try to achieve.
Set and Forget or Customise. You can,
for example set this to 21oC. A typically
ecient setting to provide good 'year round'
performance, or you can adjust seasonally if
you wish.
In Summer, if you select a Set Temperature
of 18oC for example, the house will reach this
temperature quickly. The system will turn o,
preventing warm air being introduced. The
system starts again when the air supply is
cooler than 18oC.
In Winter, You could select a higher Set
Temperature of 23oC for example. When, or if,
there is heat available from the air supply, the
system will be in Heat Recovery mode and will
try to reach 23oC in the home more quickly.
Note: The system will continue to operate
even if the roof space is cooler than the house.
The system will reduce the air supply rate to a
programmed minimum requirement when the
air supply is cooler. The air ow rate can reduce
further if you have Heat Retention activated,
however this may aect the performance of
the system.

the fan speed (air supply rate) when there
is enough heat to recover from the ceiling,
and the house is not yet at, or above the Set
Temperature (measured at the keypad).

Useful Tips
System Performance
Your DVS® will help to provide a healthier,
drier living environment.
Ventilation, heating (in cooler months) and
cooling (in warmer months) are all keys
to providing a drier, healthier and more
comfortable living environment.
Winter: (or cooler months). Your DVS® is
programmed to supply enough ventilation for
your home based on the size of your home. If
the home is now drier, you may wish to reduce
the level of ventilation using the Fan Speed
adjustment (see page one). The ideal being to
have the minimum level of ventilation while
retaining a drier, healthier home.
If the home is not yet drier, you can increase
the Fan Speed adjustment to ventilate at a
higher level.
Summer: (or warmer months). Experience has
found that increasing the Fan Speed setting
to higher levels provides better ventilation in
warmer months.
Note: Also see Set Temperature on page one.
If you feel you have system performance
issues e.g. wet windows, turn the system o
and call DVS® so that we can assist.
