Greenhouse Temperature Controller
Greenhouse temperature controllers are the core operational equipment in modern greenhouse environmental control systems. By integrating with sensors for temperature, humidity, CO₂, and other parameters, they automatically regulate vents based on preset conditions, ensuring precise control of indoor climate.
It can prevents excessive heat and humidity, enhances ventilation, reduces the risk of pests and diseases, and allows flexible adjustment of ventilation strategies according to crop growth stages. It minimizes the need for manual intervention, improving overall management efficiency.
Introduction
Greenhouse Temperature Controller are automated devices used for environmental control in greenhouses. They intelligently control the opening and closing of vents based on parameters such as temperature and humidity, improving air circulation and environmental stability within the greenhouse, and reducing manual labor and energy waste.

Structure of Greenhouse Temperature Controller
Wiring Section
- Aviation Connector Section: Default connection to temperature sensor. Optional temperature/humidity sensor. Optional rain/snow sensor.
- Power and Control Section: The controller supports both 12V and 24VDC power supplies. Select the appropriate power supply based on the chosen roller. For example, if using a 12V 50W roller, select a 12V power adapter rated at 60W or higher; if using a 24V 100W roller, select a 24V power adapter rated between 100W and 130W.
Indicator light section
- Power indicator : Remains lit when the controller is powered on.
- Network indicator : Remains lit when the controller is successfully connected to the server; turns off if the connection fails. Flashes when data is being exchanged between the controller and server.
- Button indicator : Flashes once when a button is pressed and held; remains off by default.
LCD section
- Percentage of vent opening. 0% indicates the vent is fully closed, while 100% indicates the vent is fully open.
- Overlap position. Indicates the current overlap position of the greenhouse, as shown in the figure, where the vent reaches the overlap position at 15% opening.
- Parameter display. Shows the current greenhouse temperature. If equipped with a temperature and humidity sensor, it cycles through displaying the current greenhouse temperature and humidity every 5 seconds. If the sensor malfunctions, an asteriskis displayed.
- Operating mode display. Shows the current operating mode, which includes: Manual, 3-stage segmented, 5-stage segmented, 3-stage smart, 5-stage smart, and One-touch dehumidification.
- Time display. Shows the current time (24-hour format).
