The latest batch of reverse cycle air conditioners from Panasonic are a smart bunch. The range features a new Econavi sensor that moderates temperature according to room usage.

This is claimed to deliver up to 30 per cent energy savings during cooling and even more, 40 per cent, while heating.

The air purifying system with patrol sensor is said to de-activate more than 99 per cent of dust, bacteria, mould or virus.
