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.

The Evolution Connex Control will light up and display the Brant logo

and then begin the commissioning process by displaying "Searching for

indoor unit".

NOTE: 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.

The Evolution Connex Control will then proceed to communicate with

the outdoor unit by displaying "Searching for outdoor unit". This
