I would like to integrate my Mechanical Ventilation Heat Recovery Unit from Paul Lüftung, the type is an Atmos 175 DC. Currently I’m running Openhab 2.3 on a Raspberry Pi (openhabian) with a Zwave wireless network. My main topic is to control the fan level with a zwave dimmer(?), but for me its not clear how I could manage this.
On https://www.pre.ie/Upload/Upload/Manuals/Heat%20Recovery%20Ventilation/Paul%20Atmos%20175%20MVHR%20Operating%20Manual.pdf you will find an operating manual with a coonection scheme.
My questions:
What would be the ideal zwave-dimmer to connect it to the unit?
I doubt you can control this system with a dimmer. There is only one interface to use, and this is 4-wire (Appendix 1, X3).
Which kind of Operating Element is installed?
There is a System-BUS-Switch actuator available (pretty sure this will be expensive ), this would be the best option for complete remote control…
Thank you for your input. In the meantime I contacted the service of the Manufacter. With this actuator the motors of the ventilation can be controlled directly, but then I have to disconnect the control keyboard. I’ll have to think about it.
Can you please explain which system-BUS-switch you mean? I’d consider buying one.
