Wiring of Salus RT510RF thermostat to Vokera Compact HE29

Gudoldtom · Jan 7, 2018

Hi Guys I have an old room stat which is located upstairs in the hallway that I wanted to replace with the Salus RT510RF so I can take it from room to room. I was hoping to just swap it over but I think I will need to run additional cables, if that's the case I might as well just run a standard room stat from the living room to the boiler in the kitchen which is only 2m away. Any comments, recommendations, advise etc would be greatly appreciated as the wiring in the boiler is throwing me a little. Many thanks

Here is the wiring inside the boiler

Make those cables safe, they will probably have 230v accross them. Then wire in the Salus at the boiler, or airing cupboard using 5 core flex as shown in this diagram;

The Salus is a clock also isnt it, so I would remove cable 1 and 3 from the larger chock block and connect the salus into these

Hi thanks the cables are safe. I isolated the supply & removed them from the enclosure just for the post.

Hi Madocks should I just bypass the timer on the boiler altogether by removing all the cables from the chock & wire COM & ON directly to the chock?

May be call Salus support tomorrow?

I would, let the salus have full control, only concern I have is the little M in the diagram. Not sure what it is, looks like just a feed to the clock but could it be a motor of some sort perhaps? theres only a L&N going to it, but does the internal clock control some motor? label the wires up and fit the salus and see if it works
