Johnson Controls TEC3322-14-000 Thermostat

The Johnson Controls TEC3322-14-000 is an advanced 0-10 VDC proportional thermostat designed for precise fan coil unit control and zoned HVAC systems. Engineered as the direct T605DFH-4 replacement, this low voltage networked thermostat features a backlit LCD interface and supports BACnet MS/TP communication for seamless building automation integration. As a high-performance proportional controller, it manages analog heating and cooling signals to maintain tight temperature tolerances in commercial environments. This model is optimized for modulating valve control and multi-speed fans, providing technicians with a reliable solution for upgrading legacy pneumatic to electronic conversions. Its onboard occupancy sensor compatibility and configurable staging ensure maximum energy efficiency without compromising occupant comfort. For contractors, the menu-driven configuration simplifies the thermostat commissioning process, allowing for rapid deployment in large-scale mechanical projects while maintaining compatibility with existing commercial HVAC controls infrastructure.

• Universal Replacement: Specifically designed as the drop-in upgrade for the T605DFH-4, ensuring electrical and physical compatibility.
• Precision Signal Output: Provides a 0-10 VDC analog control signal for accurate modulation of chilled water or hot water valves.
• Field-Configurable: Features an intuitive setup menu for adjusting deadband settings, setpoint limits, and fan speed sequences.
• Enhanced Connectivity: Integrates easily into Metasys or other open-protocol BMS systems for centralized monitoring and scheduling.
• Contractor-Friendly Design: Utilizes a removable screw terminal block to streamline wiring and reduce installation time in the field.

How do I wire the 0-10 VDC output for modulating valves?
The TEC3322-14-000 utilizes dedicated AO1 and AO2 terminals for cooling and heating signals; ensure the common wire is landed on the COM terminal to maintain signal integrity.

Can this unit control multi-speed fans?
Yes, this proportioning thermostat is configurable to manage 1-speed, 2-speed, or 3-speed fans through its digital output relays based on the internal logic settings.

Is this model compatible with external sensors?
This controller supports remote temperature sensors and discrete inputs for pipe sensors or occupancy overrides, allowing for flexible mounting in diverse mechanical layouts.
