Heatmiser UCM

OK, thanks. I will contact heatmiser for details.

The heatmiser modbus protocol is download able from here:

That is good. That means that you can use UCM/Modus-485 to control the Edge series

Just a little confused. You say - The wifi thermostats have been discontinued and are replaced by models which are not compatible with comfort. Yet the manual  still refers to the wifi and having the sub module option for ETH03.  Also the ETH03 sub module is still referenced as an accessory for the UCM/Heatmiser  on the the Cytec web site. Am I right in thinking all of the references to WiFi are no longer relevant to UCM/Heatmiser and that only RS485 connections are possible?

I might be wrong here, but I think the previous WiFi controllable variants aren\'t available now.

Heatmiser now need you to have a neohub to control from their app, or use modbus. I\'ve not figured out any other way, but I am no expert, just trying to update ours too.

Thats right, the wifi thermostats that could be controlled by ucm/heatmiser with eth03 have been discontinued so that is no longer an option, so that was a waste of time to develop
We will have to amend the manual.
