I got a SIME based 80C format boiler which has Clock type timing system. Internal clock display time from 12 3 6 9 and outer clock in 24hr time scale. Could someone help me to setup the timing for room heating? Its confusing.. I simple need help to understand sync between internal and outer clock on same circle panel switch.Its like if you number internal dial in clock as 1-12 and outer dial as 1-24hr. Any suggestion is highly appreciated. Thank you.

Hi
I'm looking for the same thing but for a 80E sime, i don't know if they have the same switch but this is what i found :
The clock in the middle is for the time, the teeth around the outer edge is for the duration of the heating, if theres a three way switch in the middle then one way is off, the other is one and the middle is for the clock setting. Sorry, to be honest i'm still a little lost but maybe that might help you
