3 stages of heating and 2 stages of cooling for Heat Pump systems. The TXB16 has a convenient setup mode from the Wall Display Unit. You can set the network address, F or C mode and easily calibrate the internal and remote sensors.
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.
Setpoint Display The displayed setpoint shows the setpoint of the current operating mode (heating or cooling) of the system. If you change modes, the setpoint displayed will change to the new operating mode setpoint. If you set the mode to AUTO mode, the setpoint displayed will be the current operating mode of the system, either heating or cooling.
If you attached a remote temperature sensor to the WDU that is set to remote sensor address “4”, you can view the outside temperature by pressing the UP and DOWN buttons simultaneously. Setup Mode The TXB16 has a new setup mode to allow the user to set the following functions from the WDU: • X10 House Code Address •...
address 1 is attached it replaces the internal sensor and is becomes the “C1” sensor. See the remote sensor section for more details. When the desired sensor is selected in the setup menu, you can adjust its displayed temperature calibration up or down 7 degrees by pressing the UP/DOWN buttons.

If the WDU detects that a sensor is not responding, it will display “SF”. In most cases this will clear itself when communications is restored to the sensor. A continuous “SF” display may indicate a problem with the wiring or the WDU itself. Check wiring and replace the WDU as needed. DCN: 141-00940-02 7/14/03...
The TXB16 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.

TXB16 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.

The TS16 WDU has an addition connector, J2, on the WDU base for connection of an external remote temperature sensor. Follow the wiring diagram with the remote sensor to connect to the WDU. DCN: 141-00940-02 7/14/03...
HVAC system but care should be taken to avoid the hot burner section or high vibration areas. Control unit wiring The TXB16 HVAC Control Unit is connected to the HVAC system and to the Wall Display Unit as well as the X10 communication interface and power connections.
