Temperature Control-CENTRAL HEATING

[gnvqsos]

Our Worcester 280 RSF has a temperature control knob which used to click and activate the heating.I do not seem to be able to control the heating as before.I have read the fault-finder and I suspect I need a new potentiometer.I have bought one in readiness.It has a spindle one end and has three wires which attach to the PCB.

Can anyone confirm if I have the right part.Someone else has suggested that the current spindle may be faulty.

At the moment I am running the boiler all night (on a low setting) for fear of losing the heating in this cold spell

Ignoring the problem with your boiler control for the moment, I get the impression that the boiler temperature control is the only control you have over the house temperature? Or do you have a thermostat on the wall as well?

Thanks for your reply Hailsham.You are right-we have no renmote controls.Heat is switched on with a roller switch and temperature is controlled manually.I hope this extra information clarifies the situation

Thought so! You really should get some controls fitted to your boiler. It will save you money on gas.

What part number is the replacement thermostat you bought?

IT is a genuine Bosch part-no.386 227(GC) and is a harness potetiometer.I also bought a spare thermistor(379 785) at the same time.These spares could be scarce and a relative has the same model so it may come in handy.

We do not have controls and have low gas consumption.We all wear jumpers indoors and only put boiler on is adverse weather.If we feel cold the boiler goes on and is switched off when we are warm.thanks for your reply and for your helpful advice.Let me know if our spartan regime is wasteful

That's the correct part no for the potentiometer. The Installation instructions are Here

It certainly won't be wasteful and if you are happy wearing jumpers, I won't stop you! Controls just make it a bit easier. You could install them and set the temperature low, so the boiler only comes on when you feel cold. If that's 15°C - fine.
