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. Be sure to plug any large access hole in the wall
with sealer or insulation to prevent wall drafts from affecting WDU operation.
WDU Pre-wiring
The recommended wiring to the WDU from the Control Unit should be a two twisted pair
cable, 24 GA minimum. Cat 3 or 5, 4 pair cabling is acceptable. In retrofit applications the existing
thermostat wiring (a least 4 wires) may be adequate. However, such non-twisted wiring may be subject to
interference due to noise from adjacent wiring or other sources.
Wiring to the Wall Display Unit
Remote Sensor Wiring
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.
