  • Product description

    Electronic temperature-controlled fan speed controller | 15-35°C | 6A | 230VAC | with PT500 sensor | Schuko socket | IP54 | Sentera Controls | GTE-1-60-DT

    GTE-1-60-DT – a Sentera Controls electronic temperature-controlled fan speed controller for AC motors fed with single-phase 230 VAC up to 6 A. Plug-in version: the kit includes a PT500 temperature sensor and a power cable with a Euro plug; the fan is connected to the Schuko socket. Temperature setting 15–35 °C.

    Key idea:
    You plug it into a socket, insert the fan plug and set the temperature – as the temperature rises, the fan speeds up by itself. Suitable where simple, quick-to-install temperature-based ventilation is needed without a control panel and an automation design. The 15–35 °C setting range is suited to typical temperatures in greenhouses, livestock buildings and workshops.

    Temperature setpoint

    Operating principle

    The controller is powered via a cable with a Euro plug (230 VAC ±10 %, 50–60 Hz), the fan plugs into the integrated Schuko socket, and the PT500 sensor (included) connects to the GND and T (TEMP.) terminals. The unregulated 230 VAC output L1 (up to 2 A) can power a damper actuator or another 230 V device.

    The controller electronically varies the motor voltage between Vmin (80–160 VAC, external potentiometer) and Vmax (170–230 VAC, internal trimmer). While the temperature is below the setpoint (15–35 °C by potentiometer), the fan runs at minimum speed or, with the OFF level enabled by jumper JP5, switches off; above the setpoint, the speed increases within a proportional band of 2, 4 (factory), 6 or 8 °C (JP1/JP2), with a hysteresis of 0.5, 1, 2 (factory) or 3 °C (JP3/JP4).

    Result – the fan runs only as much as the temperature requires, and the controller is installed without a panel or electrical design. Engineer's note: when voltage is reduced on an AC induction motor, rotor losses increase, so the savings are smaller than with an EC fan or a frequency converter; if the motor hums at low speed, choose a GTH series transformer speed controller with sinusoidal voltage.

    Benefits GTE-1-60-DT?
    Temperature-based ventilation without a control panel and complicated installation: the sensor and cable are already included, and the fan is connected by a plug.

    Main functions

    • Plug-in connection – Euro plug for power, Schuko socket for the fan, PT500 sensor included in the kit.
    • Speed according to temperature – as the temperature rises above the setpoint, the fan speeds up smoothly.
    • Adjustable proportional band and hysteresis – jumpers adjust how quickly the fan responds to temperature.
    • Min. and max. speed – Vmin 80–160 VAC with a potentiometer, Vmax 170–230 VAC with a trimmer – speed and noise are limited to suit the site.
    • OFF level – optionally, the fan switches off when the temperature is below the setpoint.
    • Unregulated 230 V output (up to 2 A) – for a damper actuator or another 230 V device.

    Where is it used?

    • Greenhouses
    • Ventilation systems with temperature control
    • Livestock and poultry housing
    • Workshops, warehouses, technical rooms
    • Temporary or mobile ventilation where the fan is connected with a plug
    • Boiler rooms, server rooms and other warmer rooms (setting 15–35 °C)

    On-demand operation

    For the caretaker of boiler rooms and technical rooms.
    The plug-in controller with a PT500 is switched on without a panel and controls overheating within the 15–35 °C range.
    For poultry house and livestock farm owners.
    The fan speeds up as the temperature rises, while the minimum speed maintains continuous ventilation.
    For mobile fan rental and installation companies.
    A Euro plug and Schuko socket allow the controller to be moved between sites.

    Practical application

    If a 4 A single-phase extract fan in a boiler room has to speed up when the temperature rises above 25 °C, then set the GTE-1-60-DT to 25 °C with the factory 4 °C proportional band, and the fan will run at full speed at around 29 °C and at minimum speed below 25 °C.

    Application guide: how it is used in practice

    Typical GTE-1-60-DT applications:

    Site What is connected Result Installer's note
    Greenhouse Fan → Schuko socket; PT500 → in the plant zone As the temperature rises, the fan speeds up; when it is cooler, it runs at minimum speed or switches off Install the sensor in shade, not in direct sunlight
    Poultry house / livestock room Extract fan up to 6 A Temperature-based ventilation is maintained, with the minimum air exchange level held at Vmin Leave the OFF level (JP5) disabled if continuous minimum ventilation is required
    Fan with air damper Damper actuator 230 VAC → L1 The damper is powered together with the controller L1 load – up to 2 A
    Workshops, warehouse Extract fan On a hot day extraction increases Increase the proportional band (6–8 °C) if the speed changes too abruptly
    Temporary site Euro plug → 230 V socket The device is easy to move to another location For indoor use only

    How to select the controller current

    Rated current of the motor(s) Recommended model
    up to 6 A · setpoint 15–35 °C · plug-in, with PT500 GTE-1-60-DT (6 A) ← this model
    up to 6 A · setpoint 15–35 °C · Modbus RTU GTE-1-60-DM (6 A)
    up to 6 A · setpoint 5–35 °C · plug-in, with PT500 GTE21-60-DT (6 A)
    up to 6 A · setpoint 5–35 °C · Modbus RTU GTE21-60-DM (6 A)
    Rule: the controller's max. current ≥ the rated current of the motor (or the sum of several motors) from the motor nameplate. The starting current has already been taken into account by the manufacturer, no extra margin is needed. When connecting several fans – of the same type, AC motors with voltage control – add up their rated currents. All GTE models are 6 A; choose by temperature range and version (DT / DM).
    When to choose another solution: for a different temperature setting range (5–35 °C) – GTE21-60-DT; with Modbus RTU and terminal connection – GTE-1-60-DM; sinusoidal voltage and a water heater valve – transformer GTH-1 / GTH21 series; electric heater – GTTE1 series; control by a 0-10 VDC signal – EVS-1 series; for EC fans – EC controllers with a 0-10 VDC output.

    Pros

    • Plug-in connection, PT500 sensor included
    • Automatic speed control according to temperature
    • Adjustable proportional band and hysteresis
    • Min. and max. speed are set
    • Unregulated 230 V output (2 A)
    • IP54 enclosure

    Cons / limitations

    • No Modbus RTU – for that choose GTE-1-60-DM
    • Single-phase voltage-controllable AC motors only; not suitable for EC fans
    • Controlled only by ventilation logic – speed increases as temperature rises
    • Indoor use only, operating environment 0…+40 °C; no TK terminals or alarm output
    • Setpoint only from 15 °C – for cooler rooms choose GTE21-60-DT (5–35 °C)

    Safety and installation notes

    • Installation and connection must be carried out by a qualified electrician with the power disconnected.
    • Connect only to an earthed 230 VAC socket.
    • Check that the motor is suitable for voltage control and that its (or several motors') rated current does not exceed 6 A.
    • The unregulated L1 output load – no more than 2 A.
    • Intended for indoor use only: 0…+40 °C, < 95 % rH non-condensing.

    Quick selection guide

    6 A
    230 VAC
    15–35 °C
    PT500 included
    IP54
    Suitable when you need:
    • for temperature-based ventilation with an AC fan up to 6 A;
    • for greenhouse and farm building microclimate control;
    • for quick installation without a control panel – with a plug;
    Check before use:
    • the motor rated current and whether it is voltage-controllable;
    • whether the temperature setting range of 15–35 °C is suitable;
    • whether the fan has a Schuko plug;
    Important reminder: The GTE-1-60-DT does not control EC fans, three-phase motors and heaters – it only changes the fan speed according to temperature.
