Compatible Air Conditioning Units.
○ up to two wire remote controllers (PC-ARFG2-Z), one installed to ZIB and one to indoor unit E-BOX.
○ up to eight zone motors and thermostats.
○ up to two remote temperature sensors.
4. The Wired Remote Controller connected in Zoning Kit can only connect to one Indoor Unit.
5. Remote Sensors must not be connected to Indoor Unit PCB. To enable correct operation and
sensing, the remote temperature sensors must be connected to the Zone Interface Box.
6. Careful attention must be given to ensure that the air flow rate through the indoor fan coil unit is
within the allowable range as specified in the technical data manuals.
7. The zone damper motors must be connected to respective terminals in the Zone Interface Box.
8. Under certain conditions in the cooling cycle - particularly when the air flow rate is low, the
temperature of the supply air may reduce to a level that
may cause condensation on the indoor unit and/or the
duct and fittings. Due care must be taken to ensure that
the condensate does not drip onto the ceiling or into
the conditioned space. Additionally, it is recommended
that a safety drain tray be installed under the indoor
