A high pressure switch works to protect the air conditioner (a/c) compressor from operational conditions, and now we also can protect the whole a/c condenser unit (outdoor unit) from theft and vandalism. The safeguard can be accomplished by installing another high pressure switch on the high pressure liquid line or close to the a/c indoor air handler as shown and wired to the central box of the alarm system. |
