[1] Weather dependent set point
The weather dependent set point field settings define the parameters
for the weather dependent operation of the unit. When weather
dependent operation is active the water temperature is determined
automatically depending on the outdoor temperature: low outdoor
temperatures will result in warmer water and vice versa. During
weather dependent operation, the user has the possibility to shift up
or down the target water temperature by a maximum of 5°C. See the
operation manual for more details on weather dependent operation.
Field settings for heating operation
■ [1-00] Low ambient temperature (Lo_A): low outdoor
temperature.
■ [1-01] High ambient temperature (Hi_A): high outdoor
temperature.
■ [1-02] Set point at low ambient temperature (Lo_Ti): the
target outgoing water temperature when the outdoor
temperature equals or drops below the low ambient
temperature (Lo_A).
Note that the Lo_Ti value should be higher than Hi_Ti, as for
low outdoor temperatures (i.e. Lo_A) warmer water is
required.
■ [1-03] Set point at high ambient temperature (Hi_Ti): the
target outgoing water temperature when the outdoor
temperature equals or rises above the high ambient
temperature (Hi_A).
Note that the Hi_Ti value should be lower than Lo_Ti, as for
warmer outdoor temperatures (i.e. Hi_A) less warm water
suffices.
Field settings for cooling operation
■ [1-05] Weather dependent for cooling function enable (1)/
disable (0)
■ [1-06] Low ambient temperature (Lo2_A): low outdoor
temperature.
■ [1-07] High ambient temperature (Hi2_A): high outdoor
temperature.
■ [1-08] Set point at low ambient temperature (Lo2_Ti): the
target outgoing water temperature when the outdoor
temperature equals or drops below the low ambient
temperature (Lo2_A).
Note that the Lo2_Ti value should be higher than Hi2_Ti, as
for low outdoor temperatures (i.e. Lo2_A) less cold water
suffices.
■ [1-09] Set point at high ambient temperature (Hi2_Ti): the
target outgoing water temperature when the outdoor
temperature equals or rises above the high ambient
temperature (Hi2_A).
Note that the Hi2_Ti value should be lower than Lo2_Ti, as
for warmer outdoor temperatures (i.e. Hi2_A) colder water is
required.

[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.
CAUTION
The disinfection function field settings must be configured
by the installer according to the applicable legislation.
■ [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.

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.
When the 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 the applicable legislation.
CAUTION
Make sure that the disinfection function start time [2-02]
with defined duration [2-04] is not interrupted by possible
domestic hot water demand.
