Press the switch once to select HIGH-level
heating. Press the switch a second time to select
LOW-level heating. Press the switch a third
time to shut the heating elements OFF.
When the HIGH-level setting is selected, the heater will
provide a boosted heat level during the first four minutes
of operation. Then, the heat output will drop to the
normal HIGH-level. If the HIGH-level setting is selected,
the system will automatically switch to LOW-level after
approximately 60 minutes of continuous operation. At
that time, the number of illuminated LEDs changes from
two to one, indicating the change. The LOW-level setting
will turn OFF automatically after approximately 45 min-
utes.
