My old Honeywell EMM-3U control board "went out" according to the HVAC company. Was quoted $500 to replace the board because it was a new board and required "extensive programming". He wouldnt tell us what board he was replacing our old one with, because I'm sure he knew we would call him out on it. We had a cold front coming in and were supposed to get extremely cold over the weekend so I ordered this with expedited shipping.
First the package arrived early and perfectly packaged. Pulled everything out and all was clearly labeled.
I have to say I am in the electrician field so wiring this for me was a breeze and definitely not worth paying someone else to do. As long as you know how many thermostats you have and can match your dampers to your thermostat, this is extremely easy.
Very nice to have the push in connectors, as the old unit had screws and I had to search and search for one to fit.
The push connectors makes the transfer from one panel to the other a breeze. If room permits I recommend doing one set at a time, i.e. equipment, thermostat 1, damper 1, thermostat 2, damper 2, transformer and then power.
I already had the transformer from the previous panel and saw no need to change it, same with the DATS. I did read depending on the sensor you have installed it may or may not be compatible so you might have to change this out, seemed simple enough to change though. ******Programming*******
I watched the install video prior to doing this and got a few pointers which I was doing just to be safe. Pictures are important for install, but in the video it specifically said that they weren't going to go over the programming because it was simple. So with that I pulled out the manual that came with the board and used it. VERY SIMPLE PROGRAMMING, stupid easy. All together the swap took about 20 minutes.
***Cons**
**Had one hiccup when I installed the cover back on I accidentally pulled one of the power wires out and the system never kicked back on.
Just make sure that your connections on the board are solid before putting the cover back on**
Does not come with zip ties to keep my OCD in check
Overall I am very pleased with this and I have found that i have a bad damper by going through the checkout that this panel has. Would highly recommend anyone this product and tell them not to be afraid to change it themselves. Take pictures of old board and roll with it,
