
Regime – in this state the dampers can be controlled according to the preset
parameters for Comfort and Economy regimes or from a room unit or external
contact.

Humidity – dampers are controlled based on the set position for the
dehumidification condition.

AirQuality – dampers are controlled based on the set position for poor air quality.

Defrost – request for a minimum amount of fresh air is sent to the dampers because
a heating component is in defrost regime and at the same time the damper response
to defrost is enabled, parameter Defrost = Yes .

WaterHeating – minimum fresh air request is sent to the dampers because water
heating protection has occurred.

Err – all the dampers open 100% because one of the dampers is not in the expected
position. This is only true if the backward position of the dampers is monitored, and
every damper has its own control signal assigned at the control outputs from the
controller.

Damper (%) – required damper position calculated by the controller. The value is displayed
separately for every damper enabled in the configuration. This value should correspond to the
actual damper position if the damper control output is set correctly according to the wiring
diagram and servo drive type.

CtrlMixingComfort , MixingEconomy ( Fixed / Linearly /POL/ Setpoint / 2Setpoint ) – assuming the
unit includes a mixing damper, this parameter can be used to set the fresh air quantity control
to a fixed value, to a linearly varying value based on temperature, to a required supply air
temperature, or to a required preheat temperature, as part of a heating or cooling sequence,
according to the POL822 room unit, for every regime separately.

Fixed – dampers are set to a fixed value corresponding to the temperature period and the
selected regime.

SummerComfort (80%) – fixed position of the supply damper in the Comfort regime for
option CtrlMixingComfort =‘ Fixed ‘ .

SummerEconomy (50%) – fixed position of the inlet damper in the Comfort regime for
option MixingEconomy =‘ Fixed ‘.

WinterKomfort (80%) – fixed position of the inlet damper in the Economy regime for
option CtrlMixingComfort =‘ Fixed ‘.
