What to do if the Green LED is OFF (TD1) or all LEDs are OFF (TD2) on my Magnetrol Thermatel TD1 Switch?
If the green LED is off (TD1) or all LEDs are off (TD2) on your Magnetrol switch, it could be due to a lack of power. First, verify the power supply. Then, check the wiring at the wiring terminals to ensure everything is properly connected.
Why is the Red LED blinking and showing ?3,6 mA or ?22 mA (TD2) on my Magnetrol Thermatel TD1 Switch?
A blinking red LED accompanied by a reading of ?3,6 mA or ?22 mA (TD2) on your Magnetrol switch indicates that an instrument error has been registered. Try changing the switch settings, as this may return the unit to normal operation. If the problem persists, you should consult the factory.
How to fix a Magnetrol Thermatel TD1 when the Red LED does not turn ON?
If the red LED on your Magnetrol switch isn't turning on, it's possible that the switch point cannot be established for air flow detection. Ensure that the probe is extended into the flow. You might also need to change the Heater setting to “-”.
