Recovery enable Range: Y or N Default: N

Note on Delta Settings : The Delta T Setting is the delta, or difference between, the setpoint and

current temp for determining when a heat or cool call comes on. The “delta” is the number of

degrees away from setpoint.

H/C Delta Range: 3 - 15 degrees. Default: 3.

Sets the minimum separation between heating and cooling setpoints. Attempts to lower the

cooling below the heating setpoint by this amount will PUSH the heating setpoint down to maintain

this separation. Same for setting the heating setpoint above the cooling setpoint, it will PUSH the

cooling setpoint up to maintain this separation.
