.
COOLING AND/OR FREEZING CYCLE ACTIVATION/DEACTIVATION CONDITIONS
To start a program press key 1.
Select a program (PR1....PR6) using the up / down keys.
Start the selected program by pressing key 1 for a few seconds. It is also possible to start
a program starting from stand-by mode.
To confirm the start of a cycle the warning/indicator LEDs come on and the program in use
is displayed. Compressor and fans function as per the settings in the individual programs.
The fans run continuously and the defrosts are inhibited. If key 1 is pressed briefly during
operation the remaining time appears momentarily on the display. At the end of the
program (time or temperature-based, indicated by a buzzer sounding for 30 seconds) the
controller carries out a defrost cycle (d4=0), after which it goes to storage mode and
controls the set room temperature.
To deactivate the cooling cycle manually press key 1 for a few seconds until the indicator
LED goes out.
