Start from what you need to do.

The STG MINI reads temperature, humidity, CO and CO₂ and shows everything on the interface, without driving any equipment.

Two ways: direct actuation by the QAI (measures and drives in the same device) or a MINI sensor with a remote DRV at the fan.

The STG CPD measures differential pressure with its built-in sensor and modulates the fan continuously. It is the stairwell pressurisation controller.

With the equipment's K-factor configured, the CPD calculates airflow from pressure and holds the desired value. Applies to ventilation boxes and fresh air systems.

Two digital inputs of the CPD each receive an external pressure switch from one filter. Each filter's status is identified separately.

The STG DRV switches or adjusts the speed of single-phase AC and EC fans, through its own interface or the STG network. For three-phase motors, a variable frequency drive.

The STG AHU set (room module + machine module) or the complete panel already assembled with the peripherals.
