5.5" Azure Digi-Motor (1/5 - 1/2 HP, 115/230V, 1075 RPM)

Our air conditioner broke down in the middle of a heat wave the week our son was to be born. Really didn't want to bring him home to a sweltering house. The Azure Digi-Motor from Supply House was the best price and quickest shipping and arrived the day he was born, was easily installed by a knowledgeable relative and is working perfectly. Thanks Supply House for you assistance and quick shipping!

This is a very flexible motor for 120/240VAC applications, both CW and CCW operation, and works for both PSC and X-13 (24VAC signal) applications. I replaced a 1/2 HP Broadocean motor on a Carrier furnace. It had two failted speed taps and I am sure was just a matter of time before additional speed failures in the ECM circuitry. The Carrier version of the Broadocean motor was an X-13, but it has proprietary connections. With this motor, I had to splice on the connections but not a huge deal. A factory harness on other X-13 furnaces and air handlers will likely "plug and play." After making the initial connections as described in the manual, it did the "auto sizing" process as the motor self-measured the static pressure of my system. After that, I was able to connect the speed taps on the control board of the furnace. All of the calls are working, and I am very happy at saving hundreds of dollars over the OEM motor.

Worked great as an upgrade from the PSC motor in a Miller downflow furnace. Took a bit of fiddling to get it to work well with more than one fan speed but that is just bc of the way that furnace is designed. I like the quieter slower constant fan tap which was the main reason for the upgrade. Grab the packard mount also it worked well and didn't block any vent holes

I've installed and tested this unit for several weeks now. I plan to buy a second unit in the near future. Prior to replacing a PSC motor with this product, I installed an amp meter with a cumulative KWH display and here's the take away: the Digi-motor will cut power usage, in my case not quite 1/2. The caveat is that if you are replacing a 1/8hp motor, it may be more cost effective to buy an aftermarket motor. I chose this motor to replace the blower motor on a 21 year old Trane, 2T air-handler since it is in the second story of my residence and is used the most year round, especially in the summer. Prior to replacing the old, three-speed, 230V, 2A, 1/8HP, 850 RPM, sleeve-bearing motor, I ran Manual D and J calculations, took ESP readings, and amp readings. I then corrected defects in the system, both in the supply and return side. When the system was optimized per Manual D/J recommendations, I monitored the motor and saw a running load of 1.8 Amp (low speed-tap, manufacturers recommended speed for coil and CFM based on system ESP readings). I cleaned the blower wheel and installed the Azure Digi-motor. I performed the self-programming twice, as there seemed to be an issue after completing the self-programming in that speed-tap-two was moving an insane amount of air, such that the ESP reading were doubled and the amp draw was 3.6A for the motor. I used speed-tap 1 to limp by at 625 CFM (.5 A draw) and verified the output of the heat coil was not an issue (126 degree F observed) and sourced a programmer for the motor on flea-bay. With the programmer I was able to program speed-tap-2 to the desired CFM/RPM and am seeing a fan load of 1.01A. Speed-tap-1 is fixed and cannot be changed - it's intent is recirculate only and it is super quiet! Thus far, the biggest reduction in power consumption is the in-rush current at start-up: the old PSC motor peaked at 365W during start-up (running was 275W), while the Azure peaks at 118W (no startup surge).

I took a chance that the Packard model A60048 5.5" Blower Motor Mounting Bracket (3 Legs) had a 10" bolt circle (since it did not specify), AND IT DID – Just perfect for my Trane XR95 Furnace blower housing. Mounting and installing the motor went well. I wired the motor per the instructions in the 2019 Azure Digi-Motor Installation Guide for PSC motor replacement. I started the learning mode as specified. After a two-minute run, the motor was supposed to come to a stop for 30 seconds. However, it never came to a full stop. It slowed down, and just as I thought it should stop, it began ramping up in speed again. I did this three times with the same result. On the third time, I removed power just at its low point of speed, but it was still turning. I took a chance that it had programmed properly, and reconfigured all the wires to their final configuration: I unplugged the 24V programming wires and removed them and plugged speed wires to their proper location. It appears that the programming was successful. The HEAT and COOL speeds now draw less current than the original PSC motor did. I have one suggestion for MARS. When the motor didn't stop as expected, the procedure refers you to the Troubleshooting section where it states: "Load may be to great for the motor; try setting speeds with hand held programmer or try 1 HP Azure® (10861)". At this point in the installation, neither of these suggestions seemed reasonable. MARS should state what one could expect if they want to leave this motor in place like I did.

The installation instructions were very clear and easy to follow. However, there was one place where the actual experience differed from the expected experience described. After running the motor the first time, it is supposed to come to a full stop before you disconnect power from it. The instructions even say you have 30 seconds. My experience was that the motor NEVER stopped turning. It would slow down as expected, but just before it stopped, it would start up again. This happened several times, so I repeated the procedure several times with the same result. So, ultimately, I just disconnected power when it reached its slowest speed and luckily everything worked OK. Mars needs to clarify the instructions for the case where this happens.

Easy ro install and program

I used to make a multiple speed fan on my heat pump . Didn't need to add any relays . Easy install. Follow directions. I used mine as x13 set up to modify a psc set up motor . It's been 2 weeks so far very good

Perfect replacement for o.e motor, it is completely adjustable with the handheld programmer.

Simple to utilize!
