Description
The TA155 auto changeover thermostat is designed for use in HVAC systems including two or four-pipe fan coil applications or other installations requiring manual switching between heating and cooling. Solid state accuracy offers comfort and efficiency while contemporary styling complements room decor. Advanced self-configuring circuitry allows the T155 electronic thermostat to be applied directly to input voltages from 24 to 277 VAC , 50 or 60Hz. T h e r m o s t at outputs are suitable for connection to relays, valves and similar pilot duty loads. The system and fan switches will handle 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 standard T155 is user configurable for either unit or remote thermistor sensing. Fan operation, which is dependent on external connections, can be used for either continuous operation or cycled operation with the use of a load handling relay.
