4 In case of a multiple AHU Kit combination within one refrigerant system, those kits must share the same AHU housing
including fan, and they have to be "group-wired" and operate as a single group. In this case you have to disconnect the
included remote controllers and CZ-CAPBC2 boards (ACC-SP1A PCB) except for one each. It is irrelevant which one is
retained, there is no preference. The external connections need to be done only on the unit with the connected CZ-CAP-
BC2 board.
Note: In this particular case it is even possible to combine a single advanced or medium version with one, two or three
light versions, and still have full functions of the advanced or medium version respectively.

PAW-160MAH2(L/M) can be installed in combination with all ECOi outdoor units (including Mini ECOi
(2-pipe), ECOi 2-pipe and ECOi 3-pipe units) like any other standard indoor unit.
Mixed installation with standard indoor units is possible with all ECOi outdoor units (as above). However,
in this case one additional RAP valve (CZ-P160RVK2) must be installed in the unit connection pipe,
unless the complete system is exclusively used in cooling only operation.
PAW-280MAH2(L/M) can be installed in combination with all ECOi outdoor units (including Mini ECOi
(2-pipe), ECOi 2-pipe and ECOi 3-pipe units) with a nominal cooling capacity of at least 8 HP like any
other standard indoor unit.
Mixed installation with standard indoor units is possible with all ECOi outdoor units (as above). However,
in this case two additional RAP valves (2 x CZ-P160RVK2) must be installed in the unit connection pipe,
unless the complete system is exclusively used in cooling only operation.
When PAW-280MAH2(L/M) is installed in combination with an ECOi 3-pipe outdoor unit, either two
16 kW solenoid valve kits or two ports of a 16 kW multi-port heat recovery box respectively (CZ-P...HR3)
need to be used in parallel installation for each AHU DX coil.
Mixed installation with standard indoor units is not allowed.
Connection to ECOi 3-pipe systems is not allowed.
