Delivering Comfort and Efficiency

The T155 thermostat is designed for use with HVAC systems including two

or four-pipe fan coil applications. Available in both Auto Changeover and

Manual Changeover models, the T155 is ideal for installations requiring

either automatic internal switching between heating and cooling or manual

switching between heating and cooling. Solid state accuracy offers comfort

and efficiency, while contemporary styling complements room décor.

Universal Voltage Capability

Only PECO offers advanced self-configuring circuitry that allows the T155

electronic thermostat to be applied directly to input voltages from 24 to 277

VAC, 50 or 60Hz. Thermostat outputs are suitable for connection to relays,

valves and similar pilot duty loads. The system and fan switches will handle

inductive and resistive loads.

Configurable for Specific Applications

The standard T155 is user configurable for either unit or remote thermistor

sensing. Fan operation is continuous or can be cycled with the use of a load

handling relay.
