It is recommended using screened cable in electrically noisy areas.
Do not install fan coil unit in a location where electromagnetic waves may be directly emitted towards infra-red
receiver on the unit.
Install the unit and components as far away as is practical (at least 5m) from any electromagnetic wave source.
Use shielded sensor cable in where electromagnetic waves exist.
Install a noise filter if necessary.
