Output Configuration
Two devices may be controlled. CP10 decides if control mode is humidify or dehumidify modes are enabled. In case dual
control mode is disabled CP11 activates fan control on the available output.

Fan delay
The fan output may be activated with parameter CP11. CP10 must be ≠ 0 for the fan output to function.
Once there is an output demand, the humidistat will first activate the fan, wait the required start delay time (CP12) and then
activate the control output. This will ensure stable air for humidification or de-humidification.
The control output will be switched off when the setpoint is reached. The fan keeps running until stop delay (CP13) has
expired. This will ensure that no left over humidity remains in the humidify- / de-humidify device or its ducts.

Averaging function of input signal:
The averaging function is used to prevent unwanted fluctuation of sensor signals. The controller measures every second the
signal inputs. The input signal is built over a number of measured values. Select how many values should be used to calculate
the averaging signal. Control speed will slow down when a large number of samples are used for an averaging signal. This
should be taken into account when defining the control parameters.
