Air Conditioning Install Binary Switch
|
We also installed the binary switch on the drier at this time. Once wired, this will disengage the compressor clutch in case of an extreme low pressure condition (refrigerant loss) or excessively high head pressure ( 406 psi), to prevent costly compressor damage or hose rupture. If we were running an electric fan, we’d use a trinary switch, which combines the high/low pressure protection with an electric fan operation signal at 254 psi. These switches are extremely important as the a/c system relies on refrigerant to carry lubrication through the system. View Related Article
