To change the Maximum Setpoint Limit (Max Setpoint) for the temperature setpoint:
Step 1: In service mode press the “Select” button until “Max Setpoint” is displayed.

Setting the water temperature

highly recommended that the

possible for the needs of the
installation. Make sure the
water heater control display is
not in a public area that can
