WARNING
To prevent electric shock, personal injury, or death, turn off the electric
power at the disconnect or main service panel prior to making any electrical
connections. Only trained and qualified HVAC professionals should install this
motor.
READ FIRST
smartphone and Azure ECM app (available from your app store or from the QR
code above) is required for the installation of this motor. This motor
replaces constant torque ECM’s (X13®, Endura® Pro, etc.), variable speed ECM’s
(16 pin), and many communicating variable speed ECM’s (4 pin). Due to the
complexity of variable speed technology the Azure motor should always be
connected to the factory harnesses and given a fan call to ensure
compatibility prior to fully installing the motor. If the motor does not
respond to a fan call, then the motor is not compatible with the equipment OR
the equipment control board is damaged and may require replacement. Upon
completion of Azure installation, confirm the airflow is correct. Always allow
the system to run for one complete cycle to ensure full communication and
correct operation.
Replacing 16 Pin Motors
(with harnesses containing more than 6 wires)
-
Turn off the thermostat and remove line voltage to the system; disconnect the two harnesses from the OEM motor and connect to the Azure motor. For constant
torque applications, connect the adapter to the Azure motor AND SET THE RED VOLTAGE JUMPER TO THE DESIRED VOLTAGE. Do not install the Azure motor; allow the motor to sit on the floor next to the cabinet to confirm compatibility. -
Apply line voltage to the system (thermostat off); open the Azure ECM app on your smart phone/tablet. The Azure ECM app is available for download by scanning the QR code above.
-
Select the sub-app Nos. 10856 & 10857; select Pair Motor and then select Connect.
-
Select Configuration and enter the application data (Image 1)
-
Apply line voltage to the system. Provide a Fan-G call (do not use Y or W). If the Azure motor responds within 2

Motor OEM – manufacturer of motor being replaced
-
Voltage – voltage of motor being replaced
-
Horsepower – horsepower of motor being replaced
-
Rotation – rotation of motor being replaced (as viewed from lead end)
-
Connector – connector style of motor being replaced
Select Next ; select Load Defaul t; select Save Configuration;
select Confirm; then remove line voltage for 1-2 minutes to save the
settings in the motor.
NOTE: FOR 4 PIN INSTALLATIONS YOU MUST ALSO ENTER THE MANUFACTURER’S NAME
OF THE EQUIPMENT PRIOR TO SAVING CONFIGURATION. minutes, remove line voltage
and install the motor into the blower housing. If the motor does not respond,
the motor may not be compatible OR the air handler control board is bad.
NEXT: PROCEED TO THE SECTION ON THE FOLLOWING PAGES FOR THE TYPE OF MOTOR BEING REPLACED.
- Re-apply line voltage, connect to the app, and advance through the Configuration screen to the Motor Output screen (Image 2) by selecting Next.
- The Motor Output screen displays the % of motor output for each operating mode. For example, 70% represents 70% of the maximum output of the motor at its rated horsepower. These values can be increased or decreased to optima.
IMPORTANT
TO CHANGE AIRFLOW WHILE SYSTEM IS IN OPERATION, ENTER A NEW VALUE AND THEN
SELECT TEST (BUTTON WILL CHANGE TO ON). THIS CAN BE DONE AS FREQUENTLY AS
DESIRED DURING TEST AND SETUP FOR FINE TUNING. TO SAVE THE SETTING, SELECT
SAVE CONFIGURATION AND THEN CONFIRM. REMOVE LINE VOLTAGE TO THE MOTOR FOR 2
MINUTES – ALL ADJUSTMENTS WILL BE SAVED. ALL CHANGES / ADJUSTMENTS REQUIRE
THIS PROCEDURE IN ORDER TO BE SAVED.
IMPORTANT
THE HVAC SYSTEM WILL CONTROL THE OPERATION OF THE MOTOR UNLESS ANY BUTTON
ON THIS SCREEN IS SELECTED. WHEN A BUTTON IS SELECTED, THE APP WILL TAKE
CONTROL OF THE MOTOR AND WILL NOT RELINQUISH CONTROL OF THE MOTOR OPERATION
UNTIL LINE VOLTAGE IS REMOVED FROM THE MOTOR FOR 2 MINUTES – THE SYSTEM WILL
THEN BE IN CONTROL OF THE MOTOR AGAIN AND READY FOR NORMAL OPERATION.
- Test system operation and check airflow. Adjust motor % output as necessary to achieve optimal airflow. If performing a temperature rise test, remove the call for heat and allow the motor to run to prevent excessive heat build-up in the heat exchanger after taking the measurements. This can be done by waiting 45 seconds before exiting the app. To exit, select Save Configuration and then select Confirm; remove line voltage for 2 minutes to save the settings. The motor will now be controlled by the HVAC system again. Test system operation.
Adding On/Off Delays:
The default settings provide no on/off delays. If delays are needed for the application
- Enter the Configuration screen, select Advanced Setup and select Next to enter Delay Profile screen (Image 3).
- Select Single-Stage or Dual-Stage. Enter desired values for On/Off Delay and % Reduction of Torque.
- Select Next. Select Save Configuration and then select Confirm. Remove line voltage for 2 minutes to save the settings. Test system operation.
IMPORTANT
THE % REDUCTION OF TORQUE REPRESENTS THE % REDUCTION OF THE MOTOR OUTPUT
VALUES OF Y AND W IN THE MOTOR OUTPUT SCREEN. FOR EXAMPLE, IF Y OPERATES AT
70% DURING THE CALL AND A 50% REDUCTION OF TORQUE IS ENTERED FOR THE DELAY,
THE MOTOR WILL OPERATE AT 35% DURING THE ON/OFF DELAY PERIOD.
Replacing 16 Pin Motors
(with harnesses containing 6 or fewer wires)
Re-apply line voltage, connect to the app, and advance through the
Configuration screen to the Motor Output screen (Image 4) by selecting Next.
The Motor Output screen displays the % of PWM motor output. For example, 80%
represents 80% of the maximum output of the motor at its rated horsepower.
This value can be increased or decreased to optimize airflow during system
setup.
IMPORTANT
THIS APPLICATION USES A PWM SIGNAL. USE THE PWM FIELD, ONLY; DISREGARD ALL
OTHER % FIELDS ON THIS SCREEN.
