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 6: Remote Sensors
Remote Sensors The TS16 Wall Display Unit has a remote sensor terminal block, J2, on the base for connection of a remote temperature sensor. Without any remote sensor attached, the WDU uses the internal sensor for the current temperature information. When a remote sensor is attached, the WDU will detect it automatically and will use the remote sensor(s) according to its address selection. -

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. - Page 8 Be sure to check your HVAC system’s requirements. Note: Dipswitch SW1 position 3, the CO selection is not required for standard systems. Leave in the Off position (SW1-3 = OFF) TXB16 Control Unit HVAC System Outputs for Standard Systems Operating Mode Outputs (no Fan with Heat)
- Page 9 HEAT PUMP HVAC SYSTEM OPERATION The TXB16 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. In addition, Heat Pumps may have a third stage of heating, which is for heat strips. The third stage comes at 5 degrees from setpoint and stays on until the stage 1 setpoint is satisfied.
- Page 10 Status LED X10 Signal Reception or Transmission Indication When the TXB16 is first powered up, the status LED will come ON steady, indicating power and the unit is running OK. When the X10 power line interface is connected and an X10 signal is detected, the LED will start flashing slowly as the normal system heartbeat.
- Page 11 X10 House Code Setting New with the TXB16, the X10 House Code address, is now set from the Wall Display Unit. (If your unit includes X10 address dipswitch SW1, with positions 5, 6, 7 and 8, ignore them as they are no longer used for address selection.

- Page 13 TXB16 Installation STOP Before proceeding with removing an existing thermostat and installing the TXB16, Read the following important steps. 1. Record existing wiring information on the enclosed wiring form. 2. Perform the TXB16 bench test 3. Check WDU wiring BEFORE applying power to control unit.
- Page 14 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.

HVAC SYSTEM TESTING The TXB16 Control Unit connects to the HVAC system at the normal thermostat connections on the HVAC unit. Standard thermostat control of HVAC systems consist of 24VAC contact closures in the thermostat. You can verify that your HVAC system is working correctly by duplicating the contact closures by shorting across the proper terminals at the HVAC system’s thermostat connection. - Page 22 TXB16 Wiring Diagram TXB16 CONTROL UNIT Fuse Mini ATO S2 2 2 Amp TS16 OFF ON WALL DISPLAY UNIT RH=RC Cut Jumper to split HVAC SYSTEM +12VDC +V Blue 24V COM STATUS THERMOSTAT CONNECTOR CLOCK 24V RH C - 24VAC Common...
