To adjust the desired temperature, press the left or right arrow buttons. The left arrow button lowers the desired temperature, and the right arrow button raises it. The adjustment range is from 48 to 93°F (8 to 34°C).
To turn the heater off, press the POWER button again. The heater will initiate a 5- to 8-minute cooling cycle.
The controller has a real-time diagnostic feature, and will automatically display fault codes as they happen (e.g. 48 Check Fuel Pump). The red LED will illuminate, indicating that maintenance is required.
The controller has a programmable run timer that will display a maintenance message on the LCD after the set time limit when the heater is off. See Fig.. The fault codes and maintenance messages will not prevent the heater from operating, but they reflect conditions that should be addressed promptly.
