Hi, having a issue with this unit. It's not running. I've checked the controller and there is a demand for it to run but it does nothing. I've put the unit in test run from the outdoor unit and the controller says it's in test but nothing.

S1 and s2 is 230v s2 and s3 is fluctuating from 2v -22v. There are not faults, I have changed the outdoor board but nothing.

Tried calling MHI and left voicemails but they don't respond. Anyone have a number they answer?

I have noticed when 2 units in the one controller there can be up to a hour delay but I have waited over.

Cheers

You can still get technical from amp, s1 and s2 230v this your live and natural? I see S3 being transmission line and that fluctuating voltage is right but s2 voltage????

All s1,2,3 voltages are correct.

If you are expecting that someone will read your mind in order to get model number, you will probably wait few more decades until quantum mind reading is invented!;)
