Since each switch (Element A and B) is adjusted independently via its own calibration screw

This heavy-duty component is built to withstand high operating temperatures

though it has a higher burst pressure rating for safety overhead

which is functionally identical to the 312867H/U model

Replacing a faulty temperature actuated switch with this genuine HH19ZA201 Carrier part restores secondary safety cut-out functionality
