The circuit can also be installed in a plastic housing (NOT A METAL BOX) e.g. WCAH2851.
Place the housing in a place where there are few metal parts. It may be the case that after installation, the circuit
will have to be retuned. This is because of the influence of metal parts in the vicinity of the circuit.
