  • The Twincontroller MK2 can also be used to just controle an extractor fan, to do so you only have to plug the extractor fan in the "FAN AIR OUT" power socket. The Twin Controller MK2 will drive the fan and will continuously seek the best fan speed to maintain the desired temperature.

When connecting the Twincontroller to the mains, it will start in a scanning mode. During this 5 minute periode it speed up and slow down attempting to find the perfect speed for the fans. After the scan process, the Twincontroller will always know the perfect speed to drive the fans for a constant temperature.

Note: Too slowly rotating fans can create a lot of noice and can also caus failure of the fans. So make sure that the minimum level is not set too low.
