ELAUSYS / HAE-805
KNX Heating Actuator Extension 8-Channel
The HAE-805 is an eight-channel heating-valve extension for the MSA-810 KNX master actuator, supporting 24–230 VAC electrothermic actuators at up to 0.5 A per output. It requires an MSA-810 master and is configured through the master’s ETS application.
The product
Designed for your installation.
Eight heating-valve outputs with temperature-control functions
The HAE-805 is an eight-channel heating-valve extension for the MSA-810 KNX master actuator, supporting 24–230 VAC electrothermic actuators at up to 0.5 A per output. Control electrothermic valve actuators on underfloor-heating manifolds, radiators, and compatible heating or cooling circuits. Each channel can follow an external demand or use its own configured temperature-control function.
Control functions and applications
Use a KNX temperature measurement with the built-in controller, or receive an external control demand for PWM or on/off operation. Valve-protection cycles exercise idle valves. Channel short-circuit and mains-failure indications support fault monitoring.
Use one valve-supply voltage per extension. The common supply connection does not allow 24 V and 230 V actuators to be mixed on the same module.
Integrate with the master actuator system
The HAE-805 is an extension of the Elausys Universal KNX Actuator System and cannot operate independently. Its channels appear in the MSA-810 application, using the master’s KNX address.
Plan the module combination in ElauPro. System capacity depends on the extension types and their channel requirements. The combined limit of 40 channels at 10 A applies to MSA-810, SAE-810, and SAE-2410.
Power, installation, and configuration
The master supplies the extension’s control electronics through the side connector. The valve circuits require an external AC supply. Use a suitable transformer for 24 VAC actuators.
Mount the module on a 35 mm DIN rail in the same row as the master and connect it to the extension chain. Generate the system application in ElauPro and configure the channels in ETS5 or ETS6. Configured KNX operation does not require an internet connection.

Frequently Asked Questions
Can this extension operate on its own?
No. It requires an MSA-810 master and is configured within the master’s ETS application. It does not need a separate KNX address.
Do I need a separate room thermostat?
A temperature measurement must be available on KNX. The built-in PI or 2-point controller can use it, or the extension can follow a control demand from an external thermostat.
Can I mix 24 V and 230 V valve actuators?
No. The common supply connection sets one operating voltage for the extension. Use actuators suited to that supply.
Are normally open and normally closed actuators supported?
Yes. Configure the operating direction to match the actuators. Heating/cooling settings and valve limits must also match the application.
What power supply is required?
From MSA-810 through the side connector. External AC supply for valves; a suitable transformer is required for 24 VAC systems.
How is it configured?
Generate the actuator-system application in ElauPro, then configure the channels and group addresses in ETS5 or ETS6. The master and extensions share one KNX address and application.
