NOTES
- It will only show
C-Wire
if the thermostat was paired with the hub in repeater mode (i.e. with the C-Wire connected) otherwise it shows the battery level. - To enable repeater mode on CT-xxx/ZTS-500 thermostats, exclude the thermostat, connect the C-Wire and then pair the thermostat with the hub
- The DTH automatically detects the available features on the thermostat and enables the appropriate tiles (otherwise itāll show a blank).
- To enable detection of Aux/Emergency/Multi stage heating for NON CT-xxx/ZTS-xxx thermostats (e.g. GoControl, Trane, MCO, Honeywell etc), enable the option in the device preferences page (disabled by default since most thermostats do not report it correctly)
- If have a C-Wire with battery backup, enable the setting to report battery with C-Wire connected
How to soft reset CT-xxx thermostats (i.e. reconnect with the controller)
Open the thermostat top cover and there is a reset button. Press it for 1 seconds. Now open the ST app and click on the refresh tile to resync all the settings.
