Where to locate the temperature sensor and the main unit?
It is expedient to locate the temperature sensor where you stay regularly or a long period of time so that the sensor is oriented in the direction of the natural ventilation of the room but is not exposed to draught or extreme heat (e.g. sunlight, refrigerator, chimney, etc.). Its optimal location is at a height of 1.5 m from the floor level.
When choosing the location of the main unit you should remember that bulky metal objects (e.g. a boiler, buffer tank, etc.) and metal building structures may have an adverse effect on propagation of radio waves. If it is possible, in order to ensure trouble-free RF connection, we recommend that you install the main unit at a height of 1.5 to 2 m and at a distance of 1 to 2 m from the boiler or other bulky metal constructions. We recommend that you check reliability of Wi-Fi connection at the place selected before installing the main unit. Do not install the main unit under the housing of the boiler or near hot pipes because it may damage the parts of the device or compromise Wi-Fi connection. We also recommend that the power is preferably supplied to the main unit from a socket other than that of the boiler (and from another phase, if it is possible), and line power must not be supplied to the main unit from the boiler on any account. To avoid electric shock, entrust a specialist with connecting the main unit to the boiler!
Can more than one temperature sensor be connected to a single appliance?
Yes, you can connect several wired temperature sensors simultaneously to a single appliance according to the Instruction Manual, but you can control the heating process only by one of the sensors, while the other sensors can only be used to provide information.
What should do if the thermostat switches but the 230 V does not appear on the output?
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.
What should you do if the signal of your Wi-Fi router is weak and thus B300 is outside the range of the router?
If it is possible, put the router closer to your B300 appliance. Another option is to place a Wi-Fi signal booster between the router and B300 to extend the range of the router.
What should you do if you encounter a problem related to the Wi-Fi network?
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 Chapter 4.5 of 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. While the thermostat is inaccessible via the Internet you can manually turn it On/Off according to the Subchapter 7. e) of the manual.
