Hello all,
Just got a quick question about what the temperature potentionometer dial controls on the Worcester Bosch 240 combi-boilers.
I have long been under the impression that it only controls the temp of the water coming out of the taps and as such I have always set the dial at 1 as the hot water temp coming out of our taps has always been toasty at this setting.
But the boiler regularly cuts out with the dial at this setting. By that I mean that the overheat thermostat regularly shuts the boiler down and I have to manually reset the switch to get the central heating working again. This normally happens after the heating has been on for a number of hours, the rads are good and hot and the house has already warmed up nicely. We also have thermostatic valves on all of the rads in the house.
Tonight, with just the central heating working, I changed the temp control dial from its lowest setting to its maximum setting and was able to get the boiler to alternatively shut-off (when at minimum) and fire-up again (when swinging the temp control to maximum) continually. There was no demand on the hot water when doing this, just the central heating was working and the boiler was simply responding to the changes in temp settings on the dial.
This would suggest to me that the temp setting dial also influences the way the central heating works and not just the domestic hot water. Am I right in thinking this way? If so, would setting this temp too low affect the overheat thermostat and cause it to kick-in more often than normal?
Cheers for any info.
