Application 

A continuously running, low energy, ultra quiet extract fans for use in kitchens, utility rooms, bathrooms, shower rooms, en-suites and toilets.

The fan is equipped with a humidity sensor, whose threshold is adjustable from 50% to 95% Relative Humidity via a dedicated trimmer, and with a timer which is adjustable from 0 to approx. 30 minutes via a dedicated trimmer. The fan runs continuously at selected trickle speed (set by the jumper switch combination) and increases its speed when the percentage of Relative Humidity exceeds the settable threshold, the fan can also be boosted with a dedicated ON/OFF switch (or PIR, CO2 sensor) or with a light switch. Trickle speed can be set to off. To deactivate the humidistat function, turn the trimmer HY completely clockwise.

Automatic humidistat operation: when the percentage of Relative Humidity exceeds the settable threshold, fan speed automatically increases to “comfort boost” speed, (intermediate between the selected trickle speed and the boost speed). When the percentage of Relative Humidity goes below the threshold, the fan continues to function at “comfort boost” speed for a factory set period of time then returns to selected trickle speed.

Operation with external switch: When the external switch is turned on, the fan is boosted. After the external switch is turned off, the fan continues to run at boost speed for a settable period of time, then it returns to selected trickle speed (or to “comfort boost” speed in case automatic humidistat operation is on). The front cover LED indicates when the external switch is on. The over-run timer function is activated only if the external switch has been on for at least 60 seconds.
