Resideo TH114-A-240S-B Thermostat
The Resideo TH114-A-240S-B is a contractor-grade non-programmable electronic thermostat engineered for high-voltage 208/240 Vac applications. Designed for precise electric heating control, this unit features SPST switching and is rated for a maximum load of 3600W at 240V, making it ideal for baseboard heaters, radiant ceilings, and convector systems. Unlike mechanical line-voltage thermostats that suffer from wide temperature swings, this model maintains a tight 0.9 degree accuracy with 4 cycles per hour to ensure consistent comfort and bridge the gap between efficiency and performance. The vertical mount housing includes a clear backlit display for low-light visibility and an integrated on/standby switch for seasonal shutdowns. For technicians installing fan-forced heaters or electric resistance heat, the TH114-A-240S-B provides a reliable, silent electronic switching solution that eliminates the clicking associated with traditional relays while maintaining a 40-86 degree setpoint range.
- Enhanced Thermal Stability: Tight 1-degree differential prevents rapid cycling in line voltage electric heat systems.
- Versatile Application: Compatible with radiant ceiling panels and fan-forced heating through robust electronic TRIAC switching.
- User-Centric Design: Includes a backlight for easy adjustments in dark hallways and a dedicated power switch for maintenance.
- Simplified Installation: Standard two-wire non-polarized connection streamlines the replacement of older mechanical thermostats.
Common Questions
Can I use the TH114-A-240S-B for a 120V heater?
No, this specific model is designed for 208/240 Vac systems. Using this on a 120V circuit may result in failure or unsafe operation; always verify your supply voltage at the junction box before installation.
Does this thermostat work with inductive loads like fan-forced heaters?
Yes, the TH114-A-240S-B is rated for both resistive and inductive loads, making it suitable for convector units and fan-forced wall heaters within its amperage rating.
Why is my display blank?
Ensure the on/standby switch is set to "On." If the display remains blank, check the circuit breaker, as this unit is powered directly by the 240V line voltage.
