dirty condenser signal light
I am looking to install a light to signal when the condenser is dirty so the user could perform maintanence. It would come on before the high pressure cutout trips. I see two possibilities. One being a fan cycle control that makes contact on rise of pressure just below the safety cutout and lites the signal that the unit needs cleaning. Or a temp control with probe strapped to the hot gas line doing the same thing.
My question is which would be prefered and where would I sample the pressure or temperature to initiate the sequence. Thanks, Ken
