Hi there chaps. Not posted here for a while.

I'm installing a underfloor heating kit in my ensuite. I've done all the wiring under the tiles, etc. I'm at the stage where I'm connecting the thermostat to the mains and sensor etc.

HOWEVER, I'd not looked at the thermostat block that closely before. And its occured to me, I have no idea how it fits into the knockout box. See the attached image for what I mean.

Does anyone know what sort of box/adapter I need in order to make this a snug, secure fit?

Thanks in advance, Chris

Sorry worked it out after posted.

I can either delete it, or explain. The front of the thermostat comes away from the rest and the back bolts on to the knockout box. Then the frontage of the thermostat just clips back on

You need to put the sensor in a pocket. The sensors do fail, so you should fit a tube which it can slide down into position, so if it fails it can be replaced. Without lifting floor or removing plaster.
