Nibe S1156 - Selectable Inputs and Outputs; Selectable Input Configuration; Selectable Output Functionality; myUplink Network Connection

If several accessories are to be connected, or are already
installed, the boards are connected in series.
Because there can be different connections for accessories
with accessory board (AA5), you should always read the in-
structions in the manual for the accessory that is to be in-
stalled.

2. Follow the flow meter’s cable out at the rear.
SELECTABLE OUTPUTS/INPUTS
S1156 has software-controlled AUX inputs and outputs for
connecting the external switch function (contact has to be
potential-free) or sensor.
In menu 7.4 - "Selectable in/outputs", you select the AUX
connection to which each function has been connected.
For certain functions, accessories may be required.
TIP
Some of the following functions can also be activ-
ated and scheduled via menu settings.
Selectable inputs
Selectable inputs on the base board (AA2) for these func-
tions are AA2-X28:3-11. Each function connects to any input
and GND (AA2-X29).
