KNX DIN Heating Actuator 8 In / 8 Out
Art. No.: HA08A01KNX
This KNX DIN rail heating actuator is designed for the control of electrothermal valves in heating and cooling systems. The device features 8 triac outputs and 8 freely configurable inputs and is suitable for professional HVAC applications within KNX installations in residential and commercial buildings.
The outputs can be individually configured as 8 channels for on/off control or PWM control, or as 4 channels for 3-point valve control. This makes the actuator highly versatile for applications such as underfloor heating, radiators, fan coil systems (2- and 4-pipe) and zone heating.
The 8 inputs are intended for potential-free contacts and can be used for switches, push-buttons, scenes, shutter and blind control, sequences and step commands. In addition, inputs 1 to 4 can be configured as outputs for signalling LEDs or as analogue inputs for NTC temperature sensors.
The actuator provides extensive integrated thermostat functionality. A total of 8 thermostat modules are available, with each module managing 2 control stages using an integrated PI controller. This enables precise control of heating and cooling systems, valves and fan coils.
Furthermore, 8 logic blocks are available to implement simple logical functions or more complex calculations using algebraic and conditional operators. Predefined algorithms are also available, such as proportional temperature and humidity control and dew point calculation.

Important note
The maximum number of electrothermal valves per output depends on the inrush current of the valves used. Never exceed a total inrush current of 4 A per group of 4 outputs. The use of an activation delay between multiple outputs is recommended to reduce current peaks.
The device is intended for indoor use only and must be installed in low-voltage distribution boards in accordance with applicable KNX and safety standards.
