Important Before You Order
This is a high-power temperature controller, not a simple plug-in outlet thermostat.
It is more suitable for customers with wiring knowledge, installation experience, or professional support. Before purchasing, confirm that your equipment is 120V, within 30A / 3600W, and safe to control through an external thermostat.
Your device voltage is 120V Your device current draw does not exceed 30A Your device power does not exceed 3600W Your equipment can safely cycle on and off Your application uses heating mode or cooling mode correctly You can install the controller in a suitable panel or enclosure The controller body will be protected from water and physical damage You understand wiring or will use qualified installation support
Use It For / Do Not Use It For
Use It For Compatible 120V heating, cooling, fan, refrigeration, greenhouse, fermentation, incubation, and temperature-sensitive equipment within 30A / 3600W.
Do Not Use It For 240V equipment, devices above 30A / 3600W, medical or life-support systems, exposed outdoor mounting without enclosure, or equipment that cannot safely cycle on and off.
Heating Mode vs Cooling Mode
Heating Mode Use when the controller should turn equipment on when the measured temperature is too low. Typical uses include heaters, heating cables, heat mats, incubators, fermentation warming, greenhouse heating, and terrarium heating.
Cooling Mode Use when the controller should turn equipment on when the measured temperature is too high. Typical uses include ventilation fans, exhaust fans, refrigerators, cooling equipment, greenhouse ventilation, and brewing cooling systems.
For compressor-based cooling equipment, use the compressor delay function to reduce rapid cycling. Set the delay according to the equipment’s requirements and application conditions.

How Heating Mode Works
In heating mode, the controller turns the connected heating device on when the measured temperature is below your set point.
When the temperature rises to the target range, the controller turns the heating device off according to the control settings.
How Cooling Mode Works
In cooling mode, the controller turns the connected cooling device on when the measured temperature is above your set point.
When the temperature drops to the target range, the controller turns the cooling device off according to the control settings.
0.1°F Precision Control
The controller supports 0.1°F fine adjustment, which is useful for temperature-sensitive applications.
Incubation Fermentation Brewing Reptile Care Seedling Control Greenhouse Control Storage Management Temperature Testing
For best performance, place the probe where it reflects the actual temperature you want to control.
30A / 3600W Load Capacity
This controller is designed for higher-power applications than standard plug-in thermostat outlets.
Voltage Amperage Wattage Startup current if applicable External thermostat control suitability Circuit and wiring capacity
Do not exceed 30A / 3600W. If your device has a motor or compressor, check startup current and manufacturer requirements before using an external temperature controller.
Compressor Delay Protection
What It Does Helps reduce rapid compressor cycling by delaying restart after shutoff.
Useful For Refrigerators, cooling units, compressor-based equipment, and temperature-controlled storage.
Delay Range Adjustable from 0 to 31 minutes depending on equipment needs.

Important Installation Notes
Not Plug-In Ready This controller is not a simple plug-in outlet thermostat. Wiring and mounting may be required.
120V Only Install only within the rated 120V, 30A / 3600W limit.
Use Proper Enclosure Install in a suitable panel, box, or enclosure and protect the controller body from water and impact.
Check Equipment Cycling Do not use with devices that cannot safely cycle on and off.
Use Compressor Delay Use delay protection for compressor-based cooling equipment.
Use Qualified Support If you are not familiar with wiring, consult a qualified electrician or technician.
Sensor Probe Placement
Correct probe placement is critical for accurate control.
Good Probe Placement Place the probe where you want the temperature measured. Secure it so it does not move during operation.
Avoid These Issues Avoid direct heater output, unstable fan airflow, direct sunlight, or locations that do not represent the target temperature area.
The included probe is IP68 waterproof, but the controller body and electrical connections must still be protected from water, condensation, and standing water.
Using High / Low Temperature Alarms
Fermentation Helps alert you when process temperature moves outside your target range.
Incubation Useful for monitoring temperature-sensitive hatching or incubation conditions.
Greenhouses Helps monitor heating or ventilation systems in changing outdoor conditions.
Refrigeration Useful for cold storage and cooling equipment monitoring.
Animal Enclosures Helpful for terrariums, reptile care, and controlled habitats.
Storage Areas Supports temperature-sensitive storage control and monitoring.
Using the Keypad Lock
The keypad lock helps protect your settings from accidental changes.
