Wall Display Unit Installation
For retrofit installations, install the WDU at the existing thermostat location. You may reuse the existing
thermostat wiring (4 wires required).
For new installations, be sure to locate the WDU in a location for best temperature sensing in the area to
be controlled. Avoid these locations:
• Outside walls
• Drafty locations
• Direct sunlight exposure
• Near HVAC vents
• Corners or behind doors
Install the WDU
• Mark the location of the installation holes
• Install the screw anchors
• Run wiring through the back plate
• Install the back plate on the wall with the screws provided.
• Connect wiring to terminals. CAUTION! Double check your wiring. Mis-wiring the WDU can
result in damage to the unit.
• Write down the terminal wiring colors for connecting the WDU cable on the HVAC Control Unit
end.
WDU Wiring to HVAC Control Unit
Remote Sensor Connection
Two remote sensors can be connected to the TR60 Wall Display Unit.
• Sensor S1 will replace the internal sensor
• Sensor S2 will be averaged with the internal sensor
or Sensor S1 if attached
• Use only RCS 10K Thermistor style sensors
4 wire connection is required back
to the HVAC Control Unit. Existing
thermostat wiring can be used.
For new construction, thermostat
wire or Cat 5 wire can be used.
