Connecting AHU systems via the AHU Kit to ECOi/ECO G or PACi outdoor
units
The following graphic shows an example for connecting a third-party air handling unit via the
Panasonic AHU Kit to Panasonic ECOi/ECO G or PACi outdoor units.
PACi or ECOi/ECO G outdoor unit
Demand control on the outdoor unit
managed by external 0–10 V signal
Air Handling Unit (AHU)
AHU control kit
External BMS
0 – 10 V capacity control
1 This schematic layout applies to the advanced AHU Kit version only, because it features an in-built CZ-CAPBC2
interface handling the 0–10 V control. This enables two control alternatives:
● Capacity control through external BMS via 0–10 V signal
● Capacity control through in-built supply air or ambient temperature sensor
2 As the “light” version of the AHU Kit does not include an in-built CZ-CAPBC2 interface for handling the 0–10 V con-
trol, this schematic layout does not apply to the “light” AHU Kit version.
