Install Instructions

Product Description

The Azure

Hand Held Programmer allows the Azure

Digi-Motor

(MARS No. 10860/10861) to be custom speed

tuned to each application. Although the motor performs an auto sizing function that will correctly assign torque to

each of the speed taps for the installed application, there may be instances when custom speeds are desired.

• Allows blower speed to be reduced to the low end of CFM tolerance for improved dehumidification.

• Allows duplicate speeds to be set on multiple speed taps.

• Allows CFM to be maximized especially in high altitude applications.

• Provides speed tap flexibility for multi-stage systems.

Connections

These instructions assume the Azure

motor has already been properly installed, auto sized, and the necessary

speed taps have been connected.

1) Remove power to the HVAC system.

2) Plug the BROWN/WHITE harness on the programmer into the BROWN/WHITE harness on the Azure

motor.

3) Connect the RED power clip on the programmer to +24V (R on thermostat).

4) Connect the BLACK power clip on the programmer to 24V (C on thermostat).

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.

Operation

When powered and connected to an operational Azure

Digi-Motor

, the programmer will provide a digital display of

the % of max motor torque being applied by the speed tap that is energized on the motor. This figure is a direct

correlation to motor speed and serves as a point of reference when increasing/decreasing and setting motor speeds

on any of the taps.

1) Apply power to the system. If the blower is not running, the programmer will display ‘--‘. If the blower comes on,

the programmer will immediately display the % of torque on the energized tap.

NOTE: The programmer can only adjust one speed tap at a time. The speed tap must be energized. In order to

read and set the speeds, one of the following procedures should be followed to energize the speed taps:

Installation Instructions MARS No. 08502 ® Azure Hand Held Programmer (continued from front) a) The HVAC system can be run normally, that is in heat and/or cool mode. During the cooling cycle, the programmer can be used to adjust the cooling speed. During the heating cycle the programmer can be used to adjust the heating speed. Or b) The individual speed taps can be ‘forced on’ by directly connecting them one at a time to a +115V line connection (or a +24V connection for X-13 mode).
