[QUOTE="NozSpark, post: 495455, member: 601"] I have been asked to price a “non standard” boiler installation It will have 3 x 30kW heat only boilers 4 x circulation pumps 1 x automatic filling loop 1 x single channel programmer It will not have a thermostat The boilers are going to be Ideal Logic + and they require a supply and demand signal.... Ive just talked to Ideal and all that they will say (loading wise) is that each boiler will have to be treated as a separate installation The programmer has a 3A switching capacity —————————— I don’t know if I’m overthinking this (i have a tendency to!) or not, but I’m starting to think that the programmer will have to switch the boiler demand signal through a contractor (or two), which will also need to switch the pumps ..... the auto fill will need a permanent supply So.... I’m now thinking that I’ll need a panel making up with a DP switch for each boiler, pump and the auto fill.... then fused and a neon each (to show supply)..... and obviously a main switch and fuse for the programmer Does this sound right?????????? Or am I indeed over complicating matters [/QUOTE]
