The Cli-mate AIRFAN 3-Speed Hybrid EXCRH3 is an advanced EC fan controller that automatically adjusts fan speed based on temperature. The device works with fans that use 0–10 V control and makes it much easier to maintain the right conditions in a grow box or grow room.
The controller comes with a digital remote featuring a backlit LED display and an external temperature sensor with a 4-meter cable. The user can set the ventilation parameters, and the controller automatically adjusts the operation of a compatible EC fan.
Temperature is one of the most important parameters affecting conditions within a closed growing space. The EXCRH3 uses an external temperature sensor to monitor conditions at a selected location.
Once a threshold value is set, the controller can adjust the fan’s operation accordingly. When more intensive air exchange is needed, the fan speed is increased. This reduces the need to manually change ventilation settings throughout the day.
The Cli-mate AIRFAN EXCRH3 is designed to work with fans equipped with EC motors that support a 0–10 V control signal. Electronic control allows you to adjust the ventilation intensity to current demand.
The ability to set a minimum fan speed ensures that basic air exchange is maintained even when the unit’s full capacity is not required.
The controller allows you to tailor the operation of the ventilation system to your needs. Both automatic and manual operating modes are available.
In automatic mode, control is based on temperature readings and selected settings. Manual mode allows you to directly set the fan’s operation when automatic control is not needed.
The controller is operated using a digital remote control with a backlit LED screen. It allows you to conveniently adjust settings without needing direct access to the fan.
This solution is particularly practical in larger grow boxes and setups where the fan is located high up or has been mounted in a hard-to-reach place.
The kit includes a temperature sensor equipped with a 4-meter cable. This allows you to place the probe in a location where the temperature measurement is most representative of the controlled space.
Proper placement of the sensor enables the controller to respond to conditions within the growing area, rather than solely in the immediate vicinity of the ventilation equipment.
The EXCRH3 is a particularly good complement to compatible AIRFAN box fans. It allows you to create an automatically regulated air exchange system without the need to constantly adjust the fan speed manually.
