Under Floor Heating not working

[dexter9]

Are you sure? I thought the bottom one was because its also called a underfloor control system wired?

I'm learning a lot here. The unit you have describes is a floating action mixing controller. The unit I describe is the control system which receives all the signals from the thermostats. So am I right now that the one I described is the one you mean? I'm only trying to help as you are limited to know what systems have I Installed.

View attachment 12241This is the whole set up. All in all does anyone think its the brains cause I hear they're expensive?..

Looks like its a weather compensation unit in there you need to get in a good spark to see what's wrong
As said could be as simple as a fuse in slave manager

Hi. Fixed it myself. I took the cover of the unit I described and there seemed to be reset button and I just pressed that. Thanks for all your help.

Thats an esbe 3 way blending valve with the unit above being a weather compensator made by Tecmar in the US. I have found that once you need to reset the Tecmar unit they can have a very short lifesapn. Last time i checked (4-5 years ago) they do recondition them (if you can send it and be without).
Hope its all ok.
