Peco Controls TA155-018 Tstat

When you are specified for a fan coil unit (FCU) retrofit or new construction, the Peco Controls TA155-018 provides a rugged, field-proven solution. This 24-277V thermostat features advanced self-configuring circuitry, allowing it to handle both low-voltage and line voltage HVAC applications without complex jumper settings. Designed for high-reliability 2-pipe and 4-pipe fan coil systems, this SPDT thermostat delivers solid-state accuracy to manage valves and resistive loads with precision. Its manual changeover interface allows contractors to maintain direct control over seasonal heating and cooling transitions. The universal voltage capability makes it a versatile stock item for service trucks, capable of replacing a wide range of non-programmable thermostats in commercial environments, including PTACs and air ventilators. With its vertical orientation and terminal block connections, it secures quickly to a standard 2x4 device box, ensuring a clean, professional finish that complements modern room aesthetics while providing the durability required for pilot duty loads.

• Universal Compatibility: Self-configuring for any input voltage from 24 VAC to 277 VAC, simplifying inventory for HVAC contractors.
• Precise Load Control: Handles inductive and resistive loads for valves and relays, specifically optimized for fan coil unit applications.
• Flexible Sensing: User-configurable for either local sensing or remote thermistor integration to meet specific commercial HVAC zoning requirements.
• Robust Switching: Features a single-pole double-throw (SPDT) configuration for reliable control of heating and cooling cycles.

Can this thermostat control multi-speed fans?
The TA155-018 is the base model without integrated fan switches. For multi-speed switching, external relays are required, or a model with built-in 3-speed switches should be selected.

Does it require a neutral wire for 277V installations?
Yes, proper wiring for line voltage requires following the TA155 wiring diagram to ensure the unit is powered correctly across its universal range.

Can this replace an older mechanical fan coil thermostat?
Absolutely. Its electronic design provides superior accuracy over older bimetallic models and fits standard mounting footprints.
