NOTE 1: The Service status point represents general Check status. If this is point is 1, the user can find out the actual failing
condition by polling point 38 to 42. If this point is 0, points 38 to 42 will also be 0.
NOTE 2: All of the ADI and BD points support the override function. The value overridden will be stored permanently, so the
status 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 and BD points 15 through 24.
In the case of loss of communications for 15 minutes (i.e., if the controller is not addressed for 15 minutes), the
controller will revert BD points 15 through 24 to zero value (make them all local requests).
NOTE 4: 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 5: If the temperature in programming step #4 is set to be displayed in degrees Fahrenheit, the values of ADI 7, ADI 21
through ADI 28 and ADI 32 will be Fahrenheit values. If the temperature is set to be displayed in degrees Celsius,
these ADI values will be in Celsius.
