371 PropertyList
*1 The PresentValue property cannot be set to a value greater than the value of the MaxPresValue property (PropertyID: 65). Change the
value of the MaxPresValue property according to the maximum value to be set for the PresentValue property.
Reliability=2(OverRange) if Reliability is 0 when PresentValue changes from within the range of MaxPresValue to out of the range of
MaxPresValue.
Reliability=0(NoFaultDetected) if Reliability is 2 when PresentValue changes from out of the range of MaxPresValue to within the range
of MaxPresValue.
When Reliability is other than the above, the value of Reliability does not change. The same applies when OutOfService changes from
TRUE to FALSE and the buffer memory is updated.
(Reliability=1 remains if Reliability is 1 when PresentValue changes from within the range of MaxPresValue to out of the range of
MaxPresValue (or reverse order).)
*2 Only ANSI/ASHRAE Standard 135-2016 and ANSI/ASHRAE Standard 135-2012 are supported.
