■
Make sure the domestic water is only heated up to the
domestic hot water temperature you require.
Start with a low domestic hot water storage
temperature set point, and only increase if you feel
that the domestic hot water supply temperature is not
sufficient for your needs (this depends on your water
using pattern).
■
Make sure the domestic water is not heated
unnecessary. Start with activating automatic storage
during night (default setting). If it seems that the
domestic hot water night storage operation is not
sufficient for your needs, an additional scheduled
reheat during daytime can be set.
[9] Heating and cooling set point ranges
The purpose of this field setting is to prevent the user from selecting a
wrong (i.e., too hot or too cold) leaving water temperature. Thereto
the heating temperature set point range and the cooling temperature
set point range available to the user can be configured.
CAUTION
■
In case of a floor heating application, it is important to
limit the maximum leaving water temperature at
heating operation according to the specifications of
the floor heating installation.
■
In case of a floor cooling application, it is important to
limit the minimum leaving water temperature at
cooling operation (field setting of parameter [9-03]) to
16~18°C to prevent condensation on the floor.
■ [9-00] Heating set point upper limit: maximum leaving water
temperature for heating operation.
■ [9-01] Heating set point lower limit: minimum leaving water
temperature for heating operation.
■ [9-02] Cooling set point upper limit: maximum leaving water
temperature for cooling operation.
■ [9-03] Cooling set point lower limit: minimum leaving water
temperature for cooling operation.
