To adapt the controller to your system and optimize the control performance, a number of
control parameters can be adjusted. This can also be made during operation without
opening the controller.
Control sequence
Recalibrating the sensor
Energy saving mode
If you want to change the factory-set temperature setpoints (15 °C for heating
and 30 °C for cooling), the parameter P11 and P12 need to be adjusted.
Important:
The setpoint of energy saving mode can be set to
OFF
; this
means that the controller is then not active!
Risk of frost,
i.e. no protective

. Depending on the selected application, the relevant modes are
available and can be adjusted by commissioning parameter P01 if needed.
The factory setting for 2-pipe and single duct application is “C
ooling only”
,
and for 4 pipe application “Heating and Cooling”
If the room temperature displayed by the controller does not agree with the
temperature effectively measured, the temperature sensor can be
recalibrated. With parameter P05 the temperature can be adjusted by + or –
0.5 °C up to a maximum of + / - 3 °C.
