burnham alpine red panel - I am suspicious that the difference between supply and return is greater that 90 degrees sometimes when the system was idle for a while. How can I avoid this condition? Thanks.

Red panel appears indicating too high difference between supply and return. Sometimes, after an hour, it recovers by itself. If I ask for heat from only one zone it recovers more rapidly.

See attached. Thanks.

It's nicely done. It's that a camera looking at the screen? Do you know what the settings are?

It is a Eufy pan camera (Amazon $45). See attached additional photos.

2 zones indoor heating. 1 zone hot water. Can you provide a little detail on why the setpoint may need to be lowered? Thanks again.

Error occurred before and after cleaning. Igniter changed, nothing really needed cleaning - gas high efficiency bioler.
