Heating is nothing more than a series of switches. There's noting complicated about it at all.
I dont think NTC's Opentherm & ebus are simple switches? in fact not switches at all. A 40 year old S plan is just switches - but things have moved on - honest.
That's wierd because I wire up loads of heating systems for a local plumbing firm, and it's always just switches.
Room stat = switch
Frost stat = switch
cylinder stat = switch
limit stat = switch
programmer = switch(es)
thermocouple = switch
NTC = switch
zone valve = switch
Yeah there might be some fancy electronics in there but all it really boils down to is lots of switches
If you think an NTC is a switch then you know nothing about electronics.
Course it is. It gets to a certain preset temperature and something either starts or stops. That's a switch.
Nope not a switch and agree with Dan too a thermocouple isn't a switch either
it's a bit like saying a photocell is a switch

A photocell is a switch just like all those other things are.
When it gets dark outside does it just kind of magic the lights on or does it switch them on?
Just because someone isn't physically pressing a button, it is still switching when the external stimuli it is desingned to operate with reaches a certain value.
What about a relay? When power is applied to it's coil does it switch something on or off?
With a photocell when light levels drop below 70 lux it switches something on. It's the same theory with all the other devices.
Look lots of photocell switches
RF I have read enough of your posts in the past to know you are no dimwit
Methinks you are just being slightly argumentative as I was the other night
most temp sensors (heatmisor devices excluded) are made up of just one component namely these
you can argue the fact as much as you like but they are not switches (and you know it methinks )
If It helps I have just ate humble pie too above (well sort of)
