Choosing 120V or 240V
Choose 120V IfYour electric baseboard heater system is confirmed as 120V.
Choose 240V IfYour electric baseboard heater system is confirmed as 240V.
Ask an Electrician IfYou cannot safely confirm the system voltage, breaker type, wiring, or heater label.
How to Check Your Voltage
You may be able to identify voltage from your old thermostat label, heater label, breaker, or wiring.
Old thermostat labelHeater labelBreaker informationWiring photosVoltage tester readingLicensed electrician confirmation
As general clues, black and white wires may indicate a 120V system, black and red wires may indicate a 240V system, and a double-pole breaker often indicates a 240V heater circuit.
These are only general clues. Wire colors and breaker layouts can vary. Always confirm the actual system voltage before installation.
4-Wire Wiring Requirement
This thermostat is designed for 4-wire installations only. It is not suitable for simple 2-wire wall boxes.
If your existing thermostat box only has two wires, this model may not be compatible. Please check the wiring before ordering.
Load Selection Reminder
Before ordering, check your heater wattage. If multiple baseboard heaters are controlled by one thermostat, add their wattage together and confirm the total load does not exceed the thermostat rating.
120V Load LimitDo not exceed 2400W total connected heater load.
240V Load LimitDo not exceed 4800W total connected heater load.
Installation
Basic Installation Overview
This thermostat should be installed only after confirming voltage, load, and wiring compatibility.
Turn off power at the breaker.
Confirm the power is off using a proper voltage tester.
Remove the old thermostat cover.
Take clear photos of the existing wiring before disconnecting wires.
Confirm whether the system is 120V or 240V.
Confirm the wall box has a compatible 4-wire configuration.
Confirm the total heater load is within the thermostat rating.
Connect the thermostat according to the wiring diagram and product instructions.
Secure all wire connections properly.
Mount the thermostat to the wall box.
Restore power at the breaker.
Turn the dial to the desired temperature.
Confirm that the power and heat indicators work as expected.

When to Hire an Electrician
You are not sure whether your system is 120V or 240V
Your wall box has only two wires
You are not sure how to identify line and load wires
Your wiring colors do not match the instructions
Your heater load is close to the maximum rating
You need a true double-pole disconnect thermostat
Your local code requires professional installation
You are uncomfortable working with high-voltage wiring
Testing After Installation
After installation, turn the dial above room temperature. The heat indicator should turn on, and the electric baseboard heater should begin heating.
Then turn the dial lower. The heat indicator should turn off, and the heater should stop heating.
If the thermostat does not behave as expected, turn off power at the breaker and check the wiring or contact a qualified electrician.
How the Thermostat Works
Set the desired room temperature using the manual dial. When the room temperature drops below the set temperature, the thermostat activates the connected electric baseboard heater. When the room temperature rises back to the set level, the thermostat stops calling for heat.
Power IndicatorShows that the thermostat is receiving power.
Heat IndicatorShows that the thermostat is calling for heat and the heater should be operating.
Service and Maintenance Reminder
Do not rely on the thermostat OFF position when servicing the heater or thermostat.
Always turn off the circuit breaker before opening the thermostat, inspecting wiring, replacing the heater, or performing maintenance.
FAQ
Compatibility Questions
Is this thermostat only for electric baseboard heaters?
It is mainly designed for electric baseboard heaters and compatible line-voltage electric heating systems.
It should not be used as a general-purpose thermostat for unrelated YeloDeer heating products.
Does this thermostat work with 2-wire wiring?
No. This thermostat is designed for 4-wire wiring only.
If your wall box has only two wires, this model may not be compatible. Please check your wiring before ordering.
What does 4-wire only mean?
A 4-wire thermostat installation usually has separate line and load wires passing through the thermostat. This allows the thermostat to control the electric baseboard heater circuit properly.
If your existing wall box only has two wires, this thermostat may not match your wiring configuration. Please confirm before ordering.
Is this thermostat double-pole?
No. This thermostat is not a true double-pole DPST disconnect.
It controls the heating circuit, but it should not be used as a full electrical disconnect. If your installation requires a true double-pole disconnect thermostat, please choose a thermostat designed for that requirement.
Does the OFF position fully disconnect power?
No. The OFF position turns off the thermostat’s control function, but the main high-voltage power supply circuit may still remain live.
For safety, always turn off the breaker before installation, inspection, wiring, or service.
Voltage & Load Questions
How do I know whether I need 120V or 240V?
Check the old thermostat label, heater label, breaker, or wiring.
As general clues, black and white wires may indicate 120V, black and red wires may indicate 240V, and a double-pole breaker often indicates 240V.
However, wire colors are not always enough. Use a voltage tester or consult an electrician if you are unsure.
What happens if I choose the wrong voltage version?
Using the wrong voltage version can cause malfunction, unsafe operation, or damage.
Always confirm your heater system voltage before ordering and installation.
Can I control multiple baseboard heaters with one thermostat?
Possibly, only if the heaters are on the same compatible circuit and the total load does not exceed the thermostat rating.
Add the wattage of all connected heaters together. Do not exceed 2400W at 120V or 4800W at 240V.
If you are unsure, consult a licensed electrician.
Operation & Troubleshooting
What do the indicator lights mean?
The power indicator shows the thermostat is powered.
The heat indicator shows the thermostat is calling for heat and the baseboard heater should be operating.
Why is my heater not turning on?
Possible reasons include the breaker is off, wiring is incorrect, the wrong voltage version was selected, the heater load exceeds the rating, room temperature is already above the set temperature, wall box wiring is not compatible, the thermostat is not compatible with your heater, or the heater itself has an issue.
Turn off power at the breaker before inspecting wiring.
Why does the heater turn on and off around the set temperature?
This is normal thermostat operation. The thermostat turns the heater on when the room temperature drops below the set point and turns it off when the room temperature returns to the target level.
