Switching on the OPTYMA
TM
Control single-phase
After wiring the electronic controller correctly,
connect 230 V a.c.; the display panel will
immediately emit a beep and all the LEDs will come
on simultaneously for a few seconds.
Compressor activation/deactivation conditions
The OPTYMA
TM
Control single-phase activates the
compressor when cold room temperature exceeds
differential (r0); it deactivates the
compressor when the cold room temperature is
lower than the setting.
Manual defrosting
To defrost just press the dedicated key (see page 8)
to activate the elements relay. Defrosting will not
take place if the end-of-defrost temperature setting
(d2) is lower than the temperature detected by the
evaporator sensor. Defrosting ends when the end-
of-defrost temperature (d2) or maximum defrost
time (d3) is reached.
When using data communication, the defrost cycle
can be started from the system unit.
