4.11  Switching on the AK-RC 

111 electronic controller

4.12  Cold/hot activation/

deactivation conditions

4.13  Manual defrosting 

activation/deactivation

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.

In cold mode (mOd=0)

, the 

AK-RC 111

 controller activates the compressor when cold room 

temperature exceeds s 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 4.16 for compressor 

activation/deactivation conditions.

In hot mode (mOd=1)

, the 

AK-RC 111

 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.

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).
