
Control ( Room / Extract / Supply ) – determines the current humidity sensor used to control
humidity.

PID–Regulation – the factory default values are: TI = 240 s, KP = 2, TD = 0 s.

PID– Supply – only applies when Setpoint = Room or Setpoint = Extract is set in the humidity
control configuration. The factory default values are: TI = 300 s, KP = 4, WPD =-2% .

Validity ( Regime / Always / Tempering ) – the system will only respond to a change in humidity
status if the unit is not in the Off state. The Regime has the following options:

Regime – system will respond to a change in humidity status only if the AC unit is in the
Comfort or Economy regime.

Always – system will respond to high humidity whenever the AC unit is not in the Off
state. That is, if the unit is in the Tempering , Comfort or Economy regime.

Tempering – system will only respond to high humidity when the unit is in the regime
Tempering .

HighHysteresis (5%) – value that determines the humidity control status. If the actual
humidity differs from the required humidity by this value, then it will activate to humidify or
dehumidify depending on the direction of the deviation.

High humidity status occurs if: Current humidity > required one ( Comfort / Economy ) +
HighHysteresis . With preset values, dehumidification starts at 55% humidity.

Low humidity state occurs if: Current humidity < required one ( Comfort / Economy ) –
HighHysteresis . With preset values, humidification starts at 45% humidity.

LowHysteresis (1%) – deviation, determining return from low or high humidity state. Its
function is as follows:

The High humidity state is terminated if: Current humidity < required one
( Comfort / Economy ) + LowHysteresis . With preset values, dehumidification is terminated
at humidity of 52%.

State Low humidity is terminated if: Current humidity > required one ( Comfort / Economy )
– LowHysteresis . With preset values, humidification is terminated at humidity of 52%.

HighLimitSupply – maximum humidity allowed in the supply air.

LowLimitSupply – minimum allowable supply air humidity.

ActiveDehumidification ( No / Cond / HPump / Water / All ) – specifies the cooling component that
will dehumidify the supply air. This component is controlled by the output of the PID humidity
