Electronic Line Voltage Thermostat · 3000 Watts Max at 240V · Non-Programmable · Ouellet OTH3000-A
What this product is for
The Ouellet OTH3000-A is a non-programmable electronic line voltage thermostat for electric resistance heating systems such as baseboard heaters and convectors. It is designed for 120/208/240V circuits and provides proportional pulsing control for steadier room temperature than basic mechanical thermostats.
Use for
- Electric baseboard heaters
- Wall convectors and similar electric heat
- Residential suites, offices, and light commercial rooms
- Retrofit replacements where a simple 2-wire line voltage thermostat is needed
Avoid for
- Low-voltage 24V heating controls
- 347V applications
- Loads above the thermostat's 12.5A maximum rating
- Applications requiring programmable scheduling or smart controls
Best for
Best for electricians and maintenance teams needing straightforward temperature control without programming. It is also a practical choice where wall space is limited and the connected electric heat load is within the thermostat's rating.
Installed in
Typically installed in homes, apartments, condos, offices, and similar heated spaces using electric baseboard or convector heat. Typical guidance for electric heat sizing is about 10 watts per sq ft in insulated spaces, so a 3000W load at 240V is commonly associated with approximately 250 to 300 sq ft of heating coverage. Actual performance depends on insulation, ceiling height, layout, exposure, and local electrical code.
Why this product exists
This thermostat exists for projects that need accurate electronic control and simple day-to-day operation. Non-programmable line voltage thermostats are commonly selected where occupants want manual setpoint adjustment without schedules, batteries, or network setup.
Compared with similar products
Compared with a mechanical thermostat, the OTH3000-A offers electronic control with proportional pulsing for more consistent comfort. Compared with programmable models, it is simpler to install and operate. Compared with higher-capacity Ouellet models, this version is intended for loads up to 3000W at 240V rather than larger heater banks.
