NOTE: The maximum profile temperature is determined by the respective maximum flow
temperature limit.
After a short power failure of restart, a previously activated screed function is
continued where it was interrupted.
The Screed function parameter is automatically set to OFF when the function is
completed. The screed function can be activated again if necessary.
8.2.2 Assessment of the Room Temperature / Room Influence
8.2.2.1 Heating Circuit with Room influence
Function: This function activates the room sensor of a room device (RS or RFF) which is
assigned to the corresponding heating circuit via the data bus address. The
corresponding room parameters are enabled for operation.
No room sensor in the following situations:
• No room sensor influence when mounting the room units outside the occupied
area (e.g. in unheated rooms like cellars, etc.).
• No room sensor influence in multi family buildings which have different room
temperatures.
• No display of the current room temperature is provided in the system information
if the room influence is off.
• The feed temperature is corrected purely by atmospheric conditions.
Room sensor
enabled
room influence with outside sensor:
• If the room sensor is switched on, the heating circuit is controlled in a weather-
responsive manner on the basis of the current room temperature.
• If an THETA RS room device is connected, the actual room temperature is
indicated in the basic display instead of the heat generator temperature.
• If the actual room temperature drops below the current room setpoint temperature
+ 1 K, any summer deactivation which may be active is cancelled. This is
necessary in order to allow correction of the actual room temperature by the set
room influence.
Room sensor enabled, operation blocked:
With this setting, the functions influenced by the room temperature are enabled,
however, operation via the remote unit is blocked.
Application: Public buildings (offices, schools, etc.) in which only room temperature
monitoring is desired.
