+--- Thread: Heatmiser usage with ucm (/thread-4171.html)
- jmwhooper - 04-01-2015
i have a heatmiser setup with 13 network 12v stats, 2x UH1 and a touchpad controller.
Does the heatmiser touchpad affect the usage of the comfort ucm, or will they work together ok? I\'ve got the heatmiser system hooked up via a rs232 adaptor to my pc and using a serial port monitor there is so much traffic from the touchpad that it\'s hard to see how anything can coexist with it!!
Ultimately my goal would be to replace the heatmiser touchpad and use the comfort ucm to perform the functions instead like setting temps, putting single or groups of stats into setback (frost protection), changing heating timers, boosting the hot water etc. how many of these functions can be performed via the ucm?

We recommend that you use the UCM/Heatmiser with RS485 interface, not ethrnet interface. We cannot control 13 modules with the ethernet interface

Yes that is what I would do Rs-485 all the way.
Will the touchpad be ok with it though, I\'m sure there are some users out there who have the touchpad and ucm

Which touchscpad is that, the wifi one?

It\'s the wired Touchpad TFT model.

Yes you should be able to use this touchpad along with the UCM/Heatmser with RS485
Both act as masters on the bus but there should not be any problem
