SWITCHING ON THE ECP202 EXPERT ELECTRONIC CONTROLLER
After wiring the electronic controller correctly, power up at 230VAC; the display panel will
immediately emit a beep and all the LEDs will come on simultaneously for a few seconds.
COLD/HOT ACTIVATION/DEACTIVATION CONDITIONS
In cold mode (mOd=0), the ECP202 EXPERT 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 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 ACTIVATION/DEACTIVATION
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).
