My Cooler Controller now shows temperature in deg C…?
A. Reset the unit: – For newer units, simply push the Reset button. The Reset button is labeled, and it is located below and to the right of the LCD (it is not on the left side of the LCD). – For older units, without a Reset button: disconnect electrical power at the circuit breaker panel for 10 to 15 minutes. This step may have to be repeated a few times. If the unit does not properly reset after repeated attempts, then the unit has failed and it should be replaced.
