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.
