INTRODUCTION
The Zone Comfort system is a heating
and cooling system that enhances
comfort and improves efficiency by giving
more control over the distribution of
conditioned air. Homeowners enjoy
many benefits such as healthy indoor air,
comfortable basements and cool
summer evenings. Multiple thermostats
provide the means to zone the home by
section or level in order to gain more
control. This will virtually eliminate over
or under conditioned spaces as is
common in a lot of homes today.
The Zone Comfort system is designed
for use in hydronic (boiler) systems or
combination space and water heating
systems (Combo Systems). Combo
heating systems use the home’s water
heater to provide both the space heating
and domestic hot water, eliminating the
need for a furnace. The equipment can
be configured for heating only, heating
and cooling or cooling only applications.

systems to be connected to a heat pump.
The Zone Comfort duct system can be
much smaller than conventional ducting
making it ideal for retrofit applications or
where a conventional duct system would
result in unsightly bulkheads and wasted
space.
When used as the warm air distributor of
a boiler heating system the Zone
Comfort air system can provide
warmer more comfortable air
temperature than a gas furnace with less
noise and much smaller duct
requirements. This is ideal for large
custom homes where a premium heating
product is required that is quiet,
comfortable and out of sight.
Controls usage and settings are covered
in a separate document.
HOW IT WORKS
The key to the Zone Comfort system is
the level of comfort and efficiency
provided by the unique control system.
Zone dampers in the air handler operate
to increase or decrease the capacity in
each zone of the house as needed.
Heating and cooling air flow for each
zone can be set by the installer to
customize every installation.
Cooling mode uses a fixed or automatic
strategy to maximize homeowner
comfort. In auto mode, blower speed is
carefully controlled to optimize
dehumidification. When cooling demand
is low (determined based on the number
of zones calling or on the measured
supply air temperature) the blower runs a
little slower. The air has more residence
time in the evaporator coil. This results
in removing more moisture from the air,
thus maintaining the humidity in an
optimum range.
Zone One
The primary or master or zone one tells
the air handler whether it is heating
season or cooling season or if
continuous air circulation is desired. Any
zone can be zone one but it is typically
