Should UFH be off for tiling?

[gc100]

Given the cooler weather I’m wondering if I should completely  turn off the UFH for tiling the floors or set it to something like 14. My thinking is at 14 there will be less expansion when heating the house up back to 21 when all done. However I’m worried about adhesive drying too quickly. 
Google only suggests one result saying max of 15 and another saying UFH off but above 5

 

Whats the recommendation?

14 won’t be a problem for tiling 

If you give it 24 hours after grouting before increasing the temperature you will be ok
