Unmatched Maintenance Simplicity
With a top panel and an indoor coil that can be easily removed, get faster access to the core parts of the unit needed for service. You only need to remove two screws!

Less Complex Electronics
Having only two integrated printed circuit boards  means the electronic components are less complicated. One is the main control board, and the other is the function board for the 24V interface, dip switch, wired controller and LED display. 

Easier Access to Electric Heater
This single-piece construction enables easy installation and maintenance.

Modular Slide Design
The indoor coil can be easily pulled out through the slide track for quick and easy maintenance
