Mains Input - Xpelair XHR150PC Installation Instructions Manual

Isolating Transformer (Humidity sensor unit).
The humidistat monitors the humidity in the room and automatically switches the ventilator from continuous trickle
speed to boost if the humidity exceeds the set point e.g. when using the shower, cooking or doing the laundry.
The humidity level can be adjusted by turning the thumbwheel (as shown on page 2). We recommend that it is initially
set to number 6 on the scale, which is suitable for most locations. Turning the thumbwheel clockwise decreases the
sensitivity (fan in boost for shorter time) and anti-clockwise increases the sensitivity (fan in boost for longer time).
To prevent tampering with the setting after installation, the thumbwheel can be removed by carefully pulling gently
upwards. A blanking plate is supplied to seal the hole previously occupied by the thumbwheel.
If installed in a shower or bathroom the transformer/humidistat must be out of reach of anyone using a bath or shower.
We strongly recommend installation by a competent electrician.
