Control
c. On the terminal connector of Section C, located on the upper mounting board inside the
AHU Kit enclosure (see diagram below), connect the digital inputs (DI) as follows:
● Heating start to COM and DI1
● Cooling start to COM and DI2
● Fan mode (free cooling) start to COM and DI3
● All DI contacts open = Stop
3. In order to activate the 0–10 V demand control mode for the external BMS, remove the jum-
per (JP1) between terminals “M2-5” and “M2-6 (FREE)” on the AHU kit’s terminal connector
of section F. Make sure that all other jumpers remain intact.
4. For advanced version only:
On the AHU kit’s terminal connector of section F, disconnect the white wire from terminal
“M2-1” and the red wire from terminal “M2-2”.
For medium version: Proceed with step 5.
5. In 0–10 V demand control mode, in order to achieve the default relation of voltage versus ca-
pacity as shown in step 7, adapt the wiring on the AHU Kit’s terminal connector of section F
as follows (see also “5.4 Terminal board layout”).
For advanced version: Remove the jumpers from M2-1, M2-2 to M2-3 and M2-4 and connect
the positive pole (“+”) to “M2-3” and the negative pole (“–”) to “M2-4”.
For medium version: Connect the positive pole (“+”) to “M2-3” and the negative pole (“–”) to
“M2-4”.
6. Close the AHU Kit enclosure again (see “4.1 Installation of AHU Kit“ – step 5).
7. Via the signal wiring from the external BMS, select the 0–10 V demand control functionality
as follows:

1 No cut/Stop: AHU system / indoor unit is completely switched off.
2 No Limit: No restrictions applied by BMS to AHU system / indoor unit performance (equivalent to “full-load operation“ of AHU system / indoor unit).
Note:
The control system is based on the rule that the last command within a sequence always
takes precedence over the previous commands. In order to avoid unexpected control behavi-
our in a system where both 0-10 V demand control signals and digital input signals are being
used, it is very important to ensure that the DI signals are applied BEFORE applying the
demand control signals.
