· 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.
· When the thermostat is used with a compressor, the minimum output on-time
(parameter P48) and off-time (parameter P49) for Y11/Y21 must be adjusted to
avoid damaging the compressor and shortening its life.
· 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.
