- Go to “insert mode” by pressing “+” button in VERA for 2 seconds, or by using the function in the web interface in “Devices” and there select “Add Device” (the orange LED flashes slowly in the Z-Wave Gateway Vera controller).
- Enable DIP switch 1 of SRT321 thermostat (ON).
- Spin the wheel of SRT321 up till displaying “L” on the screen.
- Press the wheel to include the device. The “L” flashes and changes to “LP” and you will see the VERA thermostat on web console interface.
- Stop “insert mode” in VERA by clicking on the blue “Refresh” button on the top right. Now you will see the message “Unit busy” in the web console interface for a little while.
- After Vera has completed the initial configuration, the thermostat device appear on the console . It will be marked with the message: “Wakeup to configure”, in red.
- Spin the wheel to the letter “n” and press the wheel. This adjusts the room temperature and the warning message disappears.
- Replace the DIP switch # 1 in the normal mode (OFF), remove the battery for 5 seconds and re-insert.
Now you can adjust the temperature of the device in VERA web interface and it will be displayed on the LCD screen of the thermostat. The temperatur update can take up to 30 minutes (1,800 seconds), it might be seem as a mistake, but this is a delayed response that preserves battery life. This period can be set in the configuration window in the “clock interval (seconds):” between 256 (minimun) and 1,800 seconds. A good balance would be 600 secs (10 minutes).
It is possible now also to locally change the temperature by turning the thermostat dial. The configuration and the change will be displayed in the VERA web interface.
After you include the thermostat in Vera, you will have to change some configuration settings in order to make it work properly in the network and report the temperature to Vera. By default Secure Thermostat is set to not do this automatically (see configuration parameter 1 below) so you have to add this parameter yourself and insert a value between 128 – 255. To add a new configuration parameter, you have to click on the little wrench on the Dashboard, go to Device Options and click on ‘Add configuration settings’, then fill in the values for Parameter 1 as below in the pictures.
The unit supports 3 single byte configurations for the temperature sensor functionality of the unit in the range 1 – 3 respectively.
- Configuration Parameter Number 1:0–127 disables temperature sensor, 128-255 enables temperature sensor. Default = 0.
- Configuration Parameter Number 2:0-127 = Celsius, 128-255 = Fahrenheit. Default = 0.
- Configuration Parameter Number 3: 1 – 100 = Delta T in steps of 0.1 degree. Default = 10 (1.0).
Note: sometimes in Windows 7, when you run the command from the computer to the thermostat, the temperature is set to 0. we think it’s a problem with the operating system because Windows XP and MAC works correctly.
