SEQUENCE OF OPERATIONS
1. To turn the unit on, turn the switch to the on position.
• Power is sent to primary side of the 120vac/16vac transformer.
•
Power is sent to the normally closed high limit.
•
From the high limit power is sent to the normally open contacts of the 12VDC relay.
2.
From the secondary of the transformer 16VAC is sent to the controller
• Power is sent to the red LED (low water indicator light) from terminal 4 of the
controller.
• If the water probe is grounded through water the LED will go off.
• If the water probe is not grounded the LED will remain on and the unit will not
heat.
• If the resistance of the thermistor is higher than the setting of the potentiometer( the
unit is calling for heat) then 16VDC is sent to the coil of the relay and the green LED
(heat indicator light)
• The 12VDC relay will close until the unit reaches temperature
3. With the contacts of the relay closed, power is sent to the 24 VAC transformer.
• The transformer sends 24 VAC to the ignition module.
• Ignition module sends 24 VAC to the Amber LED
• The ignition module will send spark to the igniter and 24 VAC to the gas valve.
• With 24VAC to the gas valve the valve opens and gas is sent to the burner.
• Spark and gas together cause ignition.
• When this happens and the module reads at least 0.7 micro amps DC within 4
seconds, the Amber light will go out and the 24 VAC will remain on the gas valve.
• The unit will heat causing the water to boil and steam to be generated.
• If the module does not see the 0.7 micro-amps in 4 seconds, the module will try
again in 15 seconds. It will try 3 times then lock out.
4. The kettle will heat (build pressure) until the controller is satisfied by the thermistor at the
setting of the potentiometer.
• The controller will then turn off the heat circuit until the temperature of the kettle is
below the setting.
• When the temperature drops below the setting the controller will send 12 VDC to the
relay and the heat circuit will be energized again.
5. To turn the unit off, place the switch in the off position.
• Power will be removed from the controller and the heat circuit will de-energize.
