This application connects to a CT425-BT temperature controller using Bluetooth Low Energy. From it, you can monitor real-time temperature readings and the device's output status. You can also change the setpoints for each output.
Instructions: With Bluetooth powered on, open up the application and scan for devices by selecting Scan on the top right. Bluetooth Low Energy (BLE) devices in range will be populated in a table which can be accessed by three vertical dots that appear next to the scan button (if the three dots do not appear, no devices have been found). Tap the name of the CT425-BT device to connect to it.
Wait for several seconds as the phone attempts to connect to the CT425-BT. When a device is properly connected, “Scan” will change to “Disconnect” and temperatures will appear. To change units and setpoints, select the Settings button and change the appropriate settings. The CT425-BT is updated when the Save button is selected. Then use the back key to return to the previous screen.
When finished, disconnect the CT425-BT by selecting Disconnect and then closing the application.
