Looks very clean, yes. Text in copper: i reduced it to almost zero after
getting the two-side component legend "silkscreen" done. you can put much
more
information on it.

Getting his 2 second oscillation results i think there is not much
tweaking needed.
Hysteresis won't make it better, and a rate component is IMO not helpful
for beginners.
also it must be a very big rate comp. (heating systems are very slow) and
i have
no experience with that, and no time to experiment just now.
The zero crossing detector of the opto "slots" the control input and
prevents too much
oscillations i think.
If a control loop guru is willing to provide assistance i will try
modifications.
