Password
Password selection and enabling. The command disables the use of keys + and –, so that data
cannot be modified. Enter the number (1900... 1999) using the + and – keys.
To delete password press + and – simultaneously until the dashes reappear.
If the + or – key is pressed when the password is enabled, the display will show a request to enter the
password. The + and – keys can only be used after entering the proper password. If no key is
pressed in the next 15 minutes, the password will be automatically re-enabled.

Display of values and operating data
The controller displays all values measured by the detectors as well as all data that help understand
the system’s operating status:
• Actual room temperature – Rt (if
B3
is connected) or flow temperature – Ft
(if only
B1
is connected).
• Actual humidity
(if
B6
is connected)
• Calculated flow temperature
based on Heating setting (if
B3
and
B1
are connected).
• Calculated flow temperature
based on Cooling setting (if
B3
and
B1
are connected).
• Actual temperature
measured by detector
B1
(only if
B3
and
B1
are connected).
• Actual outside temperature
(only if
B2
is connected).
• Preheating desired and actual
temperature, only if
B4
is connected and
• Dew point
desired and actual temperature, only if
B4
is connected and
• Setting of
desired battery frostprotection temperature and actual value, only if
B7
is connected
•
Output Y load value: Preheat. or Heat. or Ht.P.Hea. or Cool. or Frostprotection
•
Output Ys load value: DampTemp. or Recuper. or Dehumid.. or Humid.
•
Output Mu load value: Humidification
•
Battery frostprotection function load value

Data recording
Every hour and with every mode change the controller stores a set of data indicating operating
status:
– Current date and time, type of recording (new hour or mode change)
– Current mode: On or Off; current season: Winter or Summer.
– Controller’s desired and calculated values
– Values measured by the detectors connected
– Outputs Y and Ys load value.
The controller is able to store 32 complete recordings, and the latest recording causes the oldest to
be deleted. If the display is not on page 1, the controller will perform the new hour recordings, but not
the mode change recordings, as it assumes that changes are being made on adjustment data.
Recordings can only be viewed from the Telemanagement computer.
