All 3 in control box fuses OK. Tamper reset does not work, with either keypad. Pictures as requested. Thanks for your help.

Can I disable the tamper circuit?

Done as suggested. Tamper light stays ON. Intermittent tone all of the time. Unable to set alarm, just get two tone "beep"

Thanks for your input. I'll try that tomorrow just in case the alrm activates ! Going to need long arms to reach the keypad and control box at the same time - LOL

I did add some connectors on the 2nd attempt to avoid blowing fuses and to aid a quicker install.

Suddenly the hot water output on my Ravenheat 820/20 has stopped. When drawing hot water the main burners do not ignite. However if I turn up the room thermostat so that it turns on the central heating the main burners ignite and I can get plenty of hot water. The radiators are cold for as long...

Hi, I have a 10 yr old Ravenheat 820/20 and it has had this problem for a few years now. In the summer, when the Central heating is turned off, the hot water supply is fantastic. As soon as the colder weather approaches and the central heating is turned on the hot water supply temperature...

Hi everyone. Seems like a good forum. I have a 6 yr old Ravenheat 820/20 which has a strange problem. The central heating is fantastic (close loop) with scalding hot radiators. However my thermostatic shower is unreliable. In the summer, when the central heating is OFF its fantastic. Lots...
