Is this how evohome works.
I expect someone will point me to a diagram which explains all this,but I haven't been able to find one,
I have probably got this totally wrong, so could someone tell me what acutally happens.
simplified..
assuming room temp is 15 degrees
current setting is 10 degrees.
I set room in phone app to 20 degrees for 30 minutes
app sets room on evohome controller to 20 degrees for 30 minutes.
evohome controller waits until HR92 next talks to it, and tells it to set room to 20 degrees.
HR92 compares wanted with actual temperature and if its higher opens the valve and tells the controller it wants heat.
controller tells boiler relay to switch on boiler.
after 30 minutes
controller waits for hr92 to next communicate, and then sets it back to 10 degrees.
hr92 closes valve and tells controller it no longer wants heat,
controller tells boiler relay to switch off boiler.
or does the controller handle all the temperature comparison etc as the above sequence wouldn't explain how open therm works.
so what actually happens, just wondering
thanks
