[9] Automatic temperature compensation
First
code
9
If needed, it is possible to adjust some thermistor value of the unit by a correction value. This
can be used as countermeasure for thermistor tolerances or capacity shortage.
The compensated temperature (= measured temperature plus compensation value) is then
used for controlling the system and will be displayed in the temperature read-out mode.
 [9-00] Leaving water temperature compensation value
 [9-01] Domestic hot water tank compensation value
 [9-02] Thermo ON/OFF admission

By changing this value the operation range for space heating operation can be modified.
If the ambient temperature becomes higher than (24°C + the value of [9-02]) no space
heating is possible.
Space heating can be requested as long as the ambient temperature is lower than (20°C +
the value of [9-02]).
Example: [9-02] = –2°C
