Johnson Controls TEC3612-14-000 Thermostat Controller is a white, networked low-voltage HVAC controller designed for commercial comfort control, equipment management, and building automation applications.

Built for 19 VAC to 30 VAC, 50/60 Hz systems, this thermostat supports field-selectable BACnet MS/TP or N2 network communication for flexible integration into Johnson Controls and compatible HVAC control environments.

The TEC3612-14-000 provides on/off, floating, and 0-10 VDC proportional control, making it a versatile solution for fan coils, unitary rooftop units, heat pumps, cabinet unit heaters, hydronic reheat valves, and pressure-dependent VAV equipment.

Integrated temperature and humidity sensing helps maintain accurate space conditions and supports local dehumidification routines, while the full-color touchscreen interface gives operators a clear, user-friendly control point for daily HVAC operation.

Designed for commercial replacement, retrofit, and connected building applications, the TEC3612-14-000 delivers reliable Johnson Controls performance in a clean white finish.

TEC3612-14-000 is a direct replacement for TEC2616-4 ComFan Coil BACnet.
