COMPUTHERM B300 type switching-mode room thermostat is able to control vast majority of the boilers and air-conditioning equipment available on the Hungarian market. It can be easily connected to any gas boiler or air-conditioning equipment which has a two-wire room thermostat connection point, irrespective of whether it has a 24 V or 230 V control circuit. In addition, the thermostat is also suitable  for  controlling  electrical  and  electronic  devices  which  can  be  turned  on  and  off  by interrupting and resuming power supply.

Owing to its characteristics, B300 is most suitable for controlling heating systems but it can also be used to control air-conditioning equipment. For controlling a cooling system the working mode of the thermostat should be changed in its settings.

No, the appliance is able to control air-conditioning equipment and any other device which can be operated only by its ON/OFF function. In the settings menu it is possible to switch between the different working modes.

No. Each thermostat is connected to the local Wi-Fi network separately and this solution guarantees reliable and trouble-free operation of the appliances.

To install and modify the settings it is necessary to have a Wi-Fi network with Internet. After that the thermostat can work without Wi-Fi connection according to its settings. While the thermostat is inaccessible via the Internet, you can manually turn on and off it with a button located on the side of the appliance as described in Subchapter 7. e) of the Instruction Manual. Even so to use the thermostat comfortable it is recommended to connect the thermostat to a stable Wi-Fi network with Internet.

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!

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.

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 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.

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).

Press and hold the button located on the side of the product for 3 seconds.  Following this, release the button for 1 second then press again and hold it down for 3 seconds.  Now you can release the button and the product is set back to factory default setting.
