INTELLIZONE2 SPECIFICATION CATALOG
IntelliZone2 Confi guration cont.
Zone Priority
Comfort Mode
- A single zone call (Y1) for conditioning
will engage the compressor and allow a minimal set point
variation, thus providing ultimate comfort.
Economy Mode
- A single zone call (Y1) for conditioning
will be ignored by the IntelliZone2 until either a Y2 call
is initiated from the same zone or another zone calls for
conditioning (Y1). This allows a slightly greater set point
variation than in comfort mode. This setting prevents
less important zones from energizing the compressor
unless it is really needed, thus saving money. As a bonus
in this mode, upon a Y1 call, the IntelliZone2 may try to
precondition the zone with return air from other zones
already satisfied and, in some cases, can preclude the need
for energizing the compressor.
Variable Speed Fan Staging
- Variable Speed Fan Staging
allows the ability to expand the blower levels. Options
are Normal and Expanded. There are three airflow speeds
assigned to a compressor speed and the airflow level is
determined by the fan demand total zone %. Normal is
the recommended airflow level. Selecting Expanded will
increase the highest airflow level by one level and decrease
the lowest airflow level by one level from Normal. Not
available for single speed or dual capacity models.
Zones -
Displays the inputs that the IntelliZone2 is
receiving.
Status -
Displays the outputs that the IntelliZone2 is
sending to the equipment.
Test Mode
- In Test mode ‘Central Zone’ mode can be
selected. In Central mode all dampers are opened and
thermostat readings are taken ONLY from the Zone 1
MasterStat. This will approximate operation without a zone
system (all dampers open and IntelliZone2 MasterStat
temperature control) and can be useful during initial
construction of the home or during service etc.
Also in ‘Central Zone’ mode each damper can be
individually cycled off/on to verify operation during
Installation or service. It should be noted that the
MasterStat Z2TK troubleshooting harness can be useful
here by allowing the temporary connection of the
MasterStat directly at the IntelliZone2 relay board for ease
of configuration or servicing.
Thermostat Type

Normal
- used for normal operation
Dual Fuel
- used on dual fuel systems; needs
outdoor sensor to lockout dual fuel
