9 Heating circuit control

The heating circuit can be configured to any type of module. If the RMZ782B is re-
placed by some other module, all settings using type reference RMZ782B… via “Extra
configuration“ must be reconfigured.
Function blocks can always be activated via “Extra configuration“, independent of the
type of plant. A function block is activated by assigning an output to a terminal. Here,
the heating circuit can be configured to any terminals that are free. If all outputs of the
heating circuit are set invalid, the heating circuit will be deactivated.
For weather-compensated heating circuit control, the outside temperature is required. It
can be configured as follows:
•
For heating circuit 1, on the following menu:
Main menu > Commissioning > Extra configuration > Miscellaneous > Inputs > Outside sensor
•
For the 2 other heating circuits, on the following menu:
Main menu > Commissioning > Extra configuration > Heating circuit 2
(or
3
)
> Inputs > Outside
sensor
The outside temperature can also be transmitted via the Konnex bus.
In addition, a solar intensity sensor and wind speed sensor for common usage by all
heating circuits can be configured on the following menu:
Main menu > Commissioning > Extra configuration > Miscellaneous > Inputs
The impact on the
individual heating circuits can be parameterized.
For more detailed information, refer to section 14.6 “Weather data”.

* Outside sensor:
Only heating circuits 2 and 3 have their own outside temperature. Heating circuit 1 shares the outside tem-
perature with other function blocks in the controller. The outside sensor is to be configured under
