Setup for Evolution™ Control Furnace or
FE Fan Coil (Communicating)
This system can only be installed with Evolution™ -capable indoor and
Evolution™ Connex™ System Control using the latest software version.
When using an Evolution™ Connex™ System Control, airflow is
automatically selected based on equipment size. The user has the option
of selecting Comfort, Efficiency and Max airflow for Cooling modes.
These should be selected based on balance between the homeowner's
comfort and energy consumption
expectations. Efficiency airflow is used to meet specified AHRI
performance ratings.
See Evolution™ Connex™System Control Installation Instructions for
additional available adjustments.
Due to using a communicating control with the fan coil or the furnace,
dip switch adjustments are not necessary. The outdoor unit configuration
and the indoor airflows are determined by communicating control setup.
Verify that the PCM, VFD and Evolution™ System Control are using
the latest software before proceeding with the next steps.
Follow these steps to properly start up the system:
1. After system is evacuated, close the disconnects to energize indoor
unit, outdoor unit, and Evolution™ Connex™ System Control. Do
not attempt to operate the system in heating or cooling mode at this
time. Mode: OFF. Vapor and liquid line service valves should be
fully closed.
2. If the outdoor ambient temperature is between 65°F and 105°F and
the indoor temperature is between 65°F and 80°F then the system
may be charged using the subcooling method. At this time, fully
open the liquid and vapor service valves if the subcooling method is
to be used.
3. The Evolution™ Connex™ System Control will proceed through a
series of setup screens. Follow these setup screens to correctly
configure the indoor unit, lineset configuration, climate zone, and
outdoor unit coil material
configuration screen will take the user to the respective selection
screen for the line item
