Compatibility between Worcester 30CDi & Honeywell Smartf

[ejhh]

I have

1) Worcester 30CDi system boiler

2) Honeywell Smartfit S-plan controller

Are the two compatible?


The boiler has a connection (jumper) between LiveSupply and LiveReturn at present (ie, no controller fitted). This jumper is to be replaced by the controller.

The Honeywell controller has 240v outputs for boiler and pump.

Since the pump is integral to the boiler system, persumably I can just ignore the Smartfit pump output and connect the Live Boiler output of the honeywell to the LiveReturn input of the boiler.

Can anyone give me a reason why this isn't a good idea?


btw- I have already discounted the use of the optional diverter valve for the boiler for a number of other reasons. Hence Bosch's own controllers can't be used.

many thanks in advance.

boiler has permenant live to it ,you wire up programmer seperate to give power to motorised valves through cylinder/room stat.. then the Ls Lr are wired to microswitches on motorised valve .This is for an S plan.

IF you go on to honeywell site wiring diagrams are on ther and use in conjunction with your worcester book

It's a bit odd, Honeywell don't give a wiring guide for the Smartfit system because they say it isn't necessary!
So there you have it, it must turn the boiler on with ripples through the ether.
