Sleek, Classy Ceiling Cassettes

The ceiling cassettes really deliver with space saving and a sleek, classy design. They even work well in 100+ year old lath and plaster ceiling as pictured here. Still getting the hang of the controls and waiting to see what its like in different temperatures but initial installation and operation is great.

Dual or multiple zone

Two ceiling handlers with 18K condenser works perfectly. I had an issue where the system was not working properly from room to room and I could not identify the issue. After contacting tech support and testing and rechecking everything, the problem was electrical was backwards from the refrigeration lines (A & B reversed). I originally did not identify A & B on the refrigerant lines running to the condenser. Once I switched electrical A and B, all worked as it should.
