b. On Section X6 of the main PCB (see diagram below), connect the digital inputs (DI) as
follows:
3. In order to activate the 0–10 V demand control mode for the external BMS, remove the bridge
between terminals "T/D1" and "T/D2" (X6.5 and X6.6) on section X6 on the AHU Kit's main PCB.
Make sure that all other jumpers remain intact.
4. In 0–10 V demand control mode, in order to achieve the default relation of voltage versus
capacity as shown in step 7, adapt the wiring on the AHU Kit's terminal connectors of section X6
as follows (see also →
Connect the positive pole ("+") to "AI1 (X6.3)" and the negative pole ("–") to "AI2 (X6.4)".
5. Close the AHU Kit enclosure again (see →
p.
40).
