Nowadays, home type water heat pump system normally works without fan coil. This heat pump has summer mode (cooling) and winter mode (heating). In the heat pump control system, there is one thermo sensor connected. This sensor connected to main controller. If outside temperature more than 25-degree, system has signal pulse from the thermo sensor to switch heat pump to summer (cooling) mode. If outside temperature lower than 15-degree, system has signal pulse from the thermo sensor to switch heat pump to winter (summer) mode.  Those modes switch automatically done by heat pump control system. There is no relationship with thermostat.   However, to keep connected thermostats work in the same mode as water heat pump is extremely important and meaningful. Our thermostat system should work reversely in different mode. Winter time we should set higher degree of the room to make the room hotter. Summer time we should set the degree lower to make the room cooler.  Therefore, in the thermostat, there should be CO input contact. This contact is “Normally Open Contact”, dry contact. When the 230/24V signal pulse comes from the heat pump, base unit will switch to summer mode (cooling), and send this 230V/24V signal pulse to connected thermostats. When all thermostats get this 230V/24V signal pulse from wiring cetnre, all room thermostats will switch to the summer mode (cooling). If the room temperature higher than thermostat value, thermostat let the actuator open and let the cool water inside into room pipe system.   If there is no signal from heat pump to CO contact at wired 8 zone wiring centre, thermostats should work in winter mode (heating). At that time, if room temperature colder than thermostat value, digital programmable thermostats should let the valve open and let the hot water inside into room pipe system.     Xiamen E-Top Controls as professional ODM thermostat suppliers, we provide both 8 zones wired wiring centre and digital smart WiFi thermostats.   For detail information, please contact with us from info@etopcontrols.com

With the improvement of people's living standards, everyone's awareness of enjoyment is gradually strengthened. Especially in winter and summer, when the house temperature is very high or very low, we will install some heating or cooling equipment, for example, central air conditioning, for this central air conditioning, we need to install a controller in the room to further control the temperature, this is room thermostat.    How should we set and control the room thermostat? Simple mechanical room thermostats with sylphon, with remark anti-frost, 5C--10C--15C--20C--25C--30C, are easy to operate, choose a certain tempearature just as the air conditioner, the room will keep this temperature. LCD programmable room thermostats: 7 days 4 programmable room thermostats. According to your living habits for one week. You can pre-program it for turn on, turn off, raising temperature, constant temperature, etc. For example, as soon as you go to work in the morning, the wall boiler will shut down by itself, you get home at six o 'clock in the afternoon, the boiler will start to run by itself at 5:40, when you walk into the house, it is already 25C room temperature. When you fall asleep, the room temperature automatically jumps to 20C. All these changes are happened due to your presetting. We E-top has been engaged in room thermostat OEM/ODM service since 2009 and we have develop many many room thermostats. Recently, we E-top has sucessfully developped E-ink Lithium Battery Thermostat WT-75:

Electric baseboard heaters are good for areas of your house that central HVAC does not reach. If you are going to installer a baseboard heater, make the thermostat setup the best you can by separating it from the heater body. This provides more accurate temperature gauging, plus it makes it easier for users to access the thermostat. You can install a thermostat on the baseboard heater rather than install a thermostat on the wall. This type of installation is easiest since it does not involve opening up walls, it is considered to be inferior to installing the thermostat on the wall. However the room temperature sensing is not as accurate as the wall thermostat. Plus that,baseboard heater-mounted thermostats also entail bending down every time you want to change the temperature. Wall-mounted thermostats are easy to access. If you have your walls open and no drywall has yet been installed, it is highly recommended that you install a wall line voltage thermostat.    What Is a Line Voltage Thermostat?   Line voltage thermostats are simple mechanical devices that connect and disconnect the power going to your heater. These thermostats act much like a valve to control the water pipe. When the valve is open, water flows. When the valve is closed, water stops. Line voltage thermostats mechanically interfere with the flow of electricity from the power lines to the baseboard heater. When there is no connection in the device, the heater cannot turn on. When the connection is restored, the heater can activate.   Line voltage thermostats have a basic temperature-sensing device so that they turn on or off according to a temperature range you have set. They are cost-effective and easy to install, but you especially need to make sure you've got the wiring correct. Parameters of E-Top’s baseboard heating thermostat:

