The Aurora ‘Advanced’ Control System cont.
AFFINITY & AFFINITY ADVANCED SINGLE & DUAL CAPACITY SERIES INSTALLATION MANUAL
Special Modes and Applications
5-Speed ECM Blower Motor
Normally the 5-Speed ECM motor can be driven off of thermostat
signals and the ABC connector P9. Communicating thermostats,
however present a special problem in this application since they
operate without 24 VAC thermostat signals. The ABC board is
wired to operate these systems from the alternate relay output
signals CC1, CC2, Fan, and EH1 and should be wired for this.
Communicating Digital Thermostats
The Aurora controls system also features either mono-chromatic or
color touch screen graphic display thermostats for user interface.
These displays not only feature easy to use graphical interface
but display alerts and faults in plain English. Many of the features
discussed here may not be applicable without these thermostats.
Dehumidification – Passive
In passive dehumidification mode, the airflow is reduced by 15%
from the heating airflow setting. If cooling airflow is set to +5, -5
or -10% of heating airflow it will automatically be set to -15% of
heating airflow whenever the dehumidification call is present in the
communicating stat or from the thermostat input DH. If the airflow
for cooling is already set to -15% no airflow change will be noticed
from normal cooling. Dehumidification mode will be shown on the
ABC and the communicating thermostats.
Aurora ‘Advanced’ Control LED Displays
These three LEDs display the status, configuration, and fault
codes for the control. These can also be read in plain English via
the Aurora AID Tool.

NOTES:
*All codes >11 use long flash for tens digit and short flash for the ones digit. 20, 30, 40, 50 etc. are skipped!
Alert’ is a noncritical sensor or function that has failed. Normal operation of the heat pump is maintained but service is desired at some point.
