Peco Controls T4522-001 T-Stat

The Peco Controls T4522-001 is a robust 2H/2C programmable thermostat engineered for precise climate control in commercial and residential HVACR applications. Operating on 24VAC, this digital low voltage thermostat supports up to two-stage heating and two-stage cooling configurations, making it compatible with both conventional systems and heat pump systems with auxiliary heat. The unit features non-volatile memory to prevent program loss during power failures and offers 7-day programming flexibility with four periods per day. Its large backlit display provides clear visibility of the setpoint and ambient temperature, while the intuitive interface allows for seamless HVAC system integration and field calibration. Designed for durability and accuracy, the T4522-001 ensures optimal compressor protection via adjustable short-cycle timers, facilitating reliable performance for contractors managing complex multi-stage equipment.

• Multi-Stage Compatibility: Supports 2 stage heat 2 stage cool setups for high-efficiency system management.
• Dual Powered: Runs on 24VAC hardwire or battery backup for continuous programmable climate control.
• System Protection: Integrated short-cycle protection prevents frequent compressor cycling to extend component lifespan.
• Flexible Scheduling: 5/2 or 7-day programming profiles accommodate varied occupancy schedules in commercial spaces.
• User Interface: Large, high-contrast display ensures easy navigation for field technicians and end-users.

Is the T4522-001 compatible with millivolt systems?
No, this model is designed for 24VAC systems and is not compatible with millivolt or line voltage (120/240V) applications.

Can this thermostat manage a heat pump with auxiliary heat?
Yes, the Peco T4522-001 is specifically designed to handle multi-stage heat pump configurations including emergency heat cycles.

Does this unit require a common wire (C-wire)?
While it can be battery-powered, a C-wire is highly recommended for continuous backlight operation and to ensure uninterrupted power to the logic board.
