Temperature Control Test Procedure

1.Disconnect the dispenser from the power source.

2.Check the voltage across terminals 3 & 4 of the electronic control circuit board with a voltmeter. Connect the dispenser to the power source. The indication must be 200 to 240 volts ac for 200 to 240 volt models.

3.Disconnect the dispenser from the power source.

If voltage was present as described, proceed to #4.

If voltage was not present as described, refer to the Wiring Diagram and check the dispenser wiring har- ness.

4.Connect the dispenser to the power source .

5.Observe the red indicator on the electronic control circuit board.

6.Disconnect the dispenser from the power source.

If voltage was not present as described, contact Bunn- O-Matic to order an electronic control assembly tem- perature sensor, and triac assembly for evaluation and proceed to #9.

9.Replace the electronic control assembly and tem- perature sensor.

NOTE - Each electronic control assembly is calibrated to a temperature sensor. Both components MUST be replaced as a set.

10.Check the voltage across the tank heater terminals with a voltmeter. Connect the dispenser to the power source. The indication must be 200 to 240 volts ac for 200 to 240 volt models while the red indicator on the circuit board is on or blinking.
