KNX climate control connects room temperature sensors and thermostats with heating, cooling and ventilation: valve actuators for underfloor heating and radiators, fan coil actuators, and gateways to VRF and split air conditioners. Each room can follow its own setpoints, schedules and presence.
Compare outputs, valve types and supported air-conditioning systems, then add the devices to the project planner.
Frequently asked questions
Can KNX control VRF or split air conditioners?
Yes, through a KNX gateway for the air-conditioning manufacturer's system. Check that the gateway supports the exact indoor unit model.
What is a fan coil actuator?
A KNX actuator that switches the fan speeds and controls the heating and cooling valves of a fan coil unit, usually from a room thermostat on the bus.
How does presence detection save energy?
A KNX presence detector tells the climate controller when a room is empty, so it moves to an economy setpoint and returns to comfort when someone comes in.
