Before Powering Unit, Check the Following:
NOTE: Remove and discard the compressor hold down
shipping bolt located at the front of the compressor
mounting bracket.
• High voltage is correct and matches nameplate.
• Fuses, breakers and wire size correct.
• Low voltage wiring complete.
• Piping completed and water system cleaned and flushed.
• Air is purged from closed loop system.
• Isolation valves are open, water control valves or loop
pumps wired.
• Condensate line open and correctly pitched.
• Transformer switched to 220V if applicable.
• Black/white and gray/white wires in unit control box
have been removed if auxiliary heat has been installed.
• Dip switches are set correctly.
• Hot water generator pump switch is “OFF” unless piping
is completed and air has been purged.
• Blower rotates freely.
• Blower speed is correct.
• Air filter/cleaner is clean and in position.
• Variable speed drive filter is clean and in place.
• Service/access panels are in place.
• Return air temperature is between 10-26.7°C heating and
15.6-35°C cooling.
• Check air coil cleanliness to ensure optimum
performance. Clean as needed according to maintenance
guidelines. To obtain maximum performance the air coil
should be cleaned before startup. A 10-percent solution
of dishwasher detergent and water is recommended for
both sides of coil, a thorough water rinse should follow.
Powering The Controls
Initial Configuration of the Unit
Before operating the unit, apply power and complete
the following Aurora Startup procedure for the controls
configuration. An AID Tool is required for setup, configuration,
and troubleshooting on the 7 Series Variable Speed system.
AID Tool version 2.01 or greater is preferred.
1. Configure Aurora Screen
a. Confirm AXB is added and communicating.
b. Confirm AOC is added and communicating.
c. Confirm MOC is added and communicating.
d. Confirm EEV2 is added and communicating.
e. Confirm IntelliZone2 is added and communicating
if installed. Set zoning system to OFF.
f. Confirm communicating thermostat is added
and communicating if IntelliZone2 is not installed.
Set thermostat mode to OFF.
NOTE: The AOC and MOC are the two boards that
comprise the VS drive.
2. Aurora Setup Screen
a. ECM Setup for Heating Airflow – select G, low,
high and aux blower speeds as appropriate for the
unit and electric heat.
b. Cooling Airflow % – sets the cooling airflow % from
heating airflow.
c. AXB Setup
i. DHW Enable – Ensure air is purged from
HW system before enabling (remember
the HW switch on the front cabinet)
ii. DHW Setpoint – 54.4°C is the default
but can be changed from 37.8 to 60°C
iii. 7 Series Variable Speed Pump Setup and
Modulating Water Valve Setup – Can be
setup to a range between 5% and 100%.
Defaults are 50% and 100%.
- From the Main Menu of the AID Tool go
to AXB Setup and select “Yes” at the
bottom of the screen to Make Changes
- Set VS Pump Control to MIN
- The pump(s) or water valve should
begin to operate and flow rate is visible
on this screen, it may take several
seconds for flow to stabilize. Adjust the
minimum % until the minimum flow rate
is achieved.
- Go back to Set VS Pump Control and
select MAX.
- The pump(s) or water valve should
begin to operate and flow rate is visible
on this screen, it may take several
seconds for flow to stabilize. Adjust the
maximum % until the maximum flow
rate is achieved.
- Press Enter.
d. Sensor Kit Setup
i. Brine Selection – for HE/HR
capacity calculation
ii. Flow Meter – activates the flow meter
iii. Select blower energy – PSC or
ECM/5-Speed ECM
iv. Activate energy option
v. Blower and Aux heat current
sensor activation
vi. Line Voltage calibration – Voltmeter
required to calibrate line voltage during
heating or cooling. Refer to Line Voltage
Calibration in this manual for more details.
e. Smart Grid Setup – Select action option for utility
received On Peak signal
f. Home Automation 1 and 2 Setup – Select type of
sensor for two home automation inputs.
