The Synergy3 Series is the geothermal equivalent of three different units—a
furnace, an air conditioner, and a boiler. This unique unit has the ability to do
forced air heating, forced air cooling, and hot water for radiant floors or other
applications.
Synergy3 products feature Scroll compressors and variable speed ECM
blower motors. During forced air heating or cooling, you may notice the fan
speed changing automatically depending on the mode of operation.
A sophisticated microprocessor control sequences all components during
operation for optimum performance with the ability to signal various fault con-
ditions (see page 16). The microprocessor also provides easy-to-use trouble-
shooting features and on-board diagnostics for your dealer to quickly identify
and resolve service issues. Safety features include high- and low-pressure
refrigerant controls to protect the compressor, freeze protection, and fan start
detection. In the unlikely event of a compressor failure, the emergency heat is
enabled to satisfy heating requirements. Another sensor detects if the con-
densate drain pan is full, at which time the unit will be shut down for protection
against water leaks (see page 18).
Depending on the application, you may have different thermostats to control
the different functions in various zones. One thermostat may be used to con-
trol forced air heating and cooling zones, with additional thermostats utilized
where radiant floor heating is used.
These units also have the ability to operate in a special “dehumidification” mode during cooling. In the event that the
desired temperature is reached before adequate dehumidification is achieved while cooling, you may benefit from
operating in this mode. Contact your dealer if you experience this condition.
Product durability features include heavy-gauge metal cabinets which are coated with durable poly paint for long
lasting protection. Synergy3 units include coated air coils for long life and cupronickel coaxial heat exchangers for
added corrosion resistance.
These units are performance-certified to ARI ISO 13256-1 standards, are ETL safety listed, and are
ENERGY STAR® qualified.
