The ‘PRIMARY
STATUS L.E.D 1’ shows the first digit (tens) of the fault code and ‘
PRIMARY STATUS L.E.D 2’
shows the second digit (ones), e.g. fault code 35 would display as 3 flashes on ‘
PRIMARY STATUS L.E.D 1’ and
5 flashes on ‘
PRIMARY STATUS L.E.D 2’.
Both L.E.D’s will flash together for the first three flashes and then ‘PRIMARY STATUS L.E.D 1’ will stop while
‘PRIMARY STATUS L.E.D 2’ will flash two more times, example flash sequence below.
Primary Status L.E.D 1

control board or reset through a Networker controller if connected.

The Kaden Networker controller is used as a Wired Wall Thermostat and is also the interface to

Gas Heaters. A spare Networker should be kept on hand for such purposes.
