To set the temperature and by pass the program feature press "HOLD" This feature is alternate action each time you press it changes from on or off, off to on.


This will make your 3M-22 act like a non-progammable thermostat. It will hold the target temperature you set indefinitely, until you turn HOLD off. Take care using the HOLD function as the program is now bypassed. To set a hold target temperature, press HOLD and use the +/- buttons to select your hold temperature. The HOLD icon will display on the HOME screen indicating you have changed the Target Temperature. The system will HOLD this temperature until you return to the manual screen. To turn off hold press HOLD again. HOLD is also canceled when you set the mode to OFF.

These things are like the old VHS tapes to program.

Hope this has helped?

What is the question that you have about this? What is the make and model of the hvac unit that it is running?

Hi smargyle,

Welcome to fixya!

I can provide you with diagrams for the old Carrier therm and for the new Filtrete therm. But, I would need to know what the model numbers are for each therm plus how many speeds AC you have.

Please reply back with that information and we will get your AC back in working order.

Thanks,

Take a look at these sites:

Well I found this page http://www.yourspares.co.uk/proddetail.asp?prod=1688461 and you can get the filter there for £22.25 , which is about $35.00. I simply took the part number EL7351031200 and searched for it. That's the cheapest one I could find though. I read that it's a 3M filtrete filter, and, knowing me, I would just buy a cheaper, larger filtrete filter at wal-mart, cut it to size, and glue it to the plastic frame of the old one. I hope you also know that you can wash the filter in warm water until it wears out.

I am also experiencing this problem, as well as 2 other people that I found on google, so I am inclined to think tha 3M has changed something in their manufacturing process, I think it very odd that this problem is manifesting itself at this time in different locations.
I have been using this product for sometime, and the problem of filters turning very dark did not exist when I started using this product
