Horstmann HRFS1 RF System

[The Rook]

My previous Drayton system has packed in and I'm looking to fit this horstmann system, to my combi boiler. There are three wiring systems. Can anyone confirm its the third one I want (page11 of the instructions) to attach into the external thermostat loop of the boiler? The previous drayton system is still attached, so I was going to use that for reference, but it's not that obvious.

The link to the instructions is :

Thanks in advance

Yes, that's the correct diagram (it's the same as the one on page 10!!)

Why a Horstmann - cost?? The Honeywell CM927 is much better and worth the extra money.

Pretty much cost, yes. Thanks for your help. If I have any problems though, I'll look that one up. Just as a query, how much would that system set me back?

They usually retail for over £100, but you can often pick up a brand new one on Ebay for about £70.
