sensor input to IR or inputs from the add-on digital input module (if
present).
External blocking input (sensor list)
.................................... Setting the terminal to which an input used for blocking the DHW-E
heating externally will be connected. It is possible to select any free
input to IR or inputs from the add-on digital input module (if present).
5.13. Settings for thermal store heating
on (active/off)
............. Switching on Thermal Store zone on service level.
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.
