UK Commissioning UFH after laying slate tilies

[ajn9000]

I've had a look through threads but cannot find anything on this.
Lots of info on commissioning screed, but I can't find anything on post-screed-commissioning.
The question is: what would be the best UFH commissioining process after laying 10mm slate tiles? 10mm slate tiles on a solid 6mm adhesive bed, onto Mapai WP200.
They are laid onto a screed which has been thoroughly dried (text book heat stressed >12 months ago).
Q1: how long to wait to turn on UHF
Q2: how/when to increase UFH temp
Many thanks!

Basically it’s just like commissioning a screed. Same slow temperature increments each day and then slow lowering of temperature. Most manufacturers say commissioning of adhesive etc at around 14 days. To prevent shock to adhesive and grout.
