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 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 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).

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.

(like In1)

0 = disabled

1 = enabled

0 = Cold call

1 = Hot call

(with mOd=1 the defrosts and

the fan block Fst are excluded)

0 = only display set point

1 = display set point, AUX,

light access

2 = access in programming

not permitted

3 = access in second level

programming not permitted

0...999

0 = not active
