In the filed of condensing boiler installation, the term 'Opentherm' is getting more trendy. Why opentherm takes an increasingly important role in a modern underfloor heating system?The following tips will help you understand the basics of Opentherm heating system and opentherm modulating heating control. The opentherm way to control boiler , not cycling your boiler on and off periodically, it adjusts boiler heating water flow temperature precisely. So what benefits can we get if we are using opentherm thermostat?   1. Lower gas fuel bills   As russian-ukraine war, gas fuel price soars by 50% compared to the previous, saving more energy becomes more important mission in the room heating industry. A SmartTherm thermostat utilizes PI algorithm to calculate boiler water set point and adjusts the heating water temperature according to the desired set point. This not only keeps the rooms at the correct temperature, but it also increases the efficiency of the boiler by allowing it to run at lower flow temperatures for a longer period of time. As a result, the boiler stays condensing for longer.   2. Extend boiler lifespan   By allowing boilers to run at a slower rate for an extended period of time, they are less likely to damage the appliance than they would be if they were constantly turning on and off. This means boiler is able to work in optimal performance and reducing more wear and tear.   3. Enhance boiler troubleshooting   ETOP opentherm wifi thermostat offers direct visual displays about the boiler status and error codes, which helps boiler installers and repairers gain more information about the fault reason. Besides the thermostat screen, ETOP thermostat also can do phone app remote checking and remote control. Opentherm provides more advanced boiler monitoring and efficiency control and improvement in the room underfloor heating system and smart thermostat manufacturing technology.  

ETOP HR-02 Wireless 8 Zones Wiring Centre stands out due to its advanced features and flexibility, making it an excellent choice for managing room heating systems, particularly with heat pumps and underfloor heating. Here are some key features. 1. Wireless Communication with Zone Slave Thermostats HR-02 RF wiring centre allows for a completely wireless setup, reducing the complexity for installation. It can communicate with zone slave thermostat without the need for extensive wiring, which simplifies the installation process and enhances aesthetic appeal by minimizing visible cable.   2. Multi-Zone Control The wiring centre can manage up to 8 zones and 16 zones, providing independent temperature control across different zones of a building. The zoning capability is essential for optimizing comfort and energy efficiency, as it allows users to heat only the spaces that are in use.   3. Heating and Cooling Control HR-02-C provides Heat/Cool input to automatic switching between heating and cooling modes, making them versatile for year-round climate control.   4. Valve Type and Delay Time Setting The pump and boiler delay time can set from 0~6 minute by bridge jumper as below picture. The actuator type can choose between NO and NC type as picture.  Please adjust accordingly to needs.  1. WIFI Compatibility Some clients will ask for wifi remote control. Adding a RF gateway, users can make up a intelligent room heating system and achieve remote temperature control on APP.   2. Installation Ease HR-02 wiring centre incorporated clear cable slots that help prevent mixed cables, ensuing organized wiring. In addition, DIN rail mounting helps in maintaining a clean and professional appearance in electrical cabinets.   3. Compact Design With dimensions of 353.5mm x 1184.mm x 59.5mm, ETOP HR-02 wiring centre has a compact design that can be conveniently mounted near the underfloor heating manifold or in other suitable locations without taking up excessive space.
