The control parameters of the controller can be set to ensure optimum
performance of the entire system (see “Set control parameters”).
·
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 controller 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
controller does not match the room temperature measured. 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
