Grow room air extraction | 15-35 °C | Prewired | 6 Amps
Product description
This device provides precise temperature-based fan speed control for single-phase motors with a maximum current of 6 A. The controller automatically adjusts the fan speed to maintain a set temperature between 15 and 35 °C. The motor idles when the temperature is below the setpoint and runs at full speed when it is above.
The controller uses a PT500 temperature probe input, which comes pre-wired in the DT version. You can set the desired temperature and minimum speed using potentiometers, while an internal trimmer allows for fine-tuning the maximum speed, hysteresis, and proportional range.
The controller has an IP54 enclosure with Schuko and Euro plugs and pre-wired cables for easy installation. It operates on a 230 VAC supply, with both the minimum (80-160 VAC) and maximum (170-230 VAC) voltage being adjustable.

How Is Fan Speed Controlled Based on Temperature?
What Are the Plug & Play Features of This AC Fan Speed Controller?This AC fan speed controller is 100 % ‘plug & play’. It works by simply plugging it into the mains network via a standard Schuko socket. It does not require any configuration or wiring. The PT500 temperature probe (4 m cable length) and the power supply cable (1,5 m length) are prewired. The exhaust fan can be connected via the Schuko socket as well. Consult the datasheet or mounting instructions to learn how to adjust the hysteresis and ranges.
How Can I Adjust Temperature and Motor Speed Settings?
Via the two built-in potentiometers, it is possible to set the desired temperature and adjust the minimum motor speed. These potentiometers can be controlled by turning a rotary knob. The temperature setpoint can be set in the range of 15 – 35 °C. Motor speed is controlled by controlling the motor voltage. This fan speed controller therefore only works for voltage controllable motors. If there is uncertainty whether your motor is voltage controllable, please check with your motor manufacturer. The minimum motor voltage can be set in the range of 80 – 160 VAC. The maximum motor voltage can be set in the range of 170 – 230 VAC through an internal trimmer.
What Are the Enclosure's Safety and Durability Features?
This controller is the result of many years of experience in growing room air extraction combined with innovative electronics technology. This device is extremely reliable and safe. The enclosure is made of high-quality r-ABS VO (UL94) plastic. This material is flame extinguishing in case of fire. It is very tough and it offers good protection against impacts. The enclosure offers IP54 protection against the ingress of dust, dirt and water. However, to guarantee a good service life, it should be installed in a place away from direct sunlight. This fan speed controller is suited for wall mounting.
How Does Triac Technology Affect Fan Speed Regulation and Motor Noise?
This fan speed controller uses Triac technology to regulate fan speed. Fan speed controllers with Triac technology regulate the motor continuously variable. The phase angle control of the Triacs ensure the fan speed controller operates completely silently. The drawback is that the motor may make some noise at low speeds. This is because the AC motor voltage will not have a perfect sinusoidal shape. To prevent motor noise, it is possible to increase the minimum motor voltage.
