Re: [A/S] A/C unit

This unit had the digital controls mounted INSIDE the inside cowling, not on the wall. These systems can be modified with a new control board to replace the original design and a new wall thermostat. This design was used shortly before duo therm introduced the wall mounted digital comfort control.
