  • Page 2 It supports 3 stages of heating and 2 stages of cooling for Heat Pump systems. The TU16 has a convenient setup mode from the Wall Display Unit. You can set the network Unit ID, F or C display mode and easily calibrate the internal and all attached remote sensors.

  • Page 3: Lcd Display

    TS16 Wall Display Unit The TS16 Wall Display Unit has a LCD display and control buttons for changing the setpoint, system operating mode and manual fan mode. The WDU also has an internal temperature sensor. The display serves as a common display for many functions. It normally shows the current room temperature but switches to show setpoint, mode or other functions when buttons are pushed.

  • Page 4: Control Buttons

    Control Buttons Setpoint UP and DOWN Buttons The UP and DOWN buttons control the heating or cooling setpoint temperature. To View The Current Setpoint: Push either the UP or DOWN buttons once will cause the LCD display to change to show the current setpoint temperature (but won’t change it). To Change The Setpoint: With the setpoint displayed as above, push the UP button to increase the setpoint temperature by one degree or push the DOWN button to decrease the setpoint by one degree.

  • Page 5: System Setup Mode

    Setting the Fahrenheit or Celsius mode In the setup mode, press the mode button to select “FC” mode. The TU16 is default set to F mode. To change the degree mode, press the UP/DOWN buttons to select F or C as desired. To exit press mode again to move another setup mode or wait for the screen to time out and return to the normal thermostat temperature display.

  • Page 6: Remote Sensors

    You can view the outside temperature by pressing both the UP/DOWN buttons simultaneously. Display Lock The TU16 WDU control buttons can be locked to prevent unauthorized changes in system operation from the WDU. The display lock/unlock state can only be set by the “DL” network command. See the Serial Protocol Manual for details on this command.

    UPB powerline network. The TU16 Control Unit connects to the HVAC system the same as, and in place of, a standard thermostat. It is usually mounted near the HVAC system, although it can be mounted anywhere convenient. It is connected to the WDU by a 4 wire cable, either standard thermostat wiring or typically Cat 3/5 in new construction.
  • Page 8 G, W1, W2 HEAT PUMP HVAC SYSTEM OPERATION The TU16 has Heat Pump operating modes of Heating, Cooling, Auto changeover and Emergency Heat. The Heat Pump HVAC system operation is the same as for Standard systems for normal first and second stage operations.

  • Page 10 UPB Thermostat Setup Program can set the network address, either directly or via a device setup mode. Unit ID The TU16 UPB Unit ID address can be set directly from the Wall Display Unit and also by the network configuration tool.
  • Page 11 For the complete UPB thermostat protocol, please refer to the RCS UPB Thermostat Protocol Manual, document number 150-00205. The TU16 has two UPB operation Modes, Link and Message. Link mode is a simple table of UPB Link addresses mapped to thermostat modes or setpoints. Message Mode is a more robust protocol of commands and messages designed for thermostats.

    TU16 Installation STOP Before proceeding with removing an existing thermostat and installing the TU16, Read the following important steps. 1. Record existing wiring information on the enclosed wiring form. 2. Perform the TU16 bench test 3. Check WDU wiring BEFORE applying power to control unit.
  • Page 13 TU16 Wall Display Unit Installation WDU Location Choose a location that best represents the temperature of the area to be controlled. Avoid locations that are subject to drafts, from doors and windows, or areas with direct sunlight exposure. WDU Mounting Route the wires to the WDU through the access hole in the back of the case. Mount the WDU to the wall with the screws and anchors provided.

    TU16 Control Unit Installation Location and Mounting Install the TU16 Control Unit in a protected, convenient, INDOOR location near the HVAC system or in a service accessible area such as an equipment closet or garage. Mount the Control Unit in a vertical position on a wall or sturdy structural member. The unit may be mounted on the HVAC system but care should be taken to avoid the hot burner section or high vibration fan areas.

This type of a system requires that the TU16 Control Unit be connected using a separate heating system power input R terminal (RH) and a separate cooling system power input R terminal (RC). When connecting to these systems you must “split”...
