Resideo TH115-A-240S-B Thermostat
The Resideo TH115-A-240S-B is a contractor-grade 7-day programmable line voltage thermostat engineered specifically for high-capacity 240 Vac electric heating systems. Designed for precise thermal management, this unit handles resistive loads up to 16.7 Amps (4000W @ 240V), making it the standard choice for baseboard heaters, radiant ceilings, convectors, and fan-forced heaters. The integration of an epoxy-soundproofed relay ensures silent switching, eliminating the mechanical clicking typically associated with line-voltage controls. With a 1-degree differential and triac-based precision, this thermostat minimizes temperature swings to maintain consistent comfort in demanding residential or light commercial environments.
Key Benefits- High-Capacity Performance: Rated for up to 4000 Watts at 240V, providing robust control for heavy-duty electric resistance heating.
- Advanced Programming: Features 7-day programmability with four daily settings and an Early Start function to ensure reached setpoints by the scheduled time.
- Inductive Load Compatibility: Unlike many electronic thermostats, this model is verified for use with fan-forced heaters.
- Non-Volatile Memory: The battery-free backup preserves your custom schedules indefinitely through power interruptions.
- Operational Quietness: The epoxy-encapsulated relay provides near-silent operation, essential for bedroom and living area installations.
Does this thermostat require a neutral wire?
This is a 4-wire single-pole (SPST) installation. It requires two power leads from the source and two leads to the heater load to power its digital display and logic.
Is the display backlit for low-light visibility?
Yes, the vertical mount interface includes a backlit LCD that activates upon button press for clear reading of ambient and setpoint temperatures.
Can I use this for 120V or 208V applications?
While optimized for 240 Vac, it is rated for 208 Vac (3475W). Verify your total wattage load against the 16.7A limit before field installation.
