NOTES:
1. Transformer Common connection not required for battery-only operation of thermostat.
2. Second Stage Control connections not used for single stage heating or cooling systems.
3. For units requiring reversing valve to be energized during heating, connect reversing valve to B
terminal. For units requiring reversing valve to be energized during cooling, connect reversing valve
to O terminal. 4. Required for units with 2 stage heat only. 5. For 2 stage heat units not having a
separate Emergency Heat Terminal, add installer supplied jumper. 6. Remote Sensor Terminals can
