7.3.4 Consideration of the room temperature/room influence
7.3.4.1 Heating circuit room connection
This function determines the enabling of the room sensor in
conjunction with a wall device/room sensor with the direct heating
circuit and all parameters affected by the room temperature
sensing depending on the application.
with the following conditions:
• No room sensor connection with installation of the room
sensor outside the inhabited area (e.g. in unheated rooms like
basements etc.).
• No room sensor connection with multi-family dwellings that
work with different room temperatures based on different
assignments and do not offer a reference room.
• With room connection switched off, the current room
temperature is not displayed in the system information.
• The flow temperature is corrected purely by weather
conditions.
for room influence and connected outside sensor:
• With the room sensor switched on, the heating circuit is
controlled based on the weather taking into account the
current room temperature. The room temperature deviation is
taken into account based on the room factor parameter
setting.
• If SDW 30 wall devices are connected, the actual room
temperature is indicated in the basic display instead of the
heat generator temperature.
• When the actual room temperature drops below the current
setpoint room temperature + 1 K, any active summer switch-
off is disabled, provided automatic operation was not selected.
This setting enables the room temperature-related functions,
while operation via the wall device is disabled.
Public buildings (government, schools, public facilities, etc.)
where only the registration of the room temperature is required.
