Hi. I arrived to this forum searching for a solution to my Genvex issue. I moved to an apartment with this system installed with a controller "Optima 251". The landlord doesn't have a clue about the system, he sent a "plumber" that only reset the unit (same thing I did before). So I've been looking to solve this myself.
Currently, room temperature in the apartment keeps showing 25-30 degrees no matter what settings I pick. The apartment faces West, so during the afternoon it gets super hot, but I believe there has to be something wrong with the system since the temperature outside is about 12-15 and inside it keeps measurng circa 26 and sometimes up to 30.
I've already turned all heating functions off, all thermostats are all the way down to the minimum (5). I tried setting supply and exhaust to 100%, supply 100% exhaust 0%, vice-versa, etc. None make a difference. And we are still sweating in here!
