Heating Systems & KNX
Gas boiler and condensing boiler KNX integration via Modbus TCP for setpoint and fault monitoring, heat pump SG Ready and Modbus integration for PV self-consumption optimisation, and underfloor heating zone control with KNX electrothermal actuators and PI room thermostats.
Gas boiler KNX integration: Viessmann Vitodens and Vaillant ecoTEC Modbus setup
Viessmann Vitodens 200-W ViCARE ModBus module wiring and Modbus TCP register map for flow setpoint, return temperature and fault codes. Vaillant ecoTEC eBUS and OpenTherm alternatives, cascade boiler lead/lag control, DHW scheduling and fault alerting to ARISTO BMS via KNX group addresses.
Heat pump KNX and SG Ready: Vitocal, Aquarea and arotherm plus self-consumption control
SG Ready 4-state standard wiring to KNX binary output relays for Vitocal and arotherm plus. Panasonic Aquarea CZ-CAPRA1 native KNX SG Ready group object. Modbus TCP registers for variable setpoint COP optimisation and buffer tank control to prevent short-cycling.
Underfloor heating KNX zone control: electrothermal actuators, manifold wiring and PI control
Danfoss TWA-A 230V NC electrothermal actuator wiring to MDT relay actuator channels, Belimo TR24A-SR modulating valve 0-10V control, ETS6 PI thermostat parameters for UFH, manifold pump run-on logic and floor sensor overtemperature limit per EN 1264-2.
