5. EXTERNAL CONTROL INPUTS FOR ELECTRONIC CONTROL SYSTEM
• External input for moisture control
To quickly remove moisture when ventilating rooms with a high moisture load, e.g. baths, showers, the output of the Fox
up ventilation units can be increased depending on the moisture via an external hygrostat (= moisture-dependent switch).
The switching point (= moisture level) for increasing the power is set on the hygrostat. If the set moisture level (recommended settings,
summer: 65-80% RH, winter: 55-65% RH) is exceeded, the hygrostat activates power stage 3 in the ventilation unit.
Hygrostats are connected to contacts 1 and 2 of the “external inputs” connector on the electronic control system of the ventilation unit as
shown in the connection diagram on page 9.
External moisture mode is displayed on the electronic control system’s control
panel by the flashing of the “power level 3” signal lamp.
If the power level is not changed manually on the control panel, the unit will
continue to operate at the last active power stage after the external contact is
switched off again.
Power stage 3 of the externally activated moisture mode can be reduced to power
stage 2 or 1 using the electronic control system’s control panel. To ensure that the
increased humidity is reduced, it is not possible to switch off the unit or return it to
the “minimum ventilation” power stage.
• “Unit off” external input:
To prevent moisture damage in your rooms, Fox up ventilation units have been designed for continuous ventilation. If the ventilation nevert-
heless has to be interrupted* at certain times, the ventilation unit can be switched off via an external switch / time switch.
The switch / time switch is connected to contacts 3 and 4 of the “external inputs” connector on the electronic control system of the ventila-
tion unit as shown in the connection diagram on page 9.
A ventilation unit switched off externally* is indicated on the control panel of the
electronic control system by the flashing of the “OFF” signal lamp.
If the power level is not changed manually on the control panel, the unit will
continue to operate at the last active power stage after the external contact is
switched on again.
A ventilation unit switched off externally* can be switched back on by pressing the
“power level up” key on the control panel of the electronic control system.
* The external switching off of the ventilation unit depends on the “minimum
ventilation” jumper setting (see page 17). If minimum ventilation is activated,
the operation of the system is not interrupted when switched off externally, but
reduced to minimum ventilation. Minimum ventilation is displayed on the remote
control by the pulsing of the “OFF” signal lamp.
