Resideo TH115-AF-GA Thermostat
The Resideo TH115-AF-GA is a high-performance 7-day programmable line voltage thermostat designed specifically for electric heating applications, including high-wattage baseboard heaters, radiant ceilings, and fan-forced convectors. Engineered for professional installation, this 120/240 Vac programmable thermostat features a robust DPST switching action and supports a maximum load of 15 Amps (3600W at 240V). The integrated 5mA Class A GFCI provides essential ground fault protection, eliminating the need for a dedicated circuit breaker in many electric radiant floor heating configurations. Technicians can easily toggle between AF (Ambient + Floor) and F (Floor Only) modes, allowing for precise control over room air temperature while maintaining safe floor surface limits via the included 15-foot NTC thermistor floor sensor. The bright backlit display and vertical mounting profile ensure visibility in low-light mechanical areas, while the early start function and temporary bypass modes provide flexible operational control without disrupting complex programmed schedules.
Key Benefits- Dual-Voltage Versatility: Compatible with both 120V and 240V resistive loads, making it a standard stock item for various line voltage electric heating projects.
- Enhanced Safety: Built-in 5mA GFCI with a front-facing test light ensures local protection and simplified code compliance for wet-area 120/240V applications.
- Precise Comfort: Advanced temperature control minimizes fluctuations to 1 degree, maintaining consistent thermal mass in radiant floor heating systems.
- Contractor-Friendly Installation: Includes tinned copper lead wires and solderless connectors for fast, reliable terminations in standard vertical electrical boxes.
Can the Resideo TH115-AF-GA be used with a 2-wire setup?
This unit utilizes a 4-wire double pole (DPST) configuration, which is required for high-wattage line voltage applications to ensure a physical break on both power legs for increased safety.
What is the difference between AF and F mode?
AF mode monitors both ambient air and floor temperature (ideal for primary heating), whereas F mode exclusively monitors the floor sensor (perfect for floor warming applications in bathrooms or kitchens).
How do I reset the GFCI if the red test light is on?
To reset the ground fault protection, switch the thermostat to the "Off" position and then back to "On." If the light persists, check the load side for a ground fault or insulation damage.
