Example of wiring circuit for a coffee urn, thermal protection (a resetable 138c) on real unit is shown here as the switch on the neutral side of the circuit and capillary thermostat (110c) replaced with a switch, keep warm element 500ohm resistor, main element 38.8ohm resistor, 90v neon lamp on main switch and ready light. Ready light illuminates when capillary thermostat reads 110c.
