Swapping Drayton Digistat SCR with Salus Receiver

Hi there,

We've constantly had issues with our Drayton wireless receiver losing the signal from the stat. This time it's given up altogether, after googling this it appears to be a common fault with the Draytons.

I've therefore decided to go for the Salus RT500 as it seems extremely reasonable for the price and a friend has one with no issues at all.

My question is, is the receiver a fairly basic swap for the Drayton. Looking at the instructions the wiring seems similar but the connections have different names, although L and N I can cope with fine! But on the Drayton there is a COMMON (terminal 1) and CALL FOR HEAT (terminal 3), each has a wire in.

I currently have terminal 3 wired to 1 to fire the boiler due to lack of signal from the Digistat.

On the Salus there is a COM and an NO terminal (normally Open) should I therefore connect the common to COM and the wires from terminal 3 on the Drayton to the NO terminal on the Salus?

The Salus does not need an earth either so I will make these safe.

Thanks for your help!
