Commissioning
Set the thermostat application via the DIP switches before snapping the front panel onto the
mounting base.
After power is applied, the thermostat resets all LCD segments light up indicating that reset-
ting was correct. After reset, which takes about 3 seconds, the thermostat is ready for com-
missioning by qualified HVAC staff.
The control parameters of the thermostat can be set to ensure optimum performance of the
entire system (see basic documentation A6V12166490).
Note
After power failure, the thermostat restarts in the same mode as before, Comfort or Protec-
tion (depends on P27).
The control sequence may need to be set via parameter P01 depending on the application.
The factory setting for the 2-pipe application is “Cooling only”; and “Heating and cooling” for
the 4-pipe application.
Compressor-based application
When the thermostat is used with a compressor, adjust the minimum output On-time (P48)
and Off-time (P49) for Y1/Y2 to avoid damaging the compressor or shortening its life due to
frequent switching.
Recalibrate the temperature sensor if the room temperature displayed on the thermostat
does not match the room temperature measured (after minimum 1 hour of operation). To do
this, change P05.
We recommend reviewing the setpoints and setpoint ranges (P08…P12) and changing them
as needed to achieve maximum comfort and save energy.
