[2] Disinfection function
Applies only to installations with a domestic hot water tank.
The disinfection function disinfects the domestic hot water tank by
periodically heating the domestic hot water to a specific temperature.
■ [2-00] Operation interval: day(s) of the week at which the
domestic hot water should be heated.
■ [2-01] Status: defines whether the disinfection function is
turned on (1) or off (0).
■ [2-02] Start time: time of the day at which the domestic hot
water should be heated.
■ [2-03] Set point: high water temperature to be reached.
■ [2-04] Interval: time period defining how long the set point
temperature should be maintained.
[3] Auto restart
When power returns after a power supply failure, the auto restart
function reapplies the user interface settings at the time of the power
supply failure.
Note that with the function disabled the schedule timer will not be
activated when power returns to the unit after a power supply failure.
Press the pr button to enable the schedule timer again.
■ [3-00] Status: defines whether the auto restart function is
turned ON (0) or OFF (1).
[4] Space heating off temperature
Space heating off temperature
■ [4-02] Space heating off temperature: outdoor temperature
above which space heating is turned off, to avoid
overheating.
[9] Cooling and heating 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.
■ [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.
CAUTION
The disinfection function field settings must be configured
by the installer according to local and national regulations.

WARNING
Be aware that the domestic hot water temperature at the
hot water tap will be equal to the value selected in field
setting [2-03] after a disinfection operation.
If this high domestic hot water temperature can be a
potential risk for human injuries, a mixing valve (field
supply) shall be installed at the hot water outlet connection
of the domestic hot water tank. This mixing valve shall
secure that the hot water temperature at the hot water tap
never rise above a set maximum value. This maximum
allowable hot water temperature shall be selected
according to local and national regulations.

NOTICE
It is therefore recommended to leave the auto restart
function enabled.
NOTICE
If the benefit kWh rate power supply is of the type that
power supply is interrupted, then always allow the auto
restart function.
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.
