For easyness I am just going to replace the timer with an APT IMM24. The following wires are connected to the existing Flash Immermat terminals: 1 - Brown 2 - Blue 3 - Black 4 - Red The APT IMM24 has only 3 terminals, 3=Neutral, 2= Live (Supply in), 1=Live (Supply out) I...

Ericmark, just spoke to a plumber friend of mine and he said that a combined thermostat and timer wouldnt be a good idea as it will be in the front room which is probably the warmest room in the house as it is the most used and as the TV etc in there. He said that even though the rest of the...

Silly me, I must have misread as I thought it was mains powered :oops: What about this then which I think is main powered and seems similar to the one you suggested? http://www.horstmann.co.uk/downloads/ElectronicDocuments/ThermoStats/AS1Installationguide.pdf

After taking Ericmark's advice on board would this be better, as it is connected to the mains which is what I would want, and would it be suitable to replace the Flash Immermat? http://www.screwfix.com/p/danfoss-tp4000-24hr-programmable-room-thermostat/90659?_requestid=2373793

Ericmark thanks for all your help. I have not bought anything yet so am open to suggestions, I was only thinking about the Horstmann C17 as that is what a few retailers mentioned as a replacement when I was looking for the old timer. No doubt that is because it was what they stocked! A...

Thanks for that. The existing timer does the central heating and hot water. There are also no TRV's. Does this change things?

As requested the following wires are connected to the existing Flash Immermat terminals: 1 - Brown 2 - Blue 3 - Black 4 - Red Therefore if I was to use the Horstmann C17 what wires would go to where? Also if the C17 only requires 3 wires, as it says it does, what do I do with the 4th...

Thanks for that, yes the weather certainly is getting colder. By the fuse in the supply to the heating system, and this may be sound like a really daft question but I am just making sure, I presume you mean the fuse in the fuse box? If it is more do I just change it to a 3amp? When I get...

Thanks for your reply. The Immermat is used to control oil fired central heating. Would this timer then be suitable for this or should I look at an alternative? I will check on the wires when I get home.

I curently have a Flash Immermat timer as shown in the URL below: http://download.hager.com/controls.hager.com/files_download/Notices%20PDF/9419_527_01_GB.pdf I have previously replaced this myself, when it was faulty, with the exact same model so that it was easy to do myself. However I...
