Wayne-Dalton WDTC-20 Cross Reference Chart, Installation, Modify Label Scheme, Your Wires

Step 6: Modify Label Scheme

If your combination of wires is not shown, refer to the cross reference chart below. Add the corresponding Wayne-Dalton terminal designation label to your wire’s label and then repeat Step 5 to match your wiring diagram. If a match is still not successful, contact customer support at 1-866-545-5765, e-mail at homesettings@wayne-dalton.com or contact your HVAC professional.

Note: The C wire (24 Volts AC) is not optional. If a C wire is not present, your Z-Wave®Enabled Thermostat will not operate, contact customer support for options.
