4.7. Ventilator Connections
A 120VAC ERV (Energy Recovery Ventilator) or HRV (Heat Recovery
Ventilation) may be installed with a translator board (SYSTXXXTRB01)
and either a NIM or a Zone board. It maintains a consistent indoor
temperature and circulating fresh air throughout your home. The BGRY
wires are connected to the respective BGRY of the zone board.
4.7.1. Energy / Heat Recovery Ventilators
Both ERV (Energy Recovery Ventilators) and HRV (Heat Recovery
Ventilators) provide fresh air into the home and exhaust stale air. For
more information on the differences between ventilators, consult
ventilator pre-sale literature.
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
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,
