Replacing a Drayton RTS for a Honeywell CMT927

[Lamaman1971]

Hi Folks,

We have recently moved into a house with a Combi Boiler and a hardwired Drayton RTS. Unfortunatly the RTS is not ideally placed and not representitive of the house in terms of temp (its in the utility). So, we would like to replace it with one of these wireless ones - the Honeywell one looks good. Anyway, currently the Drayton RTS has a Live, Neutral and a "Black" signal wire connected to #3 on the back box (see photo). But I "think" to use one of these Honeywell gadgets we may need to run in another core?

Im hoping not - hence the question to you guys.

Depends on the boiler make/model

Looks like it's configured for 240vac switching so

Thanks
