Resideo TH114-A-024T Thermostat
The Resideo TH114-A-024T is a specialized low voltage electric heat thermostat designed for 24 Vac systems, providing precise control for baseboard heaters, radiant ceiling panels, and convector fan-forced heaters. Engineered with a triac switching mechanism, this unit ensures silent operation, eliminating the clicking noises common in mechanical relays. It maintains a 0.9 degree accuracy with a 1 degree differential, utilizing a 15-minute cycle rate (4 cycles per hour) to prevent rapid cycling and ensure consistent thermal mass stability. The vertical mount interface features a clear backlit display for low-light visibility and an accessible on/standby switch for seasonal shutdowns. As a non-programmable 24V thermostat, it is ideal for contractors seeking a reliable, high-performance solution that integrates with existing relays or transformers in residential and commercial electric heating applications.
Key Benefits for Technicians:
- Silent Electronic Switching: Uses triac technology to deliver pulse-width modulation, improving comfort and component longevity.
- Precise Temperature Control: High-accuracy 0.9°F (0.5°C) sensing prevents temperature swings common in bimetal alternatives.
- Versatile Compatibility: Designed for 24V electric heating control, compatible with R841 and RC840 series electromechanical or solid-state relays.
- Rugged Reliability: Durable vertical construction with a 40-86°F setpoint range suited for standard HVAC environments.
Common Questions & Answers:
Can this thermostat be used for line voltage (120/240V) applications?
No, the TH114-A-024T is a 24 Vac model. It must be used with a 24V transformer or a companion relay such as the RC840-240 for 240V baseboard installations.
Is this model compatible with fan-forced heaters?
Yes, its 15-minute cycle rate and 4 cycles per hour configuration are optimized to protect fan motors while maintaining efficient heat distribution.
Does it require a C-wire (Common)?
This thermostat typically operates on a 2-wire R and C connection from the relay or transformer, ensuring stable power for the backlight and triac.
