Why don't my Gas Central Heating Radiators turn on?

[justwannab]

Right then... my home has gas central heating/hot water provided by a Potterton Kingfisher MF gas boiler which is controlled by a Danfoss 103E5 electronic programmer (photo attached) which work very well together. In the hallway we have a (very dated) Honeywell room stat (photo attached) to regulate the temp, BUT, above that we have something called a 'Gent EMS6000 Series 6100 Economiser' (photo attached) which as baffled myself and others for some time now! The problem is that when the Danfoss programmer clicks to 'ON' either manually or via a preset programme, yes boiler kicks in and starts to heat hot water for the tank BUT the radiators will not kick in and heat up until the red illuminated 'OVERRIDE' switch is PRESSED to illuminate a green light which will then start the rads.


As you can probably understand this is a pain because when you get up on a cold morning or get in on a cold winters night from work even though the program has kicked in and boiler is running there id NO HEAT until you physically press the OVERRIDE switch on the 6100 Economiser. What is it actually for and how can I get round this problem so that the rads start automatically?


Can anybody HELP??? PLEASE!!!

must admit ive never seen one of those in nigh 40 years id be inclined to have it dissed as without instructions you will not have a clue how to use it

sounds like an old hot water priority system of which we installed loads at one time thats how it works

hi Stevetheplumber, thanks for your response. So my next question is what would you recommend for me to get the radiators coming on with the programme automatically and to have full control of either heating or water? Thanks again!
