Features
- ACB (Advanced Communication Bus) bus
interface with ModBus protocol for the connection
to compatible D+H control panels or direct
integration into building management systems,
for example
- BSY+ electronics for reliable and accurate
synchronous operation of up to 8 drives
- Individually programmable via software SCS
- Outstanding quiet performance thanks to
acoustic decoupling of the drive components and
reduced motor speed in ventilation mode
- SHEV-high speed function (fast-running feature
in case of an alarm)
- Protection system for the main closing edge
- Rated voltage and Bus-signals loopable for max.
3 drives
- Connection possible from both sides
- Relief of pressure on window gasket after closing
- Direct connection of additional closing edge
protection at the drive possible (SKS option)

Scope of supply
Drive unit with 2.5 m silicone cable and cover caps.
Depending on the type of window, different bracket
sets are available separately.
! IMPORTANT ! Safety Notes
1. Mounting of the drive should be carried out by a D+H distributor, whose qualification and experience is
ensured by regular in-house training.
2. All wiring must be installed by a qualified electrican according to National Electrical Codes, NFPA 70.
3. For indoor use only. Use always rain detector with danger of rain (e.g. at domelights or roof windows).
4. Observe enclosed red safety slip!
5. Danger of violent pressure in handaccessible area.
6. The window operators have been evaluated for Residential or Light Duty Commercial Use only.
7. A suitable field wiring means should be provided in the end use application.
8. The mounting and routing of external wiring should be determined in the end product.
9. The mounting of each unit shall be evaluated in the end use.
10. The suitability of the leads for field wiring should be determined in the end-use application.
11. The drive must be mounted a min of 8 feet above the floor or any access level.
12. The drives were not evaluated for entrapment protection since they are to be installed at least 8 feet above
the floor. Where entrapment is a consideration, the need for additional tests and evaluation should be
determined during the end product investigation.
13. The drive shall be connected to a Class 2 power supply.
For North America:
14. The Uniform Building Code Standard Vols. 1, 2 & 3 have to be observed.
