Matching outdoor unit capacity with AHU Kit capacity
Matching outdoor unit capacity with AHU Kit capacity – PACi and PACi NX
systems
NX
As the AHU Kit model PAW-280PAH3M-1 has only one fixed capacity and can be combined with
the complete range of PACi and PACi NX systems, where outdoor unit capacities vary from 2.5
(PACi NX range) to 25 kW (PACi range), it is necessary to change the settings so that the de-
fault capacity check of the PACi or PACi NX outdoor unit is ignored or the outdoor unit capacity is
matched with the AHU Kit capacity.
There are four different methods to achieve this aim.
Method A: Cutting JP001 to ignore capacity
One possibility is to cut jumper JP001 on the outdoor unit main PCB.

Important
Method A is only applicable to the following combinations of PACi outdoor units and AHU Kits:
To cut jumper JP001 on the PACi outdoor unit main PCB, complete the following steps:

1. On the PACi outdoor unit PCB, cut the wire of jumper JP001 at two positions, and take the cut
2. Place a NOTE label, which indicates that the jumper wire has been cut, in the following
