Humidity Set-Point Adjustment.
The Fan’s Humidity Set-Point is factory set to switch the fan on at approximately 72%RH. The sensitivity may be
adjusted at installation from 65%RH-90%RH, by altering the adjuster on the Fan PCB.
Before adjusting the Set-Point, switch off the Mains Supply.
1. Remove the Indoor Grille [A]. Loosen the screw (top middle) of the Grille, to release front grille gently lever the
Grille downwards away from the Inner Cover [B].
2. Remove Inner Cover [B]. Loosen the screw (bottom middle) and release the inner grille gently from the Base
Housing [D].
3. To LOWER the Set-Point, turn the adjuster ANTI-CLOCKWISE. This makes the fan more sensitive to RH%, i.e.
the fan will come on at a lower RH%.
4. To RAISE the Set-Point, turn the adjuster CLOCKWISE. This makes the fan less sensitive to RH%,
i.e. the fan will come on at a higher RH%.
5. Replace the Inner Cover and Indoor Grille.
6. Reconnect the mains supply.
(If remote override is required refer to Fig 6 for installation. The remote switch will switch between automatic
humidity control and manual override. Ignore the timer control potentiometer in the diagram)

Humidity and Time Set-Point Adjustment.
The fan’s Humidity Set-Point is factory set to switch the fan on at approximately 72%RH. The sensitivity may be
adjusted from 65%RH - 90%RH, by altering the adjuster on the Fan PCB.
The overrun Time period is factory set to approximately 15 minutes. The overrun time period may be adjusted from
5-30 minutes, by altering the adjuster on the Fan PCB.
Before adjusting the Set-Point, switch off the Mains Supply.
1. Remove the Indoor Grille [A]. Loosen the screw (top middle) of the Grille, to release front grille gently lever the
Grille downwards away from the Inner Cover [B].
2. Remove Inner Cover [B]. Loosen the screw (bottom middle) and release the inner grille gently from the Base
Housing [D].
3. To LOWER the Set-Point/ operating time, turn the indicated adjuster ANTI-CLOCKWISE. This makes the fan
more sensitive to RH%, i.e. the fan will come on at a lower RH% or will reduce the overrun time.
4. To RAISE the Set-Point/ operating time, turn the adjuster CLOCKWISE. This makes the fan less sensitive to
RH%, i.e. the fan will come on at a higher RH% or will increase the overrun time.
5. Replace the Inner Cover and Indoor Grille.
6. Reconnect the mains supply.
