Hi Guys

I'm having trouble chasing this up and think this is the home of old tech heads right ; }

I have to retrofit an old boiler / coils / fans ect with new controls, there is a Satchwell contoller that I will need to change to new, the old Satchwell model is as shown, see pics!

Does anyone know what I can change this with, any info would be greatly appreciated as Schnieder Australia has been no help.

Thanks Guys !!!!!!!!
