changes are required, refer to APPENDIX A for wiring configurations and skip to
"Install Mounting Plate".
When replacing a thermostat and replication of the existing wiring is desired on
the BDXCTSH1 Thermostat, the following applies:
• Remove old thermostat to expose the wiring terminals
• Photograph the wiring for reference or,
• Use the Wire Color Record to note the wire color and function of each wire.
If the terminals of the existing thermostat are unmarked, determine the
wire functions for each color wire at the appliance.
