That would be interesting trying to get the indoor blowers to run at the same speed. You would need to add a relay system.Originally posted by ambarton
some of the coils we have to do this and some not. most times they send a txv that is a bolt on and a unit that is not and sometimes the other way around. Affinity is still a good piece of equipment. i'll give it a whirl on the nitrogen and use it on my next install. Tried to sell the builder on 2 Affinity 8T's and making a 4 stage cooling 6 stage heating, kinda like the soon to come modulating gas furnaces except with a heat pump.
