Johnson Controls TEC21x7-4 Series N2 Networked Thermostat Controllers with Two Outputs

N2 Networked Thermostat Controllers with Two Outputs
TEC21x7-4 Series

The TEC21x7-4 Series Thermostat Controllers are N2 networked devices that provide control of local hydronic reheat valves, pressure dependent Variable Air Volume (VAV) equipment with or without local reheat, or other zoning equipment using an on/off, floating, or proportional 0 to 10 VDC control input. The technologically advanced TEC21x7-4 Series Thermostat Controllers feature a Building Automation System (BAS) N2 Bus communication capability that enables remote monitoring and programming for efficient space temperature control.

The TEC21x7-4 Series Thermostat Controllers feature an intuitive User Interface (UI) with backlit display that makes setup and operation quick and easy. The thermostat controllers also employ a unique, Proportional- Integral (PI) time-proportioning algorithm that virtually eliminates temperature offset associated with traditional, differential-based thermostat controllers.

• BAS N2 open communication — provides compatibility with a proven communication network; N2 Bus is widely accepted by Heating, Ventilating, and Air Conditioning (HVAC) control suppliers
• password protection option — protects against unwanted thermostat controller tampering
• backlit Liquid Crystal Display (LCD) — offers real-time control status of the environment in easy-to-read, English plain text messages with constant backlight that brightens during user interaction
• on/off, floating, or proportional 0 to 10 VDC control — offers additional application flexibility by providing more advanced control signals
• override interface key — allows easy access for temporarily overriding the unoccupied mode
• simplified setpoint adjustment — enables the user to change the setpoint by simply pressing the UP/DOWN arrow keys
• two configurable binary inputs — provide additional inputs for advanced functions such as remote night setback, service or filter alarms, motion detector, and window status
• over 20 configurable parameters — enable the thermostat to adapt to any application, allowing installer parameter access without opening the thermostat cover
• optional discharge air sensor — monitors unit efficiency
