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.
This mode is suitable for heaters, heating mats, heating cables, incubators, fermentation warming, and greenhouse heating.
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.
This mode is suitable for fans, ventilators, refrigerators, cooling equipment, and greenhouse ventilation.
0.1°F Precision Control
The controller supports 0.1°F fine adjustment, which is useful for temperature-sensitive applications such as:
• Incubation
• Fermentation
• Brewing
• Reptile care
• Seedling and greenhouse control
• Storage temperature management
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.
Before connecting equipment, check the device label and confirm:
• Voltage
• Amperage
• Wattage
• Startup current if applicable
• Whether the device is suitable for thermostat-controlled cycling
Do not exceed 30A / 3600W.
Compressor Delay Protection
For compressor-based cooling equipment, the adjustable 0–31 minute compressor delay helps reduce rapid cycling.
This can help protect:
• Refrigerators
• Cooling units
• Compressor-based equipment
• Temperature-controlled storage systems
Set the delay according to the equipment’s requirements and application conditions.

FAQ & Resources
Additional Product Questions
1. Is this controller for heating or cooling?
This controller supports both heating and cooling modes.
Use heating mode when you want the connected device to turn on when temperature is too low.
Use cooling mode when you want the connected device to turn on when temperature is too high.
2. How is this different from YeloDeer plug-in thermostats?
This model has a much higher load capacity: 30A / 3600W.
It is designed for higher-power and more professional applications.
YeloDeer plug-in thermostats are easier to use and suitable for lower-power heating or fan applications, but they do not provide the same 30A high-power capacity.
3. Is it plug-and-play?
No. This is a panel-mount high-power temperature controller. It is not a simple plug-in outlet thermostat. Installation may require wiring, mounting, and electrical knowledge.
If you want a plug-in product, choose YeloDeer Digital Plug-In Thermostat or Digital Cooling Thermostat Outlet.
4. Can I use this with a heater?
Yes, if the heater is 120V and does not exceed 30A / 3600W.
Make sure the heater can safely be controlled by an external thermostat.
5. Can I use this with a refrigerator or cooling unit?
Yes, it may be used with compatible compressor-based cooling equipment within the rated load. Use the compressor delay function to reduce short cycling and help protect the compressor.
6. Can I use this with an air conditioner?
Only if the air conditioner is compatible with external thermostat control, uses 120V, and does not exceed 30A / 3600W. For compressor equipment, compressor delay protection should be used. If you are unsure, check the AC unit specifications or consult a qualified technician.
7. Can I use this with a fan?
Yes. It can control compatible ventilation fans, exhaust fans, and cooling fans within rated load. For smaller plug-in fan applications, YeloDeer Digital Cooling Thermostat Outlet may be easier to use.
8. Can I use this with pipe heat tape or heating cable?
Yes, if the heating cable or pipe heating system is within the rated load and is suitable for thermostat-controlled operation. For small plug-in pipe heat tape systems, YeloDeer Digital Plug-In Thermostat may be easier.
9. Can the probe be used in wet or humid environments?
The included sensor probe is IP68 waterproof and suitable for humid or wet sensing environments. However, the controller body and electrical connections must still be protected from water and moisture.
Do not expose the controller body to direct water, condensation, or standing water.
10. What does 0.1°F precision mean?
It means the controller supports fine temperature adjustment in 0.1°F increments.
This is helpful for applications where small temperature changes matter, such as fermentation, incubation, brewing, and temperature-sensitive storage.
11. What is compressor delay protection?
Compressor delay prevents the compressor from restarting too quickly after shutting off.
This helps reduce rapid cycling, which can cause wear or damage to refrigerators, cooling units, and compressor-based equipment.
12. Can I lock the settings?
Yes. The keypad lock helps prevent accidental changes to your temperature settings, which is useful for shared spaces, workshops, greenhouses, and long-term control setups.
13. What should I send if I need help confirming compatibility?
