Performance audit testing a (-)A18AZ/(-)P18AZ
variable speed heat pump rated combination requires
an EcoNet™ Control Center (according to the AHRI
rating database) as an accessory to obtain the rated
performance. Utilize the following instructions to
properly operate the system during audit tests.
1. Install the rated system consistent with this manual
and ASHRAE 37.
2. Leak check and charge the rated system per the
instructions found in this manual.
3. Wire the outdoor unit, indoor air mover/furnace,
indoor coil EXV control (when necessary), and
EcoNet™ Control Center according to the following
wiring diagrams.

pressing the orange up or blue down arrows at
the bottom of the screen twice.
f. Select “Off” next to the “Aux Input #1 Config”
label.
g. Change the “Aux #1 Config” value from “Off” to
“Shutdown” by pressing the orange up button at
the bottom of the screen two times. After each
press of the orange up button the value next to
the “Aux #1 Config” label should change.
7. Entering the Test Mode
a. Press the back arrow in the bottom left of the
screen 3 times to return to the home screen
showing the inside temperature.
b. Press the “Service” button on the home screen.

Test” label and then the orange up arrow or
blue down arrow at the bottom of the “installer
checkout” screen.
NOTE: Any faults must be resolved before the
