Programmable Thermostat

This 240 VAC, 15-amp line-voltage digital thermostat serves as a direct replacement for the Resideo TH115-A-240D-B/U and compatible models. Engineered for precise temperature control of electric baseboard heaters, wall-mounted heaters, and high-capacity resistive heating systems up to 3600 watts, this unit delivers reliable performance in residential and light commercial applications. The thermostat accommodates both 240 VAC and 208 VAC installations, providing flexibility across diverse electrical configurations. The device features a 7-day programmable schedule, allowing users to establish customized heating patterns for maximum energy efficiency and occupant comfort. Its proportional adaptive control system, optimized by internal microprocessor technology, operates on 15-minute heating cycles with zero crossover switching to minimize electrical stress and extend component life. The temperature control maintains +/-1 Degrees F accuracy with a comfortable 1 Degrees F differential, while setpoint range spans 40 to 85 Degrees F, suitable for most climate control requirements. Compact dimensions of approximately 4.9 by 2.8 by 0.9 inches enable straightforward installation in standard wall-mounted applications. The unit's robust construction ensures durability in demanding heating environments. Whether upgrading aging thermostats or specifying equipment for new heating system installations, this replacement delivers the dependable temperature management and energy-saving features required for cost-effective operation. Ideal for facility managers, HVAC contractors, and building maintenance professionals seeking quality replacements for legacy Resideo heating controls.
