CTEK Assist for NANOGRID™ AIR
The NANOGRID AIR is flashing red even when it’s connected to the energy meter and the charger.
Make sure the port in the energy meter is activated and running the correct protocol.
Please note: If you have a Kamstrup Omnipower energy meter with an P1/RJ12 interface you need to install a Active P1 splitter from Homewizard to allow power and signal boost to the NANOGRID AIR.
