Programmable Thermostat

This replacement thermostat is engineered to match the performance specifications of the Resideo TH115-A-120S, providing reliable temperature control for 120 VAC line-voltage electric heating systems. Designed for residential and light commercial applications, this digital thermostat is compatible with baseboard heaters, radiant ceiling systems, convectors, and fan-forced heating units, making it a versatile choice for zone heating installations. The unit features a 7-day programmable schedule that allows independent settings for each day of the week, maximizing energy efficiency and occupant comfort. The large backlit LCD display ensures easy readability in various lighting conditions, while the digital interface provides precise setpoint control within the 40 to 86 degrees Fahrenheit range. With a rated capacity of 16.7 amperes at 120 VAC resistive load (up to 2000 watts), this thermostat handles most standard electric heating applications with a minimum load requirement of 250 watts. Built for straightforward installation, the thermostat features a compact vertical-mount design with single-pole switching capability and 4-wire connection configuration, simplifying retrofit or new construction projects.
