13. Controller

The unit is equipped with a temperature controller which regulates the function of the air-conditioning cycle.
At normal working conditions the display shows the temperature inside the enclosure. The cooling set point for
the interior of the enclosure (parameter St / St1) is pre-set at 35°C and can be adjusted between 20°C and
50°C.

To change the cooling set point St/St1:

1. Press ‘Set’ till St/St1 appears on the display

2. Press the Up/Down buttons to adjust the temperature setting

3. Press ‘Set’ to save the new setting

To change the heating set point St2 (units with internal heater only):

1. Press ‘Set’ till St1 appears on the display and release the button

2. Press again ‘Set’ till St2 appears on the display

3. Press the Up/Down buttons to adjust the temperature

4. Press set to save the new setting

Important Note: when changing settings ensure that: (St2 + 5K) < St1

The unit also has a potential free high temperature alarm relay (normally closed configuration) that is pre-set
to switch when the enclosure temperature exceeds 55°C. If necessary, the alarm relay configuration and the
set point can be changed via the controller’s parameters. Kindly contact your nearest service / sales partner
for further details on how to change these parameters.
