pins.
Step 12 Connect each 16-gauge wire (pre-installed on the thermostat’s high-voltage back plate)
to the matching functional wire within the JBOX, using appropriately sized wire nuts or a
NEC-approved electrical connection inside the junction box. If a site-specific wiring
diagram was provided, refer to this for wiring. If no diagram was provided, refer to Figure
7 and Table 1. (If controlling proportional valve or ECM fan, see Appendix A.) Any unused
wires must be capped according to NEC standards.

The High Voltage backplate comes with R, Switched Power 1 and Switched Power 2 jumped together with a Red
Wire nut. These can be connected to the same power source assuming all controlled Fans and Valves will be
controlled at the same voltage that will be powering the thermostat. If a different voltage will be used for any of
the Controlled elements of the HVAC then the appropriate power source should be connected to the Switched Power
1 (W1,Y1) and Switched Power 2 (G,O,W2) terminals.
