tion electrical cable is 50 m. A normal 2-wire cable can be used. The external probe should preferably be installed on
the North, North-West wall or that facing the largest area of living room. The probe must never be exposed to the early

near windows, doors, ventilation openings, flues or heat sources that could affect the reading.
