Power is from neutral (N) through relay #2 (single / upper oven) and relay #5 (lower oven) to the 8 - position selector switch contact “J” to contact “6" to line L1. 2-POSITION SELECTOR SWITCH on the VESO is used to select manual or timed bake.
  • Page 27 L2 ( L1 ( BLK) Selector Bake position closes Switches 1-L2, 2-N, and 3-E. The Thermostat closes Switches Cy1-Cy2, which cycles with the oven temperature powering Relay 1 and the Oven cycle light. When Relay 1 closes, it powers the Bake Element at 208v/240v, and with the Broil Element in series across a 120v circuit, it powers the inside Broil at 50v.
