TrolMaster Digital Day/Night Temperature Controller (BETA-4)
The TrolMaster Digital Day/Night Temperature Controller (BETA-4) is a standalone environmental controller that automatically operates compatible heating or cooling equipment based on the temperature of your grow room, grow tent, greenhouse, or other controlled environment. With separate day and night temperature settings, a built-in photocell, a digital display, and a remote temperature sensor, the BETA-4 provides simple temperature automation without a larger environmental control system.
You can plug compatible heating or cooling equipment directly into the controlled outlet on the bottom of the BETA-4. The controller then switches the connected device ON or OFF automatically according to the programmed temperature settings.
Automatic Heating or Cooling Control
The BETA-4 can be configured to control either heating or cooling equipment.
Depending on the application, it can be used with compatible equipment such as:
- Heaters
- Cooling equipment
- Exhaust or ventilation devices
- Other temperature-control equipment within the electrical rating
The BETA-4 monitors the temperature through its remote sensor and automatically switches the connected equipment according to the selected temperature setpoint.
Separate Day and Night Temperature Settings
A built-in photocell automatically detects whether the growing environment is in a light or dark period.
Separate temperature setpoints can be programmed for:
This allows growers to maintain different temperature targets during lights-on and lights-off periods without manually adjusting the controller.
Built-In Day/Night Photocell
The integrated photocell automatically detects changes between day and night conditions.
When the lighting cycle changes, the BETA-4 switches to the corresponding temperature setting. This makes it especially useful for indoor gardens where the desired nighttime temperature differs from the daytime target.
The photocell detects the presence or absence of light rather than measuring light intensity.
Remote Temperature Sensor
The BETA-4 includes a remote temperature sensor, allowing you to place the sensing point away from the controller.
Placing the sensor closer to the plant canopy can provide a more representative measurement of the temperature experienced by the crop.
This also lets you install the controller in a convenient, accessible location while keeping the sensor in the preferred monitoring area.
5°F Temperature Deadband
The BETA-4 uses a 5°F temperature deadband to help prevent connected heating or cooling equipment from rapidly switching ON and OFF around the selected temperature setpoint.
This operating range helps provide stable temperature control while reducing unnecessary cycling of connected equipment.
Digital Display and Simple Controls
The BETA-4 features a clear digital display and a simple three-button interface.
This allows users to quickly program and review temperature settings without complicated menus or additional equipment.
Once configured, the controller automatically manages the connected heating or cooling device according to the current temperature and day/night status.
Controls Equipment up to 10A
The BETA-4 is designed to control compatible heating or cooling devices drawing 10A or less.
The controller operates from a 120 VAC power supply and uses an internal relay to switch the connected equipment.
Always verify the equipment's voltage and current requirements before connecting it to the controller.
Standalone Temperature Control
The BETA-4 operates independently and does not require a Hydro-X or another central TrolMaster controller.
Simply connect the temperature sensor, plug the BETA-4 into a compatible 120V outlet, program the desired day and night temperatures, and connect the heating or cooling equipment.

Compatible With
The TrolMaster BETA-4 is designed for compatible 120V heating and cooling equipment drawing 10A or less, including:
- Electric heaters
- Cooling devices
- Compatible exhaust and ventilation equipment
- Other thermostatically controlled devices within the electrical rating
Because the BETA-4 operates as a standalone temperature controller, it does not require a separate TrolMaster environmental control platform.
Simple Day and Night Temperature Automation
Maintaining consistent temperatures can require frequent manual adjustments when daytime and nighttime conditions change. The TrolMaster BETA-4 simplifies this process by automatically switching between separate day and night temperature settings and controlling connected heating or cooling equipment as needed.
For growers looking for a straightforward standalone solution for temperature automation, the TrolMaster Digital Day/Night Temperature Controller (BETA-4) provides simple, reliable control for compatible heating or cooling equipment up to 10A.
