The Synergy3 Series is the geothermal equivalent of three different units—a fur-
nace, 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 fl oors or other applica-
tions.
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 opera-
tion for optimum performance with the ability to signal various fault conditions
(see page 33). The microprocessor also provides easy-to-use troubleshooting
features and on-board diagnostics for your dealer to quickly identify and resolve
service issues. Safety features include high- and low-pressure refrigerant con-
trols 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 condensate drain pan is full,
at which time the unit will be shut down for protection against water leaks (see
page 33).
Depending on the application, you may have different thermostats to control
the different functions in various zones. One thermostat may be used to control
forced air heating and cooling zones, with additional thermostats utilized where
radiant fl oor heating is used.
These units also have the ability to operate in a special “dehumidifi cation” mode during cooling. In the event that the
desired temperature is reached before adequate dehumidifi cation is achieved while cooling, you may benefi t 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-certifi ed to ARI ISO 13256-1 standards, and are ETL safety listed.
