Energysaver™ Sensamatic, fully automatic 150mm (6") axial kitchen fan, with integral microprocessor controlled contamination proof humidity sensor, together with 240V to 12V Switching Power Supply situated within the fan – no transformer required.
The energy efficient, ball bearing 12V DC motor only requires 8.4 watts of power when running, resulting in a long and trouble free operational life whilst reducing energy costs to the Resident.
Under the control of a microprocessor, the sensor monitors continuously the Relative Humidity (RH) in the room. If there is a sudden rise in RH the sensor anticipates hitting the set point and activates the fan before it is reached. After the fan has reduced the RH to about 5% below the preset set point, the fan switches off. When the fan is running under sensor and microprocessor control the L.E.D. flashes.
