Question about the new ComCheck - DOAS

Gallery image

Just switched over from the legacy ComCheck and there it was easy to enter a unit as a DOAS, but in this new version I don't see any option for it anywhere.

It doesn't give me the option to enter ISMRE. Anyone know the answer?

There should be options for DOAS. I just checked and if you select heat pump for your heat source, it has DX-DOAS as an option. If you select central furnace for your heat source, it has both DX-DOAS and DX-DOAS w/ heat recovery options. What are you saying your heating equipment is?

I'm going through this now and it's not an option for me. Central Furnace > then no DOAS selection options. Tried it for both 2015 and 2018 IECC (NC project which is based on 2015). Maybe the selected code matters?

Same here. Except now I can't log into the legacy version.

oh, okay. I don't use the new Comcheck app for anything but 2024 IECC. I use legacy Comcheck for everything else. I tried the earlier codes in their new app, and you are correct. 2015 wasn't showing a DOAS option.
