AZUR 100HT
The fan contains an integral humidity controller. In automatic mode the controller switches the fan on
at full speed when the room Relative Humidity (RH) reaches the set-point. The fan will continue to
run until the room RH falls below the set-point.
These fans also include a built in timer function. The timer can be activated by removing the Jumper
JP1, this will give the fan a fixed over run time of approx. 15 mins.

BEFORE ADJUSTING THE CONTROLLER, SWITCH OFF THE MAINS SUPPLY.
HUMIDISTAT SHOULD ONLY BE ADJUSTED BEFORE OR DURING INSTALLATION.
1.
Remove the fan grille. The controller is factory set to switch on at about 70% RH. The
humidity set point can be adjusted from 65-95%RH by altering the adjuster on the
