RWB

[solidair]

had an RWB2 controlling CH only which worked OK, but clock was bust. Swapped it for RWB29 which went straight onto backplate and seems to function properly - ie. lights come on when meant to! Trouble is the main burner doesn't come on when the demand for heat is there, just stays on pilot light. I can hear something else coming on (pump?), but no actual heat. Any tips?

Fault on the Boiler? what make and model is it?

Have you set the jumpers on back of clock to same as before

boiler seems ok - some sort of glowworm thingy. Have put old rwb2 back in & it worked OK again.

Then put new rwb29 back in & same thing happened - something makes a new noise as though the instruction is getting through, but main burner stays off. Room & boiler thermostat settings unchanged throughout.

Not sure what you mean about the jumper; am wearing a fleece myself as the heating's off!

You can carry on wearing it as im not telling you how to fix it now, hurt feelings

On back of clock is 5 little switches you prob need to change last one from pumped to gravity.

tried that but just the same.

Then removed it, switched off & started again - only this time remembered to push the reset as told in the manual.

Worked!! You star - thanks!!!
