The device has potential-free output connection points, so in normal case the 230 V does not appear on its output, only the 2 attached wires are connected or disconnected from each other when the thermostat switches. If you wish to have the 230 V on the output when the thermostat switches then you should connect the phase wire to the NO of COM connection point so the thermostat according to the manual instruction. Before you connect the phase wire, make sure that it is disconnected from the electric power supply. The device must be installed and connected by a qualified professional.

If the appliance cannot be controlled via the Internet because the application indicates that the appliance is inaccessible and does not respond to the modifications then the connection between the appliance and the web interface has been interrupted. This situation may be due to several reasons. The problem is most probably caused by the Wi-Fi router being used. It is expedient to restart the routers from time to time by interrupting and restoring power supply. In most of the cases this type of problems is solved by restarting the router. If the appliance is still inaccessible at the front end after a few minutes have elapsed then it is recommended that the appliance is reconnected to the Wi-Fi network according to the Instruction Manual. If the connection is successful but the appliance is still inaccessible then it is recommended that the router is set to factory default, because it may occur that the device cannot be connected to the Internet because of some settings. 

After the power supply is restored the appliance continues to function according to the settings defined before the power outage (or according to a preset program in programmable mode).
