SWITCHING ON THE ECP202 EXPERT D7.5 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 LEDs will come on simultaneously for a few seconds.
COMPRESSOR ACTIVATION/DEACTIVATION CONDITIONS
In cold mode (mOd=0),
the
ECP202 EXPERT D7.5
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.
If Pump-Down function is selected (Parameter AU1/AU2 = 4/-4), see chapter 5.16 for
compressor activation/deactivation conditions.
In hot mode (mOd=1),
the
ECP202 EXPERT D7.5
controller activates the heat output
(COMPR output) when cold room temperature drops below setting-differential (r0); it
deactivates the heat output (COMPR output) when cold room temperature is higher than
the setting.
MANUAL DEFROSTING
To defrost just press the dedicated key (see section 5.2) 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, or due to forced manual
defrost termination (end of defrost button or digital input).
