System Components and Airflow
The Systemair FGT022 BASIC is a ventilation unit designed for air handling. The system manages airflow from the outside, through supply and exhaust fans, and includes various sensors and control mechanisms.
Key Components:
- Supply Air Fan (M1): EC-MOTOR, K3G250, 750 W, 3.3 A.
- Exhaust Air Fan (M2): EC-MOTOR, K3G250, 750 W, 3.3 A.
- Outdoor Air Damper (M3): LF 24A.
- Bypass Damper (M5): LM 24A-SR.
- Sensors:
- Outdoor Air Temperature Sensor (B3, B440/PT1000).
- Supply Air Temperature Sensor (B1, TG-KH/PT1000).
- Exhaust Air Temperature Sensor (B2, B440/PT1000).
- Frost Protection Sensor (B6, B440/PT1000).
- Ice Protection Sensor (B5, B440/PT1000).
- Pressure Sensors (Presigo Duo 2500, Presigo 2500A) for supply and exhaust air.
- Control System: Systemair Corrigo S-209464, interfacing via Modbus RS485.
- Electrical Components: Main power connection (230V), transformer (T1, 230/24V 60VA), circuit breakers (e.g., F1, F2, F3), relays (e.g., K1, K2, K3, K4).
- Optional Features: Water Heating (with pump P1, valve V1), Electric Heating, DX Unit (heating/cooling).
The system facilitates air intake from the outside (AUSSENLUFT), supplies conditioned air (ZULUFT), and exhausts air (ABLUFT).
