Meet the TH115-A-240D-B Thermostat from Resideo Honeywell Home. This 7-day programmable, line-voltage thermostat delivers reliable control for baseboard heaters, radiant ceilings, convectors, or fan-forced heaters. Rated for 208/240V and up to 15 amps, it switches up to 3120 watts at 208V or 3600 watts at 240V using a robust SPDT relay.

Designed with a rectangular vertical white cover and compact dimensions (2.8 in W x 0.9 in D x 4.9 in H), it installs cleanly in standard wall boxes. The device uses a thermistor sensor for accurate temperature control and includes 6-inch tinned copper lead wires for easy wiring. It supports a broad ambient range from 32°F to 158°F and a user-setpoint of 40°F to 86°F, making it suitable for baseboard heaters, radiant ceilings, and other line-voltage heating applications.
