5.14. Sensor management
IN (-) ............................ The terminal number to which the temperature sensor is connected. Option 1
indicates a sensor is not used and options 2 to 9 correspond to terminals C2 to
C9.
connected (yes/no) ... No option shall be selected in case no temperature sensor is connected (to avoid
the program reporting an error when the sensor is disconnected). For some
temperature sensors, this option cannot be changed. The setting depends on the
system configuration. (E.g., when DHW zone is switched on in service level, the
HP sensor is activated, while when the DHW zone is switched off, the sensor
deactivates automatically).
adjustment (°C/bar) ... Temperature sensor offset in case the value measured by the sensor differs from
the real value. This is intended e.g. to compensate for the resistance of a long
sensor cable.
state (OK/error) .......... The sensor state – if the sensor is in an error state (either a too high or a too low
temperature is sensed), the text fault is displayed.
For a pressure transducer only:
range (bar) ................. Pressure transducer range (maximum transducer value).
5.15. Other service settings
password ................... Setting a numeric password to access the service level menu.
Frost protection
When Frost protection is on, the flow temperature to a switched off zone is monitored. Should the outdoor
temperature drop below the value set in the out. temp. parameter, then the heating water temperature to
the zone is kept at the value set by water temp. parameter.
state (active / off) ....... Turning frost protection on/off.
out. temp (°C) ............. Setting outdoor temperature limit below which Frost protection is activated.
water temp. (°C) ......... Heating water temperature kept in a zone when Frost protection is active.
Critical Thermal Store temperature
If the temperature in thermal store exceeds the set critical temperature, cooling will start with heating into
all zones switched on in service menu, i.e. incl. those switched off in user menu. During cooling, the zone
pump is on and the max. temperature is set for the zone. ( Max.t to zone ) Cooling will be finished when
the thermal store temperature drops by 5°C..
temper. (°C) ................ Setting critical temperature in thermal store.
