For the most effi cient operation, keep the windows and doors closed
including unused areas where possible. They not only help to insulate
against heat and cold, they also reduce dust, pollen and noise.
Occasionally allow fresh air into rooms and offi ces that are closed off.
Should you wish to leave your air conditioner on over night during the
winter. Set your thermostat down by 2
o
C to 4
o
C when going to bed and reset
to your normal setting upon arising, as there is no reason to pay for extra
electricity when you are under the blankets. This can also apply during the
summer nights and therefore raise the temperature by 2
o
C to 4
o
C.
On days when extreme conditions of High or Low temperatures prevail and
the home is unoccupied, it can be practical to leave the air conditioner ON.
However to reduce energy costs, set the temperature up 2
o
C to 4
o
C (Cool
Mode) for summer and down 2
o
C to 4
o
C (Heat Mode) for winter and reset
to your normal setting upon returning. This will provide a more comfortable
situation and reduce the high heat load as the Air Conditioner not only has
to cool or heat the air, it also has to cool and heat the furniture, walls, fl oors
and ceilings.
The normal setting recommended is 22
o
C for both summer and winter.
By raising the set point by 1
o
C in summer or lowering the set point by
1
o
C in winter can save approx. 10% on electricity costs.

If your air conditioner has zones fi tted, always turn off the zones you
aren’t using as this will save energy by the air conditioner not having
to operate as long.
