hot water/radiator problem.

na thats me yer fool

Reading down I'd come to much the same conclusion. Sounds like the valve is ar*e about face. Could be intentional, but not likely. Makes you wonder what else could be wrong with the controls.

 

[mickyg]

but as an after thought which port is connected to the cylinder ?

what he said. B should be connected to cylinder.

 

[dekesta]

B is connected to the cylinder. what should the set up be?? where should the pump be?? And why would it make a difference, surely there should be voltage for the valve when the ch is turned on wherever the pump is?????

 

[seco services]

ch on should have 230v on the

white from room stat.
grey from cyl stat satisfied/programmer hw off.
orange to pump/boiler.

 

[dekesta]

Thanks for that, thats really impressive, however I think I have made a monumental error, I don't even know where the room stat is, so now I presume it is set to very low. When I get back later i will check and get back to you all, but thanks for everything so far.

maybe they took it with them.

hanks for that, thats really impressive, however I think I have made a monumental error, I don't even know where the room stat is, so now I presume it is set to very low.

and bett wonders why i drink

aaaaargggghhhhhh

I wasa just about to suggest the room stat but see you have realised that it may need turning up !

Or it could be faulty. They are very reliable though.

still don't tell us why the motor has power on hw but not heating.

 

[dekesta]

oh really, i thought the stat would cut the power to the mech valve first. I will have a good look and check . Thanks

 

[seco services]

when hw is called for it shouldn't give power to the motor.
only when heating is called for.

hw has nothing to do with the mot valve.
only when hw satisfied or off live will be on the grey to the valve.

 

[kevplumb]

has nothing to do with the mot valve only giving live to the grey when satisfied.

you wanna rephrase that

 

[dekesta]

Thanks for everything guys, I have learnt a lot over the last couple of days, most importantly - start with the basics. It turns out that it was the wall stat that was set too low.
