Resideo TH114-A-120S Thermostat
The Resideo TH114-A-120S is a high-performance non-programmable line voltage thermostat engineered for precise control of 120V electric heating systems. Designed for heavy-duty applications, this unit features SPST switching and a 15-amp resistive load capacity, making it an ideal solution for baseboard heaters, convector units, and fan-forced heaters. Utilizing advanced TRIAC switching technology, the TH114-A-120S eliminates the clicking noise associated with traditional relays while providing 0.9-degree temperature accuracy. With 4 cycles per hour and a temperature setpoint range of 40°F to 86°F, this double-pole thermostat alternative ensures consistent thermal comfort and prevents the wide temperature swings typical of mechanical controls. The backlit digital display provides clear visibility in low-light environments, while the dedicated On/Standby switch allows for a positive system shut-off during seasonal transitions.
Key Benefits
- Precision Temperature Control: Maintains a 0.9-degree differential to ensure consistent comfort levels and improved energy efficiency in radiant ceiling and electric heat applications.
- Silent Operation: The solid-state TRIAC switching mechanism provides 100% silent operation, perfect for bedrooms and quiet commercial spaces.
- High Load Capacity: Rated for up to 3600W at 120 Vac, allowing for direct control of high-wattage electric baseboard heaters.
- Enhanced Visibility: Feature-rich white vertical mount interface includes a large backlight for ease of use in dark hallways or mechanical rooms.
Common Questions
Can this thermostat be used with 240V systems?
No, the TH114-A-120S is specifically calibrated for 120 Vac installations. For 240V applications, a compatible 240V model must be utilized to prevent component failure.
Is this unit compatible with fan-forced heaters?
Yes, it is designed to manage 15-minute cycles, which is the standard technical requirement for fan-forced heaters and convectors.
Does it require a neutral wire?
As a line voltage electric heat thermostat, it requires direct connection to the power leads; always verify your local electrical code and wiring configuration before installation.
