SEQUENCE OF OPERATIONS
1. To turn the unit on, turn the switch to the on position.
• 115 VAC is sent to primary side of the 120vac/16vac transformer.
115 VAC is sent to the normally closed high limit.
•
From the high limit 115 VAC is sent to the normally open contacts of the 12VDC relay
•
and the L1 and L2 terminals of the ignition module.
2. From the secondary of the transformer 16VAC is sent to the controller.
• 12 VDC 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, 120VAC is sent to the blower and primary coil of the
120VAC/24VAC transformer.
• From the secondary of the 24VAC transformer 24 VAC is sent to the normally open
contacts of the air switch.
• When the air from the blower closes the air switch, 24VAC is sent to the Th terminal of
the ignition module.
4. With both 120VAC (at L1 and L2) and 24VAC (at Gnd and Th) to the ignition module then
120VAC will be sent to the surface igniter.
5. After the ignition module has been energized for 24 seconds the module will send 24VAC to
the gas valve.
• The gas will touch the hot igniter and ignite within 4 seconds. If the module does not
detect flame in 4 seconds, 24 VAC is removed from the gas valve. Module then locks
out.
• The kettle will 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.
