unit suddenly flipped outdoor and room temperatures #262

Closed rplevka closed 3 months ago

Describe the bug I use Itho ECO 350 unit with no external temperature sensors and the CVE Add-on I noticed that the unit started reporting exhaust temp as the outdoor temp (and supply temp as room temp) suddenly and has been reported this way since then. This happened 2 months ago and I only noticed now, after investigating, why the bypass has not kicked in. Unfortunately, I can't remember the version I have used by that time (2.7.0 or above) but I only upgraded to 2.8.0 recently (few days ago). image

I realize this might have nothing to do with the addon, but I am clueless so wanted to know, if anybody might remember some change that might have interfered with this.

I use manual mode sporadically but just to set the bypass valve to its position. @arjenhiemstra If you happen to have the service tool with the default settings for the unit handy, I'd appreciate If you found some time and shared them with me, so I could double-check the settings are the same.

Thanks!

update: so this is a false alarm. I have never realized this, but the unit seems to flip this together with the "bypass position" flag, whenever it is set to 1, the temperature mappings are flipped. after the bypass flag is reset to 0, they are flipped back. image

sorry for the fuss.
