Installation &
Maintenance Manual
Zone Interface Box supports the control of 8 zones, but during installation, any
zone of the 8 zones that is not used can be disabled through primary Wired
Remote Controller. The ON/OFF, airflow control, temperature control of a
disabled zone cannot be accessed by users and Zone Interface Box does not
process the info from a disabled zone.
A zone that has a zone motor and damper installed that is set to automatically
open when either too few zones are open or all zones are turned off. This
prevents the ducting working under excessive pressure condition and being
blown out if too many zones are closed. It also assists in keeping the air flow
ratio of the indoor unit above the minimum allowable volume. The spill zone is
usually the zone with the largest room area and the most amount of supply air
grills.
A zone without a zone motor or damper that will always deliver air to the
conditioned space whenever the system is running.
The air conditioning system requires the amount of air being delivered to the
conditioned space to be within a minimum and maximum range. As zones are
turned off, the volume of air being delivered reduces and must be kept above
the minimum airflow ratio.
The base set temperature of zoning system, set temperature of all individual
enabled zones is limited to ±3ºC from this base set temperature.
