Peco Controls TA155-047 Thermostat

When you're dealing with 2-pipe or 4-pipe fan coil unit (FCU) systems, the Peco Controls TA155-047 provides the rugged, line-voltage reliability a veteran contractor expects. This electronic non-programmable thermostat is engineered with advanced self-configuring circuitry, allowing for direct installation across a wide input range from 24 to 277 VAC without the need for manual jumpers. Its solid-state design ensures high-precision temperature control (50-90°F) for both PTAC units and standard HVAC configurations, utilizing a traditional selector dial that eliminates the complexity of digital menus for the end-user.

The TA155-047 thermostat is specialized for manual changeover applications, featuring a dedicated Heat-Off-Cool switch and a 3-speed fan slide switch (High, Medium, Low). To maximize installation flexibility, this model includes both vertical and horizontal covers and utilizes a terminal block for secure wiring connections rather than loose leads. Whether you are performing a thermostat replacement or a new HVAC system installation, the triac-based outputs provide silent and dependable operation for pilot duty loads like valves and relays.

• Universal Voltage Compatibility: Supports 24V, 120V, 240V, and 277V AC for versatile field application.
• Contractor-Friendly Installation: Includes a terminal block and multi-directional mounting covers for a clean finish on any 2x4 junction box.
• Multi-Speed Fan Control: Integrated slide switch manages 3-speed fan motors for enhanced indoor airflow control.
• Solid-State Accuracy: Eliminates mechanical drift with electronic sensing, improving long-term performance in commercial environments.
• Remote Sensing Ready: Configurable for unit-mounted or remote thermistor sensing based on environmental requirements.

• Can this thermostat handle both 2-pipe and 4-pipe systems? Yes, the TA155 is designed to interface with various fan coil configurations, though 4-pipe systems may require specific wiring for manual switching.
• Does it support 277V lighting circuits? It is rated for 24-277 VAC, making it ideal for large commercial facilities with high-voltage HVAC infrastructure.
• How do I change the mounting orientation? The unit ships with two separate faceplates, allowing you to mount the hardware either vertically or horizontally to match existing wall footprints.
