Change NHC board
Check inverter box
Defect

Replace
Check and re-configure if necessary according to installation type parameters:
- Check that Parameter Unit size [P802] is equal to 17kW or 21kW according to unit
- Check that Parameter Supply type [P808] is equal to ‘3 Phase’
- Check the value of Parameter Inverter CDU Capacity [P306] is in accordance with Parameter Unit Size [P802]
- Check that Parameter Unit Type [P801] isn’t in ‘Cooling Only’ when DHW mode is configured Domestic Hot Water Type [P710] > 0
- And check that Parameter Unit Type [P801] is defined: [P801]
≠ 0
- Check that Parameter Header / Follower Selection aren’t [P742] > 0 when parameter Domestic Hot Water Type is [P701] > 0 (and
reverse). Because DHW and Header / Follower features are not compatible
- And check that Parameter Follower [P743 to P745] are defined when Parameter Header / Follower Selection is {P742] = 1
Check Parameter 344 inv_err
Check that Parameter Unit size [P802] is equal to 17kW or 21kW
