Observation:
With the DHW thermostat set to MIN (fully anti clockwise) the small triangular cut-out on the potentiometer should be in the 4-5 oclock position.
With the DHW thermostat set to MAX (fully clockwise) the small triangular cut-out on the potentiometer should be in the 7-8 oclock position.
Does the control knob turn the potentiometer to the correct positions?
