Programmable Thermostat

The Resideo TH115-A-240S-B is a 7-day programmable line-voltage thermostat engineered for precise temperature control in electric heating applications. This industrial-grade unit is compatible with baseboards, radiant ceiling systems, convectors, and fan-forced heaters, making it ideal for residential and light commercial installations requiring reliable thermal management. Rated for 240 VAC at up to 4000 W (16.7 A resistive load) and 208 VAC at up to 3475 W, this thermostat delivers robust performance across standard electrical configurations. The advanced temperature control system minimizes temperature swings to maintain consistent comfort levels while optimizing energy efficiency. Key operational features include an ON/STANDBY switch for seasonal shutdown and security, real-time heating power indicator for monitoring consumption, and Early Start functionality that preheats systems to reach programmed temperatures on schedule. The temporary bypass function allows quick override of settings without disrupting programmed schedules, providing operational flexibility when needed. This thermostat maintains programming integrity through battery-free backup technology, ensuring settings are retained during power interruptions. The combination of programmable scheduling, intuitive controls, and dependable performance makes this unit a practical replacement solution for existing Resideo and Honeywell installations requiring upgrade or repair. Engineered to meet industrial supply standards, the TH115-A-240S-B offers straightforward installation and operation for facilities managers and HVAC professionals managing electric heating systems.
