ZONING DATA – This screen and its sub-screen ZONE
MODULE STATUS (accessible by pressing the key when
in the ZONING DATA screen) provide important information
to help confi rm proper installation and setup of an iQ Zone
system. Among other things, the ZONING DATA screen shows
the numbers of the zones which are active (open and in use)
and the weighting assigned to each zone.
Press the key to view ZONE MODULE STATUS. During zone
system setup this screen will indicate which zone modules are
detected in the zone system communication network, which
zone each module is associated with, and any damper motor
issues. After installation of an iQ Zone system, this screen is
essential to confi rm that all module assignments have been
made and detected correctly.

and considered for adjustment if desired by the installer,
including:
- minimum heat pump operating temperature
- autochangeover
time
• settings which are recommended to be done by the installer,
including:
- setting date and time
• options and features which are recommended to be set with
the homeowner’s oversight, including
- selection of programmable schedule versus non-
programmable

including
- how to disable or re-enable zone control

- settings typically made at the iQ controller which do not
apply with an iQ Zone system (with zone control enabled)
- settings associated with an iQ Zone system (with
zone control enabled) which are entered at local zone
thermostats, not from the iQ controller
The above settings are described below:
Minimum Heat Pump Operating Temperature
This is the outdoor temperature (measured beneath the outdoor
unit control panel) below which, when heating is called for, the
heat pump will not operate and backup heat means (electric
heat or gas furnace) will take over. The ideal temperature
setting is the “balance point” below which it would be more
