Resideo TH140-28-01-B Programmable Thermostat
The Resideo TH140-28-01-B Programmable Thermostat is a versatile 7-day programmable digital thermostat designed for high-precision control in hydronic, line voltage, and low voltage heating environments. Engineered to handle everything from millivolt systems to 240 Vac heating applications, this unit is a staple for technicians installing electric baseboard heaters, as well as gas or oil-fired boilers. With a single pole double throw (SPDT) switching action, this thermostat provides reliable performance for 1-stage heat applications. It features an integrated pump protection function, which cycles the circulator pump for one minute every 24 hours to prevent seizure during long periods of inactivity—a critical failsafe for hot water heating systems. The remote input terminal allows for seamless integration with a telephone controller, enabling vacation mode overrides via external signals.
- Multi-Voltage Compatibility: Operates on 24 Vac, 120 Vac, and 240 Vac, supporting a wide range of residential and commercial heating equipment.
- Hydronic System Optimization: Built-in pump protection ensures hydronic circulators remain operational and free of sediment buildup.
- Precise Temperature Regulation: Maintains a tight ± 1 degree differential to prevent significant temperature swings and improve occupant comfort.
- Electronic Flexibility: Features a selectable Proportional Adaptive Mode to minimize cycle offsets and improve efficiency based on the specific heating system capacity.
Common Questions
Can the TH140-28-01-B control cooling systems?
This specific model is designed for 1-stage heating applications. While the SPDT relay provides flexibility, its primary programming and logic are optimized for heating, specifically for hydronic and line voltage electric heat.
Does this unit require a common wire (C-wire)?
For most standard applications, this is a battery-powered unit using two AA alkaline batteries, which allows for "armchair programming" by removing the faceplate. However, always refer to the specific wiring diagram for your system voltage to ensure proper terminal connections.
Is this thermostat compatible with 240V electric baseboards?
Yes, it is rated for line voltage applications. However, for loads exceeding the 5A resistive rating, an electromechanical relay must be used in conjunction with the thermostat.
