LED indication

Function test
The LED indicator shows wheth er the 100M is in
op er a tion or not. When testing sensors and controller, the
con trol status and faults are shown.
Control status
At normal operation with the function switch in the
positions , the indicator lights.
Constant light: The fl ow temperature is in the neutral zone
and the motor does not receive sig nals. The valve is not
activated.
Constant light with two interruptions: The fl ow temperature
is below the neutral zone. The motor opens the valve.
Constant light with three interruptions: The fl ow
temperature is above the neutral zone. The motor closes
the valve.
Note! The indication does not follow the signals.
Test of controller and sensors
Turn the function switch in position
sec. the lamp will fl ash and show the test result. The result
is shown every third sec.
No light: The controller is defective or the fl ow
temperature sen sor is not mount ed.
Constant light with 1, 2 or 3 intervals: The number of
in ter vals must correspond to the number of con nect ed
sen sors. If the number is not correct, one or more sensors
might be short-circuited or disconnected.
Constant light: The controller is defective.
