0=OK, 1= Check DI2

NOTE 1:
The Service status point represents general Check status, if this is point is 1, then by polling point 37 to 41 the user
can find out actual failing condition. If this point is 0 then points 37 to 41 will be also 0.
NOTE 2:
All of the ADI and BD points support the override function. The value overridden will be stored permanently, so the sta-
tus attribute will never have any override active status. Because none of these points support the override release function, the
controller will acknowledge the override release function but never release the value. The controller will respond with NAK error
N10 if the value for the override command is outside the limits for that point. Points that are "Read Only" can not be overridden.
The controller will acknowledge the override command, but the actual change will never happen.
NOTE 3:
All of the points in this map can be adjusted through the keypad except: “Read Only” points, ADI 32, and BDpoints 17
through 26. In the case of loss of communications for 15 minutes (i.e., if the controller is not addressed for 15 minutes), the con-
troller will revert BD points 17 to 26 to zero value (make them all local requests).
NOTE 4:
ADI point 32, Outdoor Air Temp., can be overridden for a default of 10 minutes. After 10 minutes it reverts back to its
original port value.
NOTE 5:
Communications are disabled when programming mode or clock/schedule mode is entered via the keypad. Entering
programming mode via the keypad can be disabled.
NOTE 6:
0-150 number represents 0.0 to 15.0°F.
