5.11 Switching on the
AK-RC 113
electronic controller
5.12 Cold/hot activation/
deactivation conditions
5.13 Manual defrost activation
/ deactivation
After completing the wiring of the electrical panel, power it by operating the main switch;
immediately the electrical panel will emit a sound for a few seconds and at the same time all the LEDs
will light up on the display.
In cold mode (mOd=0)
, the
AK-RC 113
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 5.16 for compressor
activation/deactivation conditions.
In hot mode (mOd=1)
, the
AK-RC 113
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 activate the defrost, simply press the dedicated key (see Chapter 5.2) in this way the resistance
relay is activated. Defrost is not activated if the set end defrost temperature (d2) is lower than the
temperature detected by the evaporator probe. Defrost will end when the end defrost temperature
(d2) is reached or for maximum defrost duration (d3) or for manual defrosting end forcing (defrost end
button or digital input).

resistances
5.15 Hot gas defrost
5.16 Pump down function
5.17 Password function
Set the parameter
d1=2
for the management of the resistance defrost with time limit. During
defrosting, the defrost relay is activated if the temperature read by the defrost probe is less than
d2
.
The defrost phase lasts
d3
minutes, regardless of the state of the relay. This allows a better defrosting
of the evaporator with a consequent energy saving.
Warning: do not set d1 = 1 in this type of electrical panel.
The hot gas defrost is not available for this type of electrical panel.
Selection of PUMP DOWN functioning mode for the compressor working on X1 terminal block,
changing the selection connection as indicated in the wiring diagram.
Warning:
Parameters AU1 / AU2 must never be set to 4 / -4 because the PUMP DOWN function is
made in electromechanical inside the electrical panel.
When parameter PA is setting with value different to 0 the protection function is activated.
See parameter P1 for the different protection.
When PA is setting the protection start after two minutes of inactivity. On display appear 000.
With up/down modify the number, with set key confirm it.
Use universal number 100 if you don’t remember the password.
