9Front LED Indicators
There are three LEDs located on the bottom center of the front of the radiator. These LEDs are very useful for determining the current status of the radiator. See below for possible LED combinations and how to interpret what the combinations mean.
ATTENTION: The LEDs can be disabled using switch 1 located on the rear of the radiator. If you believe there is power to the radiator but there are no LED indications on the front of the radiator, switch 1 has likely been set to the “OFF” position. Make sure switch 1 is in the “ON” position before attempting to check the status of the radiator.
9A Red LED
The red LED is the “Power On” LED. If the Red LED is lit, the radiator has power.
9B Yellow LED
The yellow LED is the “no connection” LED. If lit, the radiator is not connected to a transmitter or another radiator. When properly connected the yellow LED will be extinguished.
9C Green LED
The green LED is the “Signal Present” LED. If the green LED is lit, the radiator is outputting an IR signal into the room. During normal operation the red and green LEDs will be on simultaneously (unless defeated by SWI)
