Programmable Thermostat

The Resideo TH115-A-240D-B/U is a 240 VAC, 15A line-voltage programmable thermostat engineered for electric baseboard and in-wall heating systems operating at 208-240 volts. This industrial-grade controller delivers precise temperature management with a temperature variation of just 0.5 Degrees C (1.0 Degrees F), making it ideal for applications requiring consistent comfort and energy efficiency. The unit supports a maximum load capacity of 3600 watts at 240 volts with resistive loads, utilizing a double pole, 4-wire connection for safe and reliable installation. Featuring microprocessor-based proportional adaptive regulation with 15-minute optimization cycles, this thermostat continuously learns from system performance to maximize heating efficiency. The large backlit LCD display provides clear visibility in any lighting condition, while the compact vertical-mount design (70 x 124 x 23 mm) fits standard wall openings without requiring extensive modification. Built for commercial and residential applications, this replacement thermostat offers flexible 7-day independent programming capabilities to accommodate varying occupancy schedules and seasonal demands. The proportional control system reduces energy consumption while maintaining optimal temperature accuracy, making it an economical choice for facility managers seeking to upgrade older control systems. This unit is compatible with existing Resideo TH115-A-240D installations and serves as a reliable replacement for equivalent line-voltage thermostat applications. Its robust construction and proven Resideo engineering ensure dependable operation in demanding HVAC environments.
