On a SIM-MTECH, the 'Space Static Pressure Setpoint' does not map from the McQuay controller accurately.


Using the SIM-MTECH manual (F-26133-2) for reference, the Read/Write range of "Space Static Pressure Setpoint' on page A-45 displays as 0 to 5.0 "WC.  But the displayed setpoint does not match the value in the McQuay controller.  And, in general terms, any space static is never as high as 5.0 "WC.

The manual contains a typo.


The above-mentioned space static pressure setpoint range is actually -0.25 to +0.25 "WC.

Keep this in mind as calculations are done to convert the unitless range of 0-250 to a value in "WC.
