How to reduce Error 03 messages?

Postby rpav » Tue Nov 17, 2015 5:36 am

Hi folks,
after few days of OTGW running, I can noticed, that there are few Error 03 msgs. It is with QAA73 and Geminox THRi (LMU64). There are only few of them each day:

me@rpi:/usr/local/otmonitor# fgrep Err ot*
otlog-20151114.txt:07:07:04.954661 Error 03
otlog-20151114.txt:07:07:08.925833 Error 03
otlog-20151114.txt:07:07:33.818319 Error 03
otlog-20151114.txt:15:46:09.541185 Error 03
otlog-20151116.txt:19:24:47.015004 Error 03
otlog-20151117.txt:01:56:59.011081 Error 03

Is this something I sould worry about?
Is there something I would check to reduce Error 03 msgs?

Thank you for advice,

According to it's related to reference voltage.

I thought I had already answered this one. No, there is no need to worry about an occasional error message. The thermostat will re-request the failed DataID and continue.

The remark on the troubleshooting page about the voltage reference is for when you have communication issues due to excessive error 3's. That's clearly not applicable for you.
