Steam Interlock Relay Coil
A second wire from the J20 connector goes to the steam interlock relay coil. There is no voltage to the steam
interlock relay coil when the control is not cycling the steam generator on. Therefore, the 2 heat elements
and the blower motor operate through their NC contacts.
