Resideo TH115-AF-024T Thermostat
The Resideo TH115-AF-024T is a specialized 24 Vac electric heat thermostat engineered specifically for hydronic or electric radiant floor heating systems. Designed for precision control, this 7-day programmable thermostat operates within a 32-120 degree Fahrenheit range with a tight 1 degree differential to prevent temperature overshoot. This model features AF sensing logic, allowing for simultaneous monitoring of ambient air temperature and floor temperature via a remote sensor to ensure both comfort and floor material protection. The unit requires an external electromechanical relay for high-voltage switching, making it an ideal choice for contractors looking for low-voltage control over high-current heating loads. Its vertical mount design and clean white finish provide a professional appearance while the digital floor heating control interface allows for granular scheduling. This unit is essential for maintaining consistent thermal mass performance in residential or commercial slab heating applications where 0.5 HP 24V thermostat reliability is required.
- Precision Sensing: Utilizes an floor sensor input to maintain exact floor temperatures while monitoring ambient air.
- Contractor Grade Reliability: Designed to interface with 24V relays for robust switching of radiant heating cables or mats.
- Programmable Efficiency: 7-day scheduling allows for setback periods, reducing energy consumption in high-draw electric heat systems.
- Tight Differential: The 1-degree temperature swing ensures the heating system reacts quickly to load changes.
Common Questions
Can this thermostat be used without a floor sensor?
While the TH115-AF-024T is optimized for dual sensing, it can be configured to monitor ambient air only, though floor sensing is recommended for radiant applications to prevent floor damage.
What type of relay is required for operation?
This is a low-voltage (24 Vac) controller and must be paired with an external electromechanical relay or a transformer-relay (like the RC840T) to switch 120V or 240V heating loads.
Does this unit support cooling modes?
No, this model is strictly a heating-only thermostat designed specifically for radiant heat and electric baseboard integration.
