Heater Circuit Schematic 20-AMP - 230/208 VAC,
3.30/3.20 KW Heat (RAK3203A).
When the relay contacts close, the circuits to the
1.0 KW and 2.3 KW heaters are completed from L1
through the jumpers between terminals #1 and #2,
#2 and #6, and back to L2 through terminal #7. This
makes a total of 3.30/3.20 KW of heat available to
heat the room.
