Power Control Mode
To turn on in Power Control mode, press the
button. The red light will illuminate and the
heater will start (takes 2-3 mins). Regulate the
heat output manually by rotating the rotary
knob. Turn off with the button. In this mode,
the heater runs continuously and will not cycle
on and off. This can be advantageous, as cycling
on and off can consume more battery power.
Belief Diesel Air Heater Quick Reference Guide
You can start the heater in either Power Control or Temperature Control mode.
Starting takes 2-3 min per start attempt and the heater will attempt to start twice
before an error is shown.
Temperature Control Mode
To turn on in Temperature Control mode, press the button. The green light will
illuminate and the heater will start (takes 2-3 mins). In this mode, the heater is
thermostatically controlled and maintains a target temperature set using the rotary
knob. Regulate the target temperature by rotating the knob. Set the knob in the
middle to start, then adjust up and down to achieve the desired target temperature.
Turn off with the button. In this mode, the heater can cycle on and off, which can
consume more battery power, particularly if heating a small space or when it is not
very cold.
Heater Care: All diesel air heaters need to be run at a high power setting
for around 15-20 minutes every 6-8 hours to prevent carbon build up.
Troubleshooting
When you turn on the heater, it does a self test. If any faults are found, the red LED
will immediately flash an error code. There will be a series of flashes followed by a
pause, then the series of flashes will be repeated. If this happens, count the flashes
and refer to the error codes below. If there are no errors found when you turn on the
heater, the heater will go through 2 start attempts over a period of about 6 minutes.
If the heater cannot ignite, the red LED will flash slowly and continuously. See the
trouble shooting guide over the page.
