If more details are required about parameters, refer to basic documentation P3174.
To re-load the factory settings for all parameters, set the parameter P71 to ON.
Restart the thermostat after reset. All LCD segments flash, indicating that the reset
is correct.
3 seconds later, the thermostat is ready for commissioning by qualified HVAC staff.
• When the thermostat is used with a compressor, adjust the minimum output on-
time (parameter P48) and off-time (parameter 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 min. 1 hour of
operation). To do this, change parameter P05.
• We recommend to review the setpoints and setpoint ranges (parameters
P08…P12) and change them as needed to achieve maximum comfort and save
energy.
The functional descriptions for the thermostat can be referred to basic
documentation (P3174).
