Air inlet
Check air volume at each air outlet when R1-R4 is full open and set static pressure as target value. Then, analog
input to keep the static pressure at this target value even when either of the damper closes.
With MAC-397IF-E as in section 2-2, it is also possible to stop the indoor unit when all duct damper closes.
*Refer to the 1-3 for air volume differentials to prevent hunting.
