You can optimise the product's energy
consumption (kWh) by programming the
operating hours. Consider the following
points when creating such a programme:
– Electricity tariff tiers (low-/high-tariff peri-
ods)
– Temperature of the drawn-in air (the
product is more efficient during the
warmest parts of the day)
– Check that the product is actuated by a
low-tariff cable
