Thermostatic Radiator Valves (TR-01) sense the air temperature around them and regulate the flow of water through the radiator which they are fitted to. They do not control the boiler. They should be set at a level that gives you the room temperature you want. These settings may have to be different in each room, and you should set the TRVs to suit each room and then leave them to do their job. Turning a TRV to a higher setting will not make the room heat up any faster. How quickly the room heats up depends on the boiler size and setting, and the radiator size. Turning a TRV to a lower setting will result in the room being controlled at a lower temperature, and saves energy. TRVs need a free flow of air to sense the temperature so they must not be covered by curtains or blocked by furniture.

First we need know what is the radiator Radiators are heat exchangers used to transfer thermal energy from one medium to another for the purpose of cooling and heating. The majority of radiators are constructed to function in cars, buildings, and electronics. A radiator is always a source of heat to its environment, although this may be for either the purpose of heating this environment, or for cooling the fluid or coolant supplied to it, as for automotive engine cooling and HVAC dry cooling towers. Despite the name, most radiators transfer the bulk of their heat via convection instead of thermal radiation   And How does the radiator work? Radiators work through a heat transfer process called convection. When water in the radiator is heated, the surrounding air is also heated up via convection and this hot air is then moved around the room as the air circulates.  Now we basic know what is radiator and how it work,then we must to comprehend how thermostat can do for you?and why choice E-top thermostat 1.     save energy Now due to the problems of the Russian-Ukrainian war, natural gas has become a scarce resource, and many European countries are now switching to electricity for heating. The current mainstream heating is radiator, and the installation of our thermostat valve can effectively save power loss. According to the data from our laboratory and customer feedback, it can basically save about 23% of power every year, which can effectively of saving home energy billsSave money.   2.     Easy install E-TOP, a brand new electric head of TR-01, uses a threaded knob for installation, no drilling or additional tools are required, and it can be installed directly by simply screwing it manually.   3.     Strong compatibility     For a wide variety of radiators on the European market, we have equipped 6 different converter accessories, which can adapt to more than 98% of the radiators on the market and solve the problem of incompatibility.  Winter is coming soon. If you want to replace a brand new energy-saving radiator thermostat for your home, E-TOP's thermostat must be the best choice. In addition to the thermostat radiator valve I mentioned above, we have more products to choose from, such as room thermostat, smart thermostat, heating thermostat, Bacnet thermostat, Air condition thermostat, etc. If you are interested, please feel free to contact me.contact email: info@etopcontrols.com

Apparently, the world is a global village, and people need to communicate, participate in projects and events virtually, and execute tasks remotely. Therefore, there’s a need for internet, multimedia, and most crucial, wireless communication networks. With wireless technologies, people can share data, voice, images, and even videos in a snap. Same for room thermostat, with wireless technology people are easily to set their home climate wherever they are. Especially for NBIOT application, LoraWan is widely used.   There’re several wireless technology that are Frequently used for thermostat control, expect Lora, such as Zigbee Thermostat, Bluetooth Thermostat, WiFI/Zigbee Thermostat and so on. Let’s take a look at the main difference of these wireless smart thermostat, Bluetooth thermostat Bluetooth debate is that both have been key drivers in the IoT world. In fact, each could easily be integrated together for better functionality. While Bluetooth tends to be less battery hungry than Wi-Fi and LTE, it is still more power-hungry than LoRa, except if you are using Bluetooth low-energy. The battery can last at least for 1 year for Bluetooth thermostat. Wi-Fi wireless thermostat Wi-Fi is superior when it comes to bandwidth, it suffers when it comes to battery life and range. Most networks might struggle to work past 15 meters, which makes it unsuitable for scattered IoT devices. In comparison, the low power and long-range nature of LoRa make it ideal for these devices. However, LoRa will struggle to send a single image, let alone large files. It thrives at sending small packets of data, such as temperature and humidity. Zigbee wireless technologies thermostat In the case of Zigbee, each node can communicate with any other node in the mesh network, making it ideal for distant multi-hopping. When used with the right device design, Zigbee can easily rival the power efficiency of LoRa., WiFi and son. Z-wave wireless thermostat Z-Wave and Zigbee are quite similar in that they are both low-power networks that work under a mesh protocol and are meant for short to medium-distance data exchange. On the flip side, LoRa runs under a star network topology, where every node communicates with a specific gateway.  

    Fan Coil Units, consisting of two parts, a fan and a coil, are devices used for heating and cooling. These units need a thermostat to control.E-top FT series room thermostat expertise in controlling fan coil unit system. Features with: Each room can be controlled independently with the fan coil unit. Setting up a zone system is quite easy. 2. You can control them with fan coil thermostats. Thus, in each room, besides meeting the variable load (hotel, hospital) throughout the day, there is also the possibility to choose different room setting temperature. Fan coil systems operate in heating and cooling, it is required to perform heating or cooling in summer or winter periods. This option can be adjusted in the mode section. In General Life fan coil thermostats, heating or cooling mode selection can be made manually. When heating mode selected; If the room temperature falls below the set temperature, the fan coil is activated and tries to heat the environment. In cooling mode, if the room temperature rises above the set temperature, the fan coil is activated and tries to cool the environment. You can customize thermostats to be as: RS-485 Modbus thermostat, 2.4G Tuya WiFi thermostat, 2 pipe system thermostat, 4 pipe system thermostat even can be split room thermostat according to your different necessary.
