Assuming you used the RC-212 it came with 88F is just past the top of the recommended temperature range, but much of that heat is coming from the super active fermentation, and you are already down to 1.020, so your 'bonfire of fermentation is running out of wood' and you'll be back within the temperature range in no time. I think you will be fine. I'm guessing that doing the double batch allowed for even more heat to build up from the fermentation. As I type this I recall you swapped out for BM4x4 or something else as you could not find one of the packs of RC-212, if so you are a bit further out of range, but again I think that the worst of the heat is coming from chewing through 45 "points" of alcohol in 12 hours, and that will slow down, since you only have 20-26 points left:
RC-212: "Isolated from the Burgundy region of France. Recommended for red varieties where full extraction is desired. Color stability is maintained throughout fermentation and aging. Aromas of ripe berry and fruit are emphasized while respecting pepper and spicy notes, as well. Alcohol tolerance of 16%. Ferments well from 59 to 86 degrees."
"BM 4x4 is a new yeast blend created by Lallemand, designed to provide all of the benefits and flavors of the BM45 yeast strain, along with a much more reliable and consistent fermentation. This means that you'll be getting all of the flavors of jam, rose petals, and cherry liquor with a stronger fermentation with less risk of a stuck or sluggish fermentation. This is a blend between the traditional BM45 and a complimentary strain, chosen for its fermentation kinetics. Positive interaction between these strains means a more dependable fermentation, along with increased aromatic intensity, color intensity, and length of finish. Ideal fermentation temperature is between 64-82°F. This strain will enhance varietal character, and mouthfeel in a wine. Alcohol tolerance is 15%."
