I live in Ely, so we me be on the same part of the grid. It is a bit of a joke round Cambridge. The programmer just locks up and has to be reset by switching off the mains supply. The display goes blank and the heating/water is switched on. You cannot do anything with the timer. Did it with both...

Just got the fiollowing reply regarding suppression. "I can send you a surge suppressor if you forward your postal address. It should be fitted between terminals L and N on the wall plate of the programmer." Hopefully that is the cure.

Found this by accident when doing some research last night. http://www.tfc-group.co.uk/_sa_webapp/runf579.html?page=310 There is a section about "Why does my digital programmer reset and sometimes freeze?". Sounds familiar and looking at the PDF below it it seems they sugeest fitting...

With me it only happens with rapid power fluctuations (spikes), it doesn't happen during a cut, I have tried to simulate it by flicking the switch on and off, but it is fine. I could switch it off with a hammer, could you enlighten me how to turn it on afterwards. :D

When I say stroppy I just pointed out that I had sent numerous emails and had not got a reply. I wasn't rude, just direct, in the manner that some other people normally correspond. When I got a reply I apologised for what I consider being stroppy and pointed out why. It obviously worked, unlike...

I am onto someone who seems very helpful, he is passing it to the design department and they will get back to me, hopefully later this week. Cheers Mike

Sent a slightly stroppy email and got this as a reply: If you have had a situation where the heating has remained on with the room thermostat set to minimum setting then either the room thermostat is defective or the motorised valve that the room thermostat is normally wired to is...

Thanks guys, I would never had guessed that you could replace them on the same backplate. I found this: http://www.energycontrols2.fsnet.co.uk/danfoss%20clocks.htm So I will probably go with the Siemens RWB9 - I can pick one up new cheaply.

Getting nowhere with Danfoss, they are not replying. Can anyone recommend something to replace this, I can do it myself, I am not an electrician, but I work with electronics, so hopeffully i can work it out. I just want a simple timer that does not do this Thanks Mike

I did also send them a link to this thread. I have also found other people on the web saying they are getting the problem.

I emailed them, but this is all the contact details from their website: Danfoss Randall Limited Bedford Ampthill Road MK42 9ER Bedfordshire United Kingdom WWW-Address: > www.danfoss-randall.co.uk E-mail Address: > [email protected] Timezone: GMT +0 Dial code: +44...

Thanks Guys, I have emailed Danfoss, if I get a reply I will post the reply. Regards Mike

We had a fault that caused this on our timer, also an FP715,and had to have a new timer because it wouldn't reset, we had the same model installed as it was just a quick swap. This does exactly the same thing, but only for like a power blip, not power loss. The problem is that when this happens...
