Product description
Introducing the GTE-1-60-DT, a grow room fan speed controller tailored for single-phase voltage-controllable motors. This innovative controller prioritizes precision by regulating fan speed based on measured temperature. When the ambient temperature falls below the setpoint, the fan remains idle. Upon surpassing the desired temperature, the exhaust fan accelerates to full speed until the temperature stabilizes. Set your ideal conditions in the 15 – 35 °C range for optimal produce growth.
Key features include a PT500 temperature probe input (pre-wired for DT version), potentiometers for temperature setpoints (15—35 °C), and minimum speed setting. Internal trimmer allows for maximum speed adjustment with adjustable hysteresis and proportional range. Housed in a reliable RABS V0 grey (RAL7035) enclosure, the GTE-1-60-DT offers , Schuko socket for motor connection, Euro plug for power supply and pre-wired temperature sensor and supply cable.
Technical specifications include a 230 VAC ±10 % / 50—60 Hz supply voltage, 6 A maximum motor current, Vmin adjustable (80—160 VAC) via potentiometer, and Vmax adjustable (170—230 VAC) via internal trimmer.

How does it work?
Fan speed is regulated based on the measured temperature. When the ambient temperature is lower than the temperature set point, the fan does not run. Once the measured temperature goes beyond the desired temperature set point, the (exhaust) fan accelerates towards full speed until the measured temperature is within range again. Once this happens, the fan speed will fall back until the idling speed is reached. After a while, the temperature will go out of bounds again and the fan will accelerate again. The desired temperature can be set in the range of 15 – 35 °C. This allows for selecting the optimal conditions for the growth of your produce.
Prewired and ready to use!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.
No configuration required
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.
Quality enclosure
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.
Triac fan speed control
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.
