STG DRV
Command the fan through the STG network or the local interface. Installed next to the fan or the ventilation box: relay for on/off, 0–10 V output for speed.

How it works
Two command modes, one device.
The DRV is the bridge between the STG network and the ventilation equipment. It sits next to the fan and executes the command, with no dedicated signal cable.
Mode 02
Command over the STG network
Receives commands from the STG network and drives the fan. The MINI or QAI reads the room and sends the command wirelessly; the DRV executes it at the equipment.
STG wireless network
relay · 0–10 V
Several sensors can command the same DRV through the configured rule. Drive selection depends on the motor and the project configuration; the DRV handles single-phase AC or EC fans.
Retrofit with less cablingNo control cable between sensor and fan: less installation time and cost.
Proportional or on/offFine EC fan speed through the 0–10 V output; AC on/off through the 10 A relay.
Independent local operationThe equipment can be operated from the DRV interface even without the network.
Where to use
Main applications.
Car parks
Distributed CO sensors and one DRV on every jet fan or exhaust fan, with a coordinated response.
