Hi everyone just like to offer the following information to anyone who may be interested
I work in Manchester on Gledhills alot!
Having replaced quite a few Omrons with the Scheider upgrade kits, Got to thinking why not upgrade the pulsacoil M111 Finder relays so I have with a 20amp twin pole a1 and a2 Contactor, costs less then half price, and it’s working well.
We are a Tradesmen family electricians and myself Plumber heating, I never normally fit anything but speck? This Contactor is built with a cut out, and is being monitored, by a good mate of mine who is an electrician in his apartment? and so far is working nice, no overheat problems.
If you would like to know more, would be happy to post more info.
Thanks James

Hi Mike
Sorry I don't post much, by the time I get on here you guys have answered everything, and pretty knowledgeable too.
The contactor I used is a 20 AMP FINDER RELAY - 22.23.8.230.4000 230VAC still going strong, for less then half the price.
I would say to people who worry about these relay/contactors blowing they are fire proof and are designed to melt, to lesson the risk of a fire don’t hang clothes, bedding old stuff paper!! On the boiler.
Any one working on Electramates 2000’s have a couple of mop buckets and some smaller container on the ready, if you are changing the heater bottle 9kw or 11kw change the seals for graphite fibre if you have them, be aware of the Ball O fix valve (XG160 the problem seems to show it self when you re-pressurise this valves lets go, I mean water everywhere, if you get water in the pump you’ve got a problem, to stop this from happening I carry clear plastic bags the size of a grundfos pump rap them around the pump then tape up the bags to the 22mm pipework because the bags are clear you will see if water is getting in, I promise it won’t!
Repressurise check for leaks takes the bags off, if water gets in, new pump new board.
Got A question like to ask you Mike.
