Pressure setpoint

Connect the input "EffManSwCmd_MSt" to the output of the plant strategy macro.

This output considers the time schedule, the external overrides and the wall modules settings.

In this case you should not connect the  "EffManSwCmd_MSt" to the fan "ManSwCond_MSt" input.


Depending on the input "EffManSwCmd_MSt" the static pressure setpoint will take the following values.


EffManSwCond_MSt

pressure setpoint

1 = off

0

2 = on-low

DuctPressSpLow

3 = on-high

DuctPressSpHigh

4 = auto

DuctPressSp


If you need only two setpoints, connect one of them to two inputs.

E.g. If you only want to switch to low pressure with the wall module, connect the setpoint "DuctPressSp" to both the normal setpoint and high setpoint inputs. See next table:
