Reversing Valve O/B |
0 = O (O/B in Cool. O wire is connected to the O/B terminal and controls cooling.) 1 = B (O/B on Heat. B wire is connected to the O/B terminal and controls heat.) The literature that came with your heat pump equipment should indicate whether the reversing valve is energized in Heat or Cool mode. |

Built-in Compressor Protection
Damage can occur if your system’s compressor is restarted too soon after shutdown. This feature forces the compressor to wait for a few minutes before restarting. During the wait time, the display will show the message Waiting For Equipment under the room temperature reading.
When the safe wait time has elapsed, the message disappears, and the thermostat will show “Heat on” or “Cool on”.
