Palmdancer Posted December 14, 2006 Share Posted December 14, 2006 Hope someone can help.We have a 1991 Saunier Duval Gas boiler for CH and water, but it has no timer or room thermostat fitted. I would like to fit a simple NO or NC type but I cannot find any connection block inside the boiler case to connect to. I was looking for a loop wire that might show the connection position but no luck.How do I fit a thermostat/timer? Any ideas?Rob Link to comment Share on other sites More sharing options...
Michael Posted December 14, 2006 Share Posted December 14, 2006 Palmdancer. Depending on make, model etc,behind the control thermo stat knob you will find the box ,take the cover off, on the wireing strip you will probably find a red link wire between{ SL and !!!} maybe 9, remove, you can fit the prog or time switch etc to this.Saunier Duval have a lot of boilers in there range. But on older types the blocks are pretty standard.Go on Sauniers web site, look under tech and manuals you can down load the guff on your boiler free.Michael Link to comment Share on other sites More sharing options...
