I have a HWQS system and need to link it to control 16 zone Heatmiser system using 2 x UH-1 and 16 x Slimline-N thermostats. All of the thermostats have external air probes connected.
I use Moxa NPort RS-485 to Ethernet adapter.
I am able to configure and use the system fine when the thermostats are set to take the temperature from in-built sensors. When I switch the thermostats to use the external air probes, all I can get is 12 deg C on in all the rooms. I am still getting a two way comms as I can change the set point via Lutron app and also see it changed when applied via thermostat, so the only thing that does not work is the actual temp reading.
I am using HWQS 9.4.
Has anyone done it and can help please?
