11 Options for ventilation mode

External control input
11.1.1 Description
With the external control input supplied as standard, the M-WRG-II unit has an additional
input terminal for 230 V AC (working voltage range: 85 V AC to 265 V AC / 50-60 Hz) to
which a switch, time switch, motion detector or similar may be connected.
The external control input is equipped with a time-delay relay that can be used to set a
switch-on delay and a run-on time:
— Switch-on delay:
the M-WRG-II unit does not start until the set time has elapsed.
— Run-on time:
the M-WRG-II unit does not switch to the previously active ventilation program until
the set time has elapsed.
Windowless rooms can be ventilated in accordance with DIN 18017-3 in combination with
the M-WRG-II O/NOF option, part no. 721004.
