outputs to the tent. When the temperature within the tent reaches
the setpoint, an amber AT SETPOINT light glows. When the
temperature sensor registers this temperature, the heater begins
to regulate its output so that the temperature is maintained.
BATTERY CHARGING light
When lit, indicates the heater assembly battery is being charged
by the TEG. While this light is lit, the heaters electronic controller
does not allow the heater to respond to the LOWER-HIGHER
control knob settings unless all the electrical requirements of
heater operation and battery charging are met.
BATTERY CHARGED light
When lit, indicates the heater assembly battery is fully charged
and the heater will respond fully to the changes in tent
temperature or changes to the LOWER-HIGHER control knob
settings. Once this light comes on, the heater can be turned off
with assurance that the battery is fully charged and there will be
enough power for the next startup.
SYSTEM FAULT light (red)
When this advisory light is pulsing and the related audible alarm
(also located within the tent control assembly) is buzzing, it
indicates the heater assembly sensors and the electronic heater
control assembly have detected an unsafe operating condition
and the heater has begun to shut itself off. This advisory light
and audible alarm provide a sequence of from I to 10 pulses that
correspond to diagnostic codes explaining the cause of SYSTEM
FAULT. See back of the heater control assembly for diagnostic
AT SETPOINT light (amber) When lit, indicates the interior tent temperature is at or above the
LOWER-HIGHER control setting.
