Product Details
The TA155 manual changeover thermostat is designed for use in HVAC systems, including two-pipe fan coil applications or other installations requiring manual switching between heating and cooling. It features solid state accuracy for enhanced comfort and efficiency, complemented by contemporary styling that fits with room decor. The advanced self-configuring circuitry allows the thermostat to operate directly on input voltages ranging from 24 to 277 VAC at 50 or 60 Hz. Its outputs can connect to relays, valves, and similar pilot duty loads, while the system and fan switches can handle both inductive and resistive loads. Standard models are available as a heating/cooling thermostat only or with integral switches for heat-off-cool and fan speed selection. The T155 is user configurable for either unit or remote thermistor sensing and supports fan operation for either continuous or cycled operation with a load handling relay. Key features include 1 heat/1 cool on-off system switch, Hi-Med-Lo fan switch, a temperature range of 50 to 90°F (10 to 32°C), solid state precision and dependability, up to three speed fan switching, and operation at 50 or 60 Hz. Warranty information applies.
