Thoughts on using Ilford Bromophen in a warm darkroom

I've never used this paper developer, but I'm thinking about giving it a shot because I read that it produces a slightly warm image tone with most papers. However, I just read the instructional info on Ilford's paper developers and they don't recommend using this formula in a warm/hot environment. Since my darkroom runs at about 80 - 82F ambient temp during the summer months, I was wondering if anyone has any experience with using this particular paper developer in warm temps? How warm/hot is hot? Ilford doesn't say...
 
Bromophen is my standard paper developer. The temperatures you indicate won't be an issue, consistency is the main thing.

The exact wording is:
"BROMOPHEN developer is designed for use at
ambient room temperatures, nominally 20ºC/68ºF.
We do not recommend its use for high
temperature or machine processing applications."
I read "high temperature or machine processing applications" as meaning the sorts of applications that emphasize speed and throughput - the ones usually found in industrial/commercial environments.

Of course, if my understanding about UK weather is correct, even 20C/68F might be considered at least a warm temperature environment .....
 
Thanks for the input.

@MattKing, yeah, that's the way I read it, too, but the wording leaves "high temperature" open-ended.
 
High temp is for the machine processing chemicals, up to 40°C
 
I've used it at 75F even warmer no problems. Like Craig says not for use in machines (like the old Ilford 2150). I love this stuff. Keeps nicely in full bottles. Dilute 250mL of stock to make 1 liter of working solution. So a 5L package makes 20 liters of working, very economical. I develop for 2 minutes at 68°F.
 

I am not sayíng we regard the above temperature as dangerous but warnings are announced on public tannoys and the Accident and Emergency depts are alerted in all U.K hospítals

At 21C I am convinced I have seen a guy in a cloak with a scythe walking the streets but it might have been my near comatose condition brought on by the heat

The 2000RT chemicals for machine processing say the development time at 40°C is 12 seconds. At 20°C ( the coldest they recommend) the time increases to 46 seconds.
