F9DX : High Pressure/Flow Cutback
- Mix chamber is too large for set pressure
- Set pressure is too high for given mix chamber
Reference the pressure/flow performance chart in the operation manual and decrease the mix chamber size or set pressure accordingly.
- Applies to Advanced Display Module (ADM) software 16N725 (all versions) and 17A157 (version 1.01.001 only)
- For these specific software realeases, the causes for the codes F9DX, T3NM and T3CM were combined and all triggered the code F9DX. ADM software more recent than 17A517 1.01.001 splits these three codes apart.
- For all causes/solutions, see T3NM and/or T3CM.
