TEC26x6 Series
BACnet® MS/TP Networked Thermostat Controllers with Dehumidification Capability, Fan Control,
and Occupancy Sensing Capability
Description
The TEC26x6(H)-4 and TEC26x6H-4+PIR Series Thermostat Controllers are BACnet® Master-Slave/Token-Passing (MS/TP) networked devices that provide control of twoor four-pipe fan coils, cabinet unit heaters, or other equipment using on/off, floating, or proportional 0 to 10 VDC control input, three speeds of fan control, and dehumidification capability. The TEC26x6H-4+PIR Series Thermostat Controllers have occupancy sensing capability built into the device. These devices maximize up to 30% energy savings in high-energy usage light commercial buildings, such as schools and hotels, during occupied times by using additional Stand-By setpoints.
The technologically advanced TEC26x6(H)-4 and TEC26x6H-4+PIR Series Thermostat Controllers feature a Building Automation System (BAS) BACnet MS/TP communication capability that enables remote monitoring and programming for efficient space temperature control. Specific models are available to accommodate commercial and hospitality applications.
The TEC26x6(H)-4 and TEC26x6H-4+PIR Series Thermostat Controllers feature an intuitive User Interface (UI) with backlit display that makes setup and operation quick and easy. The thermostats also employ a unique, Proportional-Integral (PI) time-proportioning algorithm that virtually eliminates temperature offset associated with traditional, differential-based thermostat controllers.
Refer to the TEC26x6(H)-4 and TEC26x6H-4+PIR Series BACnet MS/TP Networked Thermostat Controllers with Dehumidification Capability, Fan Control, and Occupancy Sensing Capability Product Bulletin (LIT-12011587) for important product application information.

Features
•BACnet MS/TP communication — provides compatibility with a proven communication network; BACnet MS/TP is widely accepted by Heating, Ventilating, and Air Conditioning (HVAC) control suppliers
•onboard occupancy sensor (Passive Infrared [PIR] Models) — provides energy savings without additional installation time and cost
•password protection option — protects against unwanted thermostat controller tampering
•integral humidity sensing capability (dehumidification models) — increases occupancy comfort by providing dehumidification
•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
•three speeds of fan control — provide easy FAN speed selection via the interface key, to meet the application requirements
•single/dual setpoint adjustment — enables user setpoint options to accommodate application
•override interface key (commercial models)
— allows easy access for temporarily overriding the unoccupied mode
•temperature scale selector key (hospitality models) — offers guests the ability to select a Fahrenheit (°F) or Celsius (°C) temperature scale display
•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
Repair Information
If a TEC26x6(H)-4 or TEC26x6H-4+PIR Series Thermostat fails to operate within its specifications, replace the unit. For a replacement thermostat, contact the nearest Johnson Controls® representative.
