HVAC Ventilation & Air Handling Integration
KNX integration with HRV units, VAV boxes, and AHUs — Systemair SAVE Modbus RTU register maps, TROX TVZ VAV BACnet/IP to KNX via LOYTEC bridge, demand-controlled ventilation with CO2 sensors, and supply air temperature optimisation for energy efficiency.
Systemair SAVE HRV Integration with KNX via Modbus RTU
Integrating Systemair SAVE VTC 700 M and SAVE VSR 300 HRV units with KNX via Modbus RTU — RS485 wiring and baud rate settings, full register map (4001-4016), MDT Modbus Gateway poll group configuration, KNX group addresses for supply air temperature and boost enable, and CO2-triggered boost logic.
TROX TVZ VAV Box BACnet/IP to KNX via LOYTEC LGATE-950
Mapping TROX TVZ-D VAV volume flow controllers to KNX via LOYTEC LGATE-950 BACnet/KNX router — BACnet MS/TP device configuration, LGATE web UI mapping (actual flow, damper position, room temp), zone control sequence, multi-zone scaling for 100-device buildings, and BACnet COV for traffic reduction.
Demand-Controlled Ventilation with KNX CO2 Sensors: IAQ and Energy Savings
Implementing demand-controlled ventilation (DCV) with KNX CO2 sensors — Elsner KNX CO2-T-UP, Thermokon SR04, and Zennio ZYCT-CO2 sensor comparison, DCV threshold logic (400-1400 ppm), ETS6 logic block configuration, EN 13779 IDA category targets, night purge sequence, and BREEAM Hea 02 compliance.
