FIRESTAR COMBUSTION CONTROLLER - VERSION 6.7 • OPERATION MANUAL
LED Display Alarm Definitions
The LED display will display an alarm message when abnormal conditions
appear. If any of the following messages appear, take corrective action.
FIRE OUT
When the system is calling for heat, if the temperature in the Reaction
Chamber has been below 300˚F for 60 minutes and does not rise more than
5˚F, or after three hours even if the temperature is rising, the combustion
fan will turn off and the primary air actuator will close. This alarm is reset by
opening and closing the furnace door, or by turning the controller off and back
on.
HIGH TEMP1
The temperature sensor connected to the FireStar combustion controller
has detected that the water temperature is above 200˚F. The controller will
continue to alternate between HIGH TEMP1, the water temperature, and the
Reaction Chamber temperature until it senses that the water temperature has
fallen below 195˚F.
HIGH TEMP2
The external high limit sensor has sensed that the water temperature is above
200˚F and has disconnected power to the combustion fan and actuators.
The controller will continue to alternate between HIGH TEMP2, the water
temperature, and the Reaction Chamber temperature until it senses that the
external sensor has reconnected power. This will normally happen when the
sensor cools to 165˚F.
If this alarm occurs often, lower the water temperature setpoint.
LOW WATER
Check the water level at the sight gauge and, if necessary, add water according
to the Water Quality and Maintenance section of the Owner’s Manual. If
adding water does not clear the LOW WATER alarm, it can be temporarily
overridden until a repair can be made (see the Setup Mode section, variable
#18).
NOTE: If water is added to the outdoor furnace and/or system, the system water should
be tested and 1650XL Inhibitor Plus should be added (if necessary) to maintain the
recommended level of protection.
