If this switch is noted to be in the actuated position upon
power-up, the controller will not start furnace operation and
an LED error flash cadence is set to indicate the problem.
Further, during a reset operation the electromechanical
reset switch must not only be actuated for one second or
longer but the switch must be released before the IBC
assembly will reset.
The temperature sensor inputs are hardware biased
towards over-range or under-range conditions as
appropriate. In the event of a disconnected sensor, the
firmware can detect that the sensor is missing or shorted by
testing for sensor under-range and over-range conditions, as
is appropriate for a given sensor.
The IBC assembly will detect that the water temperature
sensor is missing and will shut down the furnace, and an LED
error flash cadence will be set to indicate the problem.
The potentiometers on the IBC assembly that are used to set
the water temperature high limit and water temperature low
limit are monitored for reversed settings. If the water
temperature high limit is set to a lower temperature than the
water temperature low limit temperature setting, the IBC
assembly will detect this reversed setting condition and the
furnace will be shut down resulting in a LED error flash
cadence to indicate the problem.
LED Indicator Error Cadences
In order to communicate diagnostic information to the
user of the Earth Outdoor Furnace, the LED indicators that
are visible on the front panel of the IBC controller assembly
will flash as required in order to indicate various
operational alerts and alarms. The error cadences and their
meanings are as follows:
Water Jacket Temperature below 150°F
Call for heat amber LED will pulse
