BOOST TIMER
Operation

NEGATIVE PRESSURE
COMPENSATION
Operation
When you enable the ILMO cooker hood boost timer, the ventilation unit compensates the negative pressure the cooker hood generates
during the boost period. The function requires an ILMO cooker hood model that has a microswitch and a boost damper. Use the Premium
panel for enabling the function from the menu
Installation and service/Functions/Negative pressure compensation.
The code for access to the Installation and service menu is 1234.
DDC CONTROL
8: 0 V (GND)
7: Temperature signal for supply air 0–10 VDC
6: Fan speed signal 0–10 VDC
5: Temperature reference for supply air 0–10 VDC
4: Fan speed reference 0–10 VDC
3: Group alarm – signal from the ventilation unit (earthed contact)
2: Emergency stop (if contact between terminals 1–2 is broken,
the ventilation unit will stop).
1: 0 V (GND)
FAN SPEEDS WITH THE AC VENTILATION UNIT:
Fan speed 1 = 1.0–2.9 VDC
Fan speed 2 = 3.0–4.9 VDC
Fan speed 3 = 5.0–6.9 VDC
Fan speed 4 = 7.0–8.9 VDC
Fan speed 5 = 9.0–10.0 VDC
