Air flow setpoint

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

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

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


Depending on the input "EffManSwCmd_MSt" the air flow setpoint will take the following values.


EffManSwCond_St

air flow setpoint

1 = off

0

2 = on-low

AirFlow_Sp_Low

3 = on-high

AirFlow_Sp_High

4 = auto

AirFlow_Sp


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

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