Adjustable temperature fan controller with underpressure control. Let Rhino do the work! The RC-1 enables growers to acurately control the air exchange, set desired temperature and maintain negative pressure in the grow room.

Intake and extraction fans will run at maximum speed to quickly establish desired temperature, once reached the fans will drop to a minimum idle speed ensuring the room is adequately ventilated and preventing air leaks.


How to use:

1. Set the desired room temperature using the setting dial.

2. Once power is applied, the fan speeds can be set via the minimum speed dials; one speed control for each input (Intake/extraction)

3. If desired temperature is exceeded, the two fans will increase to full speed until the temperature falls back below the set point.

4. Fan speeds will then revert back to idling, controlling the negative pressure in the environment.
