You don't really have to worry about off flavors from too-warm yeast during bottle conditioning, and the conventional wisdom is 70F for 21 days, after bottling. Darker/stronger beers benefit from more conditioning time.
Don't remember your beer type, are you doing ales and such?
Here is what I've been doing. It works well for me, but I encourage you to at least do some of your beers differently to see what works well for you. Little things we don't know or speak of might make some differences. Untried things might leave us without revelations.
I'm usually about 69°F (20°C) ambient air fermenting them. I'll let the internal do what it want's to do but will externally cool if if it gets to the upper limit of the ideal and looks as if it might exceed it. However it almost always drops back from that high temp quickly. So maybe any cooling I did wasn't even needed.
After bottling, I keep them at about 74°F (23°C) maybe a tad higher for 2 weeks or more, but eventually they just get kept are room temp whatever that is until needed in the refrigerator.
Use the ideal temp range of your yeast for a guide. I suggest you get that from their website and not the sachet. I've ask about the differences I've found and their response seems reasonable to me.
