Design Features
Full Color Touchscreen Display and
Diagnostic LEDs
With traditional zone control systems, the installer typically
has a difficult time determining the status of the inputs and
outputs of the zone control board. The IntelliZone2 System
employs an LED for each output and the MasterStat color
display shows all inputs and outputs. With just a glance,
the installer is able to quickly determine what inputs the
IntelliZone2 is receiving and what outputs the IntelliZone2
is sending to the unit.
Application Flexibility
• Multiple level zone calls communicate exact zone load
requirements for intelligent equipment control.
• Controls up to six zones with variable speed compressor
(four with dual-capacity and two zones with single-
speed compressor).
• Control of ECM blower motor to match needs of the
space. Six/eight blower speeds are available at all times.
• Zone size as small as 15% of whole house with
variable speed compressor (25% dual-capacity and 50%
single speed).
• Individual zone-selectable economy or comfort modes.
• Four staging options (normal, quicker, faster1 and
faster2) to allow a wide range of comfort and energy
consumption solutions.
• Separate staging options for heating and cooling
provides better comfort.
• Dehumidification mode lowers airflow in cooling for
better dehumidification.
• Simple, reliable thermostat operation; simple
programming for the homeowner.
IntelliZone2's Sophisicated Microprocessor Control
with LEDs to Display Inputs and Outputs
• Individual zone-selectable continuous or
intermittent blower.
• Smart algorithm serves simultaneous heating and
cooling demands.
• Reduces blower power consumption.
• Installation and Service Advantages
• Bypass damper not needed (minimal oversizing of
ductwork may be desired).
• All low voltage wiring (24VAC).
• Central mode control for temporary conditioning of the
whole house using one thermostat.
• Low cost communicating zone thermostats.
• Three-wire or two-wire damper actuators for maximum
performance and reliability.
• Transformer with integrally mounted circuit breaker.
• LED indicators (damper operation, mode, fault) and
troubleshooting screens displayed on MasterStat for
easy diagnostics.
