It operates on 24V AC low voltage systems and is fully compatible with millivolt heating applications

While minor oxidation can occasionally be cleaned with fine steel wool

the blower motor running constantly with no heat

it utilizes downstream pressure feedback through an external sensing line to provide accurate

the switch should show a closed circuit (continuity)
