Johnson Controls TEC2126H-4 Control

The Johnson Controls TEC2126H-4 is a professional-grade N2 networked thermostat controller engineered for precision climate management in hospitality fan coil applications. As the direct replacement for TEC2126-H2, this unit facilitates seamless integration into existing Metasys Building Automation Systems (BAS) without requiring extensive hardware reconfiguration. Designed to handle two-pipe or four-pipe fan coil units, it supports on/off or floating control outputs, providing technicians with the flexibility needed for diverse mechanical setups. The integrated 3-speed fan control and PI time-proportioning algorithm eliminate traditional temperature offsets, ensuring a stable setpoint for guest comfort. With a clear backlit LCD display and a user-friendly interface, this 24 VAC hospitality thermostat allows for field calibration of over 20 configurable parameters. This controller is a critical component for maintaining high-efficiency HVAC networked control in commercial environments where reliable fan coil unit (FCU) operation is paramount.

• Universal Replacement: Serves as the direct replacement for TEC2126-H2, ensuring minimal downtime during field upgrades.
• Enhanced Network Connectivity: Built-in N2 Bus communication allows for remote monitoring and programming via a centralized Building Automation System.
• Precise Control Logic: Utilizes on/off or floating control outputs to accurately manage hot and chilled water valves.
• Optimized Guest Comfort: Features a 3-speed fan control and an intuitive backlit display for easy adjustments in low-light environments.
• Operational Efficiency: Includes two configurable binary inputs for advanced functions like door/window status or remote night setback.

Is the TEC2126H-4 compatible with non-networked systems?
While designed as an N2 networked device, it can operate as a stand-alone hospitality thermostat; however, its primary value lies in its BAS integration capabilities for site-wide monitoring.

Can this unit control 4-pipe fan coil systems?
Yes, the TEC2126H-4 is specifically designed for two-pipe or four-pipe fan coils and cabinet unit heaters utilizing on/off or floating signals.

What is the primary difference between this and the commercial TEC2126-4?
The hospitality model features a temperature scale selector key and specific defaults tailored for hotel guestrooms rather than standard office spaces.
