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 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 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).
8 = Night mode digital input
(energy saving, N.O.)
7 = Stop defrosting remotely (N.O.)
(reads rising edge of impulse)
6 = Start defrosting remotely (N.O.)
(reads rising edge of impulse)
5 = Stand-by remotely (N.O.) (In
order to indicate Stand-By
mode, the display shows 'In5'
alternating with the current
view)
