Anyone seen/used a Resol Deltasol B controller on a CH system?

[Marco]

Been to a rental house a few times now with various leaks and general poor plumbing. Its got an older system boiler, stnd timer and room stat. But also its got one of the above controllers. I did a quick Google and they seem to be used mainly with solar systems. I didnt notice any solar system when there, but wasn't looking on the roof for one either!! Will look next time here! Anyone think of what they would be used for if on a standard sytem boiler (not combi)?

I'm interested in general, but also anticipating they may call me with a heating/DHW problem, as been problems with nearly everything else, so wanted to see what people had seen of them.

Cheers...

Try the navitron website I think they use them they are basically temperature differential controllers.

Been back there again! Lo and behold...when I went to the bottom of the back garden and saw past the conservatory, there was a solar unit. The tenant didn't know anything about it!
