  • Page 2: Control Buttons

    1. TX15 OPERATION The TX15 series thermostats provide typical thermostat functions as well as the capability to receive X-10 powerline carrier signals. The X-10 commands allow for the thermostat’s Setpoint, Mode and Fan functions to be changed remotely. In addition, the TX15-B series has bi-directional capability and can also transmit information by X-10 commands using an extended X-10 command set.
  • Page 3 button is released. After 3 seconds of no activity, the LCD display will change back to show the current temperature and the new setpoint value will be transmitted to the Control Unit. The setpoint can be set from 40F to 99F ( 5C to 37C). There is only ONE setpoint for the WDU, and it is used for both heating and cooling.
  • Page 4 How to enter the Calibration Mode and view the Calibration Offset. To enter into the calibration mode, FIRST press and HOLD the “MODE” button and then simultaneously press the “FAN” button until “CO” appears on the LCD display. Release the buttons and the current calibration offset number will appear on the LCD display. This is usually “0”...
  • Page 5 This changeover difference of two degrees on the first call helps to prevent the system from overshooting and oscillating between heating and cooling. Changes from cooling to heating works similarly, with the two degree changeover difference being two degrees below the setpoint. Standard System Mode Selection.
  • Page 6 Status LED The Control Unit has a Status LED on the circuit board that will normally blink on and off slowly as a system heartbeat. During short cycle protection delay periods, the LED will blink twice for each heartbeat. This indicates that the compressor is locked out during this time. X-10 Interface The TX15 Control Unit has an X-10 powerline carrier interface that allows X-10 commands to be received over the 110 VAC powerline.
  • Page 7 2. TX15 INSTALLATION STOP Before proceeding with removing an existing thermostat and installing the TX15, Read the following important steps. 1. Record existing wiring information on the enclosed wiring form. 2. Perform the TX15 bench test in Section 3 3. Check WDU wiring BEFORE applying power to control unit. 4.
  • Page 8 TX15 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.

  • Page 9: Control Unit Wiring

    TX15 CONTROL UNIT INSTALLATION Location and Mounting. Install the TX15 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 areas.

  • Page 10: Power Connection

    Wiring to the PSC05 X-10 Interface Module The X-10 interface on the Control Unit is the RJ11 jack, J2. It is connected to an X-10 power line interface module, Model PSC05, by the four (4) wire modular phone cable provided. TX15 CONTROL UNIT 120V OUTLET PSC05...

  • Page 11: System Checkout

    3. SYSTEM CHECKOUT It is strongly recommended that you hook-up and run a simple bench test before installing the TX15. Not only will this save you time in system checkout but will also familiarize you with the thermostat’s operation. THERMOSTAT BENCH TEST NOTE: Remote sensor versions REQUIRE the remote sensor to be connected to the WDU in order to work.
  • Page 12 HVAC SYSTEM TESTING The TX15 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.
