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 millivolt or other 2-wire heating systems, connect 2 wires from heating
control to R and W1.
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
