I had an LG Multi F system installed over the summer. It has 2 branch units running a total of 6 zones(5 ceiling cassettes and 1 wall unit). None of the units stop when they reach the set point. I thought it might be an issue with using the wireless remote so I added LG's simple wall thermostat to the wall unit. I also added "remote" temperature sensors to the ceiling units thinking that they were causing this. Even though the units are reading the room temperature correctly, they are still heating well past the set point(8-10 degrees). Any ideas on what could be going on?
