CZ-T10
Panasonic has developed an optional accessory (consisting of plug wires) called CZ-T10 to enable an easy connection to this T10 connector.
Connecting an ECOi indoor unit to an external device is easy. The T10 terminal featured in the electronic circuit board of all indoor units enables digital connection to external devices.

Fan drive connector (CN032).
PAW-FDC
Panasonic has developed an optional accessory (consisting of plug wires) called PAW-FDC to enable an easy connection to this fan drive connector (CN032).
Operating the ventilation fan from the remote controller:
Start / stop of external ventilation and total heat exchanger fans. Works even if indoor unit is stopped. In case of group control > all fans will operate; no individual control.
