1. With the Control Box door open, set the ON/OFF POWER switch on the right side to the ON
position. The Temperature Controller will initiate a self-test for approximately 3 seconds.
Following the self-test, the top display will show the current outlet water temperature of the
Heater and the lower display will show the current setpoint temperature stored in memory
(default = 140°F).
2. Ensure that the Temperature Controller is set to the AUTO (automatic) mode and the AUTO
indicator is lit. If the MAN indicator is lit, press the AUTO/MAN button to toggle the mode
setting. Indicator OP1 should also be lit.
3.
If the lower display does not show the desired setpoint temperature, press the ▲ or ▼
arrow button to change the display to the desired value.
4. Two seconds after
the ▲ or ▼ arrow button is released, the display will blink to indicate
that the Temperature Controller has accepted and stored the displayed value.
