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

122°F.
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 131°F. 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.
