Device safety
Among other aspects, the safety of devices is ensured by extra low-voltage power supply (AC 24 V) as per SELV or PELV.
Electrical parallel connection
Electrical parallel connection of VAV Compact Controllers, provided the required operating voltage tolerance is observed. The voltage drops of the supply lines must be taken into consideration.
BACnet MS/TP wiring
When planning and installing room controllers and field devices with BACnet MS/TP connection, the permissible cable lengths, power supply and topologies have to be followed. Planning should take into account possible future extensions of a plant.
Note
Mechanical coupling of the devices is not permitted.
Warning, maintenance
Do not open the actuator!
The device is maintenance-free. Only the manufacturer may carry out any repair work.
