After applying power, the thermostat makes a reset during which all LCD segments
flash, indicating that the reset has been correctly made. This takes about 3 seconds.
Then, the thermostat is ready for commissioning by qualified HVAC staff.
The control parameters of the thermostat can be set to ensure optimum performance of
the entire system (please also refer to “

Set the heating/cooling mode via parameter P22 depending on the application.
Factory setting is “Manual heat/cool changeover”. Set P22 accordingly in ”Cooling
