This listing is for a function switch for a PTAC air conditioner p/n EL-B-1133-B or ASR6179-10 manufactured by SOLLEAM. This switch came from an ICE AIR wall A/C . It controls 2 high/ low fan speed, heat/cool settings and more(see photos). The turn stem is made of copper, so it’s not going to break like plastic one. The switch looks like new, very clean. It was tested and works fine. The thermostat for this unit is listed by me as well. Please check the photos for technical data and general appearance.