With the rapid development of science and technology, the field of smart home has ushered in many technological innovations. Among them, the OT protocol (OpenTherm), as an open communication standard, has become a popular protocol in the European market. The OT protocol supports two-way communication between thermostats and boilers, can send simple temperature setting instructions, and can also obtain boiler status information in real time. This intelligent adjustment capability greatly improves the accuracy and energy saving effect of the thermostat, making the thermostat reach a new height in comfort and energy management.   The core advantage of the OT protocol lies in its compatibility and openness. Equipment from different manufacturers can be interconnected through the OT protocol, and users can freely choose the combination of thermostats and boilers according to their needs without being limited to the same brand. This flexibility has made the OT protocol quickly become the first choice for high-efficiency temperature control systems worldwide.   WT-11 OT protocol WIFI thermostat: the best choice for intelligent control With the support of the OT protocol, our company launched the WT-11 OT protocol WIFI thermostat. This thermostat not only fully supports the OT protocol, but also integrates advanced WIFI control functions, further improving the user's operating experience and the intelligence level of the device.   The WT-11 OT protocol WIFI thermostat is a high-performance thermostat designed for modern smart homes. It is fully compatible with the OT protocol and can communicate bidirectionally with boilers that support the protocol to monitor and adjust the indoor temperature in real time. Through this intelligent adjustment, the thermostat can achieve efficient use of energy while ensuring comfort.   Another highlight of this thermostat is the WIFI control function. Users can remotely control the thermostat anytime and anywhere through the smartphone APP to view and adjust the indoor temperature and boiler hot water supply status. In addition, when the boiler fails, users can view detailed diagnostic information through the APP and share this information remotely with maintenance personnel for quick troubleshooting. Product Features a.Intelligent adjustment that supports OT protocol As a thermostat that complies with the OT protocol standard, the WT-11 is capable of comprehensive bidirectional communication with the boiler. This means that the thermostat can not only adjust the indoor temperature, but also receive real-time feedback information from the boiler, including system status, operating mode, and fault codes. Through this intelligent communication, the thermostat can control the indoor temperature more accurately and reduce energy waste.   b.Remote WIFI control The WT-11 programmable thermostat supports WIFI function, and users can easily achieve remote control through the "Smart Life" APP. No matter where the user is, they can check and adjust the temperature settings at home at any time to ensure that the indoor environment is always in an ideal state. Remote control also helps users better manage energy consumption and save money.   c.Window detection function This smart thermostat also has an intelligent window detection function. When it detects that the indoor temperature drops rapidly in a short period of time (such as doors and windows suddenly opened), the intelligent thermostat will automatically suspend heating to prevent unnecessary energy consumption. This function not only improves the intelligence of the system, but also simplifies the user's operation and reduces the frequency of manual adjustments.   d.User-friendly programming and settings The WT-11 thermostat is equipped with an intuitive user interface and supports programming settings in multiple modes. Users can preset temperature control plans according to different time periods and living habits, whether on weekdays or weekends, they can enjoy the comfortable experience brought by intelligent temperature control.   e.Comprehensive fault diagnosis and maintenance support Through tight integration with OT protocols, the WT-11 thermostat can provide up to 127 fault diagnosis information. Users can obtain detailed boiler fault data remotely through the APP without having to visit the site in person, and share this information with professional maintenance personnel, greatly simplifying the troubleshooting process. The launch of the WT-11 OT protocol WIFI thermostat is an important innovation in the field of smart home. With the promotion of the OT protocol worldwide, we believe that this thermostat will become a star product in the market. Its intelligent adjustment and remote control functions are exactly what modern consumers urgently need for smart home products.
