Applications
The TEC3000 Series On/Off or Floating Fan Coil and Individual Zone Thermostat Controllers are stand-alone and
field-selectable BACnet® MS/TP or N2 networked devices that provide control of the following:
•
local hydronic reheat valves
•
pressure-dependent variable air volume (VAV) equipment with or without local reheat
•
two- or four-pipe fan coils
•
cabinet unit heaters
•
other individual zone equipment using an on/off or floating control input
The networked models feature a field-selectable Building Automation System (BAS) BACnet MS/TP or N2
communication capability that enables remote monitoring and programming for efficient space temperature control.
All models include a USB port configuration that reduces installation time by allowing simple backup and restore
features from a USB drive, which enables rapid cloning of configuration between like units.
Some models have occupancy sensing capability built into the device. These thermostat controllers maximize up to
30% energy savings in high-energy usage commercial buildings, such as schools and hotels, during occupied
times by using additional standby setpoints.
All models feature an intuitive onboard touchscreen UI with backlit display that makes setup and operation quick
and easy. Multiple fan configurations are supported for fan coil equipment types:
•
single-speed
•
multi-speed (two or three discrete speeds)
•
variable-speed/EC motors (0 to 10 VDC control)
Some models support dehumidification on two-pipe fan coil units with reheat, and four-pipe fan coil units with or
without reheat. When no heating is required, the thermostat controller monitors space humidity and activates
dehumidification control as necessary. Heat and/or reheat is used as required to maintain the space temperature.
For optimal dehumidification performance, use a fan coil unit that has a multi-speed or variable-speed fan (VSF).

Page 20: Selecting The Heating And Cooling Device Type
Selecting the Heating and Cooling Device Type By default, the thermostat is configured for On-Off (2-position) control. This can be changed to Floating (Incremental) mode when the Unit Type is not set to VAV. For VAV mode, only floating actuators are supported and this option is unavailable. -
Page 21: Setting The Control Mode
For VSF control, the output is configurable for any range between 0 V and 10 V. The parameters are Start Voltage, Full Speed Voltage, and Minimum Command. Start Voltage is the voltage output at which the fan begins running, and Full Speed Voltage is the voltage output at which the fan reaches full speed. Minimum Command is the percentage of the range between the Start Voltage and the Full Speed Voltage. -

Page 23: Dehumidification Control - Fan Coil Only
For automatic changeover, a supply temperature sensor or switch must be connected to the Changeover Sensor (COS) input of the TEC. Changeover Mode must be set to Auto, and Supply Temp Type must be set for Analog Sensor, Cooling N.C. (cooling when switch is closed), or Heating N.C. (heating when switch is closed). When an analog sensor is used, the changeover setpoint can be adjusted. -

PID is used in conjunction with a Multi-Stage Controller (MSC) for all occupied and standby control. Additionally, the PID features Johnson Controls proprietary PRAC+ (Pattern Recognition Adaptive Control) automatic tuning, which continuously tunes the controller parameters to automatically optimize the control performance to match the equipment and zone. -
Page 31: Configurable Binary Inputs
PRAC+ automatic tuning can also be disabled. When disabled, the controller parameters remain at their last values until automatic tuning is re-enabled. To disable automatic tuning: 1. Press the Menu icon. 2. Press Control Setup. 3. Press Tuning. 4. Press Temp Control Setup. 5. -
Page 32: Aux Control
The Open Door option works in conjunction with a motion sensor, either built into the TEC or connected to another BI configured for Motion NO/NC mode. When the door is open, motion detected by the sensor is ignored. Note that opening the door does not stop an Occupied period started by the motion sensor prior to opening the door. -
Page 33: Commissioning Mode
Commissioning Mode The thermostat controller has a built-in commissioning mode, which is designed to allow you to quickly test equipment wiring and functionality. Commissioning mode temporarily disables the control logic, and allows you to manually command any individual output. Commissioning is designed to be the last step of the installation process after configuring the controller for the equipment being controlled, and the available options in commissioning mode are dependent on the controller configuration. -
