Peco Controls T8168-1 Thermostat

The Peco Controls T8168-1 Thermostat is a high-performance proportional digital thermostat engineered for demanding commercial and industrial HVAC applications, including fan coil units (FCU) and PTAC systems. As the direct replacement for TB158-100, TB158-003, TB158-017, TA158-100, and TA168-100, this unit handles 2-pipe and 4-pipe configurations with ease. It features 3-speed fan control (High, Medium, Low) and supports 0-10 VDC, 4-20 mA, or three-wire floating valve outputs. Technicians can configure the T8168-1 for programmable or non-programmable operation, utilizing a 365-day calendar with up to four events per day. With its 24 VAC supply voltage and 10 VA output ratings, it provides reliable switching for relays, dampers, and valves. Advanced logic supports remote temperature sensing, occupancy-based fan selection, and deadband auto-changeover to maintain precise climate control within a 1.0°F differential.

• Universal Compatibility: Serves as a versatile HVAC replacement part for legacy PECO TA and TB series controllers.
• Multi-Output Flexibility: Supports 0-10V modulating control for valves and fans, alongside standard 24 VAC ON-OFF switching.
• Enhanced System Logic: Includes seasonal summer-winter changeover and keypad lockout with PIN for secure facility management.
• Energy Conservation: Integrated setback scheduling and door-open shutdown sensors minimize unnecessary equipment cycling.
• High-Resolution Display: A large, backlit digital screen displays local or averaged temperature sensing data for accurate diagnostics.

Is the T8168-1 compatible with BACnet systems?
Standard T8168-1 models are standalone; however, specialized BACnet and Wi-Fi variants are available within the series for broader building automation integration.

Can this thermostat control a 0-10V fan?
Yes, the T8168-1 is designed to manage 0-10 VDC fan outputs or up to three discrete 24 VAC fan speeds through its configurable service menu.

Does this unit replace the TB158-100 directly?
Yes, it is the primary manufacturer-designated upgrade for legacy TB158 and TA158 series controllers used in fan coil applications.
