Resideo TH115-AF-120S Thermostat
For contractors and HVAC professionals, the Resideo TH115-AF-120S Thermostat is the industry standard for managing high-capacity electric heating systems. Engineered with a dedicated epoxy soundproofed relay, this unit eliminates the invasive clicking noise typical of mechanical line-voltage controls, making it ideal for high-end residential and commercial floor heating or electric baseboard heater retrofits. This 120 Vac vertical-mount controller supports up to 2000 Watts at 16.7 Amps, providing a robust interface for radiant ceiling panels, convectors, or fan-forced heaters. The integrated 7-day programmable schedule allows for four daily independent settings, ensuring maximum energy efficiency while maintaining a 1-degree differential temperature for precise thermal stability.
The TH115-AF-120S features a sophisticated AF/A/F mode selection, which allows for ambient air monitoring with floor temperature limitation, or dedicated floor sensing using the included thermistor. Built with a vertical mount profile, it fits standard electrical boxes and utilizes SPST switching action for reliable long-term performance in demanding electric heating applications. Its large backlit LCD offers clear visibility for homeowners, while the technicians benefit from its simple 4-wire installation and non-volatile memory that retains user programming through power interruptions.
Key Benefits for Field Application- Versatile Control Modes: Seamlessly switch between Ambient (A), Floor (F), and Ambient with Floor Limit (AF) modes for custom radiant installations.
- Silent Operation: The epoxy-soundproofed relay provides near-silent switching, essential for bedroom and office environments.
- High Amperage Capacity: Rated for up to 16.7A (2000W @ 120V), compatible with most high-output radiant floor heating and electric heat systems.
- Early Start Feature: On-board logic calculates the lead time required to reach the set temperature by the scheduled time.
- Vertical Form Factor: Specifically designed for vertical electrical boxes, maintaining a clean, professional aesthetic on the wall.
Is the floor sensor included with the TH115-AF-120S?
Yes, the unit comes standard with a 15-foot floor sensor (thermistor) to facilitate AF and F mode operation right out of the box.
Can this thermostat be used for 240V heating applications?
No, the TH115-AF-120S is specifically rated for 120 Vac. For 240V systems, use the TH115-AF-240S model to ensure voltage compatibility and safety.
What type of loads are compatible with the SPST switching action?
This thermostat is designed for resistive loads only, such as electric baseboards and radiant systems. It is not intended for inductive loads or cooling equipment.
