Product Details
The TA155 manual changeover thermostat is engineered for HVAC systems, specifically for two or four-pipe fan coil applications and other installations requiring manual switching between heating and cooling. It features solid-state accuracy for enhanced comfort and efficiency, complemented by a contemporary design that suits various room decors. The advanced self-configuring circuitry allows the thermostat to accept input voltages ranging from 24 to 277 VAC at either 50 or 60 Hz. Suitable for connection to relays, valves, and similar pilot duty loads, the thermostat can handle both inductive and resistive loads through its system and fan switches. It is available in standard models as either a heating/cooling thermostat or with integral switches for heat-off-cool and fan speed selection. User-configurable for unit or remote thermistor sensing, the TA155 can be set for continuous or cycled fan operation, given the appropriate load handling relay. Notable attributes include a direct switch from heat to cool with no dead-band, a rating of 10 VA at 24 VAC and 20 VA at 120-277 VAC, a temperature range of 50 to 90°F (10 to 32°C), solid-state precision and reliability, options for up to three-speed fan switching, and compliance with operational standards at both 50 and 60 Hz.
