Ventilator; Utility Curtailment; Hydronic Airflow - Bryant Evolution Connex Control Installation Instructions Manual

6.3.9.4. Ventilator

When a ventilator is installed, the installer has the option of selecting the time interval for
cleaning the ventilator. After the selections are made, touch SAVE.
• Clean Interval: Selectable from 60, 90, 120, 150 or 180 days. Default = 90 days
NOTE: This option may NOT be available with the ERVXXNVA ventilator due to its
simplified control design.

6.3.10. Utility Curtailment

NOTE: Utility Curtailment and Utility Saver functions are different than the Utility Demand
Response function described in the Owner's Manual. Utility Curtailment/Utility Saver uses the
UTIL and Y2 (or equivalent) terminals on the Evolution System compressor section control
board to receive a dry contact relay signal from the Utility, typically from the electric meter
assembly, to signal a curtailment period. This section describes the actions taken in response to
that signal. See the equipment installation instructions for more information on wiring the
compressor section control board to the Utility connections.
Utility Saver is used to force the equipment to a lower stage (low or off) when activated by the
utility company, typically during peak load times. This setup is available only if the equipment
has a utility saver input (refer to outdoor equipment installation instructions). This setup
controls the response of the equipment when the utility saver input is active. DISABLED
means that the curtailment function is not active. TURN OFF means the outdoor unit is to be
turned off when the curtailment function is active. LOW STAGE means the outdoor unit will
run in lows stage when the curtailment function is active. After the selections are made, touch
SAVE.
