5. Commissioning
This section addresses initial power up (or commissioning) of a new
Evolution Connex Control. The control will communicate and identify
all components in the Evolution Connex. The following is a typical
example for a communicating variable-speed furnace / fan coil with a
2-stage air-conditioner / heat pump (including HYBRID HEAT® dual
fuel system). The process may vary for other types of systems. See the
Evolution System HVAC equipment Installation Instructions for more
details, as provided.
5.1. Searching for Indoor Unit

If the Evolution System-compatible indoor equipment (package
unit indoor section, gas furnace or fan coil) cannot be found, the control
will display “Indoor unit not found”. This
MUST
be corrected before the
initial power up sequence can continue, proceeding to the next section,
“Searching for outdoor unit.” If it is not corrected, the Evolution Connex
Control will go into its DEMO operating mode. If a control is operating
in Demo mode and you wish to install it with equipment, navigate to the
Installer menu and perform a re-install to re-learn the equipment.
TIP:
Troubleshoot ABCD communication bus problems by removing all
but the indoor unit and system control from the ABCD bus circuit. As
each bus segment is verified, connect the next component and continue to
troubleshoot as required.
5.2. Searching for Outdoor Unit
The Evolution Connex Control will then proceed to communicate with
the outdoor unit by displaying “Searching for outdoor unit”. This
