my system
boiler potterton profile 100E Boiler stat 1-6 (6 being max) i have it on 4
Indirect cylinder
cylinder stat Honeywell L641A1039
Valve 3 port Honeywell V4073A1039
honeywell programmer ST6400c
This morning found HW very hot at the taps investigated and found that cylinder stat was not clicking further also switched HW demand and the stat would not cut off the boiler so i think the cylinder stat is knackered.
2.I still think the water is very hot with boiler stat @4 am i right that at 4 setting the water temp should be around 73degree? unfortunately donot have thermo to check water temp my question Is it possible for the 3 port valve to heat water when only ch is demanded ? If so how can i check this?
thanking in advance for all help/advise
