Micro-air Soft Start

[bikerider4818]

For those that have a Micro-air soft start....
I installed my Micro-air soft start ony 3 ton Carrier a/c unit, completed the 5 learning starts and the a/c is running perfectly and the amps went from 70 down to 25. The only thing I have a question about is....is the soft start supposed to only have power to it when the a/c compressor is turned on? Right now when the compressor is not running, the lights on the soft start are off and I can't connect to it via the phone app. When the thermostat calls for cooling and starts the compressor then I can connect via the app and see all of the data. Does this sound correct?

Yes, it only has power when the air conditioner is running. I have it on my 5 ton and that’s exactly how it functions and I think there is a YouTube video that also states that.

The soft start is powered by the contactor when the demand is there. I went from 109amps to 39 amps on a 5T unit. Lights no longer dim in the house. Very happy with it.

Yes. It's working perfectly.

Same behavior here, my 2019 5-ton TRANE inrush went down from 162amps to 33amps. When the unit is not running, the soft start has no power and no bluetooth connect is possible.

Yep that is how they work. I don't know why they didn't independently power the control circuit from the 240 volt none switched side of the contactor but oh well

I just installed one on my 3 ton Trane and it worked the same way. It is a little weird.

I self installed an ICM Brand soft start on my home a/c condenser and it also works great. 3 ton unit and it dropped the startup amps from 62 to 24 amps

Here is an example of it learning 1st time and after 5 times

Crossposting my two HVAC EasyStarts from last week.

Can my generator run my home aircon (heat pump)?

TLDR: Will my 7000W (10,500 surge) generator run my 3 ton heat pump? I have a 7000W genset with a NEMA L-14-30 connector. This is what the manual says "This receptacle powers 120/240 Volt AC, 60 Hz, single phase loads requiring up to 7,000 watts of power (7.0 kW) at 29.1 Amps for 240 Volts...

Follow up question. I have a two stage compressor/air conditioner. When I do the learn process, should I be lowering the thermostat down just enough to trigger stage one or lower it several degrees so that it kicks on the second stage?
