If it's an incremental degree each time on the room stat, it shouldnt let much hot water through each time. It'll just keep topping up the system with a burst of hot water which should be pumped evenly quite quick.

.... Is the way I understood it.

Needs to be controlled at the manifold. You must be able to lower/set flow temp there. Lowest setting is 28 deg normally. Set wall at 18 deg and control the flow temp over many days. Check floor and flow temp with a laser temp probe morning and evening.

Working on room stat only could be fatal, and I wouldn't recommend it at all.

I'll have a look at the manifold tonight and see what I've got.
Do tiles need to be grouted before this is done?

Ideally yes. Floor surface temp needs to be 18 deg or below when grouting. Best to get it grouted and wait 7 days and the turn on ufh and ramp up slowly using flow controlled temp

Any idea how much floor I should attempt to grout at a time as an amateur. Tiles are smooth but non slip finish so may not wipe up like a glazed tile. I dont want to do too much then find it's set too hard to clean up easily. But at the same time obviously want to get it done asap and not spend all day washing out buckets and paddles etc
Any recommendations on grout guessing flexible and will need to be grey coloured I think, but are any makes better than others _ anything to steer clear of?

Thanks

Everyone will give you a different answer to which grout to use. I would say you won't go to far wrong with bal grout.
Try doing about 5m2 at a time and see how you go. Don't use to much water when washing off. Bal grout doesn't set to fast.

make sure the grout is flexible...
