This stepped fan speed voltage controller with temperature override is another great product from GSE that will help you maintain balance and harmony in your grow room environment.
Designed to closely and quietly manage fans, the voltage controller aims to maintain low operating speeds to avoid having an impact upon your plants and fortunately doesn’t produce any humming noises – unlike competing resistive models.
After selecting your desired temperature on the left dial and the hysteresis on the right dial, the GSE Step Transformer then monitors the grow room conditions according to these settings. When necessary, it will automatically begin moving through 6 progressively more powerful fan speed options – with the hysteresis defining the temperature range – until the preferred climate is re-established.
The GSE Step Transformer has a durable, water resistant cover and the 2.5A capacity is capable of accommodating most of the fans available through GroWell. To control multiple fans, an extension needs to be plugged into the unit – just take care not to exceed the 2.5A allowance between your fans.
