61 Switch Sensor The Switch Sensor can perform either or both of the following functions: Switch detection: the ventilation system will perform a function when closing a (two-pole) dry contact. Suitable for toilet detection or overrule setting (only one function per switch sensor). Repeater: the switch sensor is ideally suited as a repeater (amplifier) to strengthen the signal in the event of RF communication problems. In that case the switch sensor must be positioned in such a way that the distance to be bridged and/or interference by obstacles is reduced. A switch sensor is easy to conceal thanks to its small size. Note: An external switch sensor is not required if a switch is connected to the onboard dry contact on the circuit board of the ‘master’ unit (DucoBox or IQ unit). Use a double-pole switch or relay and a 2 x 0.8 mm²cable for this.
