Information about planning and application
2. Application:
The ventilator starts with a switch-on delay, but only if a movement is detected over a longer
period (e.g. 5 minutes). This is intended to prevent the ventilator being activated when someone
enters the toilet facility just briefly. If movement is detected over a longer period the ventilator
should continue for some time. The switch-on delay is based on the frequency of movement in
the first few minutes.
Parameter settings are made via the smartphone app "ABB Watchdog Remote control". Switch
there to HVAC mode. There into the "Switch-on delay/switch-off delay" function.
