The terminologies used in this specication are as following:
Terminology Denitions
Enable/Disable Zone
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, airow 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.
Spill 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 o. 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 ow
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.
Common Zone
A zone without a zone motor or damper that will always deliver air to the
conditioned space whenever the system is running.
Minimum Airow Ratio
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 o, the volume of air being delivered reduces and must be kept above
the minimum airow ratio.
Base Set Temperature
The base set temperature of zoning system, set temperature of all individual
enabled zones is limited to ±3ºC from this base set temperature.
