My furnace: Carrier 58MCB060. 1/3 HP motor.
I decided to put in the Mars Azure today, had the house to myself so I didn't need to worry about rushing through information technology. Got information technology installed, ran the car sizing and it it never stopped, I sat beside it for over 8 mins and it never spooled downward. I shut it off, went around making sure all the vents in the house were open (they were), adjusted the zone dampers to be more than equal and ran it once again. Let it run for a good v mins and gave upward. I read in this thread that chrisyng couldn't get sizing to work either and just used it as is... the troubleshooting steps from Azure too said yous tin can purchase the programmer to set it if information technology won't size so I decided to conduct on, I'll order the programmer afterward today.
Here'due south the play by play:
- auto size didn't work (information technology never stopped, tried twice) so I simply hooked up the speed taps and removed the learning harness (medium high - cool, medium - rut). I didn't employ the loftier tap because the piggy back tap didn't fit, I was going to change information technology when I got the programmer.
- taped upwards unused fan taps so they won't short
- Air conditioning was running for about 45 mins with the 18160 and the breaker tripped for the furnace
- checked wiring, looked ok. Reset breaker and simply the Air conditioning compressor runs, no error codes on the mainboard, no sound or motion from the Azure
- tried without the Azure surge protector, null happens (breaker doesn't blow either)
- checked voltage at the board and harness at the motor and there's juice (116v for the L1, 24v where it should be).
- I gave information technology one final try... I put it back into learning mode and goose egg... motor seems expressionless.
- removed the Azure and put back the original PSC motor.... everything has been fine for the past 3+ hoursAny advice? I purchased information technology from Discount Plumbing.
Oh yes, forgot the options I used for the config:
120v
counter clockwise
PSC
(quoting myself for reference )
Disbelieve Plumbing was astonishing, sent me a replacement unit of measurement within a week from when I first posted above. I didn't accept time to effort again and didn't want some other self inflicted AC outage. Finally got a cool mean solar day today and swapped in the new Azure motor. I didn't autosize it in fearfulness of bravado information technology up over again and just hooked it upwardly for regular operation (similar to @thriftshopper ). And then far, ii Air-conditioning cycles and no issues, have played with manual fan on/off on the ecobee and it's working as information technology should. Perhaps one day I'll revisit auto-sizing, but it works every bit is so I'thousand not touching information technology.

I've been running the air handler with the Mars Azure motor constantly at low-medium for the past few days due to fume (hopefully the electrostatic filter works, though some seem to indicate information technology does but not for long, or well, or both). Average power consumption for the calendar month prior (no a/c apply this year, other than a piffling bit to check that the HP is working) was 15.8 KWh. The past 2 days, power consumption has been 24.seven then it appears the motor is drawing 9 KWh per day. No baseline for what the old PSC motor drew.

Hey guys, newbie here to furnace DIY but I finally got around to installing the 10860 motor.
I mainly want to take advantage of the constant low speed mode, simply unfortunately I couldn't observe a fan connector on the motherboard, I did see a ACC power for the humidifier, will this one work for the constant low speed?
According to the transmission, without the fan connector, the simply choice would be to plug into a abiding line power, only the downside is the fan will be running all the time and tin't be controlled by the thermostat.
Thanks a lot.

Better diagram (and transmission) hither.

The good news is that there are two speed taps. Ane for heating and 1 for cooling. Bad news is, y'all probably don't want/tin can't become the desired combination.
What y'all should determine is if the HTB ACC and ACC taps are energized (120VAC) with the fan on simply no call for estrus, (and improve withal, not energized when fan is off). Y'all should exist able to connect the low speed tap there.

What you should determine is if the HTB ACC and ACC taps are energized (120VAC) with the fan on but no phone call for estrus, (and meliorate still, not energized when fan is off). You should be able to connect the low speed tap in that location.
HTB ACC is energized with 120v with phone call for rut
ACC is energized with 120v with call for fan, this doesnt help annihilation every bit the motor defaults to the highest speed energized. (call for fan without rut/cool demand energizes heating speed)
Only style to be able to control constant low speed from the thermostat is to install the constant low fan kit

I think your numbers are off, dont think the motor would cartoon that much ability
9kw/solar day is 375watts/hour, this is psc power consumption territory
I recall the motor is drawing closer to ii.5kw/day unless your ducts are severely restricted

Just surmising by using the daily power usage readings, which I do admit could be inaccurate.
Having a expect at the hourly item - the overnight usage with fan on - seems to point power consumption was 0.48 - 0.49 KWh for most nights and 0.55-0.57 KWh for one in detail. Perhaps it is the American Standard AccuClean that was burning power.
The nights earlier and afterward with the fan off had power consumption in the 0.xix - 0.24 KWh range (though 0.19 - 0.20 seems to exist more typical) and then it would appear consumption past the fan motor and air cleaner would exist anywhere from 240 - 360 Wh with 280 Wh (or 0.28 KWh) actualization to be a more than accurate number. The air cleaner only requires 24VAC and then it tin can't exist consuming that much?
Unfortunately, I do not remember a time when I had the OEM PSC motor running overnight w/o rut to go a comparable consumption.
The air is pushed into a 12" round duct and feeds 4 - 5" ducts (lengths can vary from very brusk to long and down). Registers are all fully open up merely I did restrict/close off two vents that rut the clamber space. I did record upwardly the joints with aluminium tape so this has minimized leakage. Maybe I should open the closed up vents to recoup.
Do note that the motor has not been calibrated. The get-go ane burnt up after calibration, and another user reports his motor also burning up during calibration. Both of united states had Carrier air handlers/furnaces and are a little shy of trying to calibrate again.
I exercise seem to retrieve you saying in a prior post that the motor may not produce any savings?

How are you reading the ability draw. Perhaps you're reading VA vs Actual wattage. ECM have lower power factors

You lot only take a single 12" round with (4) v" runs off your furnace?? Thats as well restrictive even for the smallest units...
The college the static pressure, the more torque information technology puts put, and cfm per watt goes up. Not linear. At the top cease, the amps is probably not that far less than a psc motor.
You will relieve a bit if yous run low speed fan 24/seven merely it is also likely moving less cfm than the psc....
Calibration is just a gimmick, its just guessing what to program the speeds to run at by looking at torque/rpm. It has no thought what cfm its suppose to be running at.
Better off setting the correct speeds yourself.

Oestrus pump. FWIW, information technology goes off in both directions (think of the 12" round running the length of the house with the handler in the middle.
The higher the static pressure, the more torque it puts put, and cfm per watt goes upward. Not linear. At the top end, the amps is probably not that far less than a psc motor.
You lot volition save a bit if you run low speed fan 24/vii only it is too probable moving less cfm than the psc....
Scale is just a gimmick, its merely guessing what to programme the speeds to run at by looking at torque/rpm. It has no thought what cfm its suppose to exist running at.
Better off setting the correct speeds yourself.
Medium speed seemed too high (noisy) so I am using depression-medium. I recollect low is too depression.

Sorry, to clarify, a 12" round that goes ~thirty' in either direction (straight line) from the HP air handler. 26 4 and v"
ducts off that. Nearly are 5" simply there are a few 4" ones for whatever reason.
