Among E-top room thermostats, there is a kind of thermostat or timer with 'volt-free contacts', or 'volt-free switching', operates a switch that opens and closes its contacts, but no voltage or current will flow. Volt-free room thermostat for, such as, boiler heating system do not need to provide power source to boiler. All E-top thermostats are CE certificated room thermostats. Depends your requirements, E-top Controls provide you multiple choice for different configuration: Child lock room thermostat-prevent children unconsciously operate, Open window detection thermostat-turn off heating/cooling system if door or window opened to save energy, Smart room thermostats can be controlled on smart phone via Tuya Smart Life APP remotely or other protocol you needs.    

  With the energy crisis gradually intensifying, air source heat pump attracts much human attention. E-Top is also committed to the research and development of air source heat pump temperature controllers/Room Thermostats   A heat pump thermostat's basic function is based around the temperature, when the temperature indoor falls below the set number, thermostats will know to turn the heat pump on. The heat pump is switched off once the set temperature is reached.   There are three types of thermostat suitable for air source heat pump : mechanical thermostat, electrical thermostat, and smart thermostat.   Mechanical thermostats are the least expensive of the three, like a standard manual thermostat they are basic in terms of function, allowing you to turn your heat pump on or off. Electrical thermostats can be programmed with details like date and time, and whether you’d prefer manual or automatic functioning. Smart thermostats can do all the above, whilst allowing you to connect wirelessly via your phone or smart device. You can use an app to operate and schedule your smart thermostat.   Smart heat pump thermostats make sure that there is sufficient heating/cooling inside house at all times. We have WiFi and zigbee Smart thermostat for selection, for more information, pls. contact info@etopcontrols.com

  Generally, we use on/off type thermostat to control the boiler, the sensor built into the thermostat detects the temperature in the room and judges the boiler switch according to the comparison with the setpoint.   Opentherm,It is a communication name that links HVAC (heating and cooling equipment) and room thermostats beyond the manufacturer's control system, it consists of communication protocols and port specifications, and represents a technical system that can achieve high functionality and future expansion possibilities using common simple installation methods. • Set and read tap water temperature • Turn tap water on and off • Read the outdoor temperature • Read failures • Weather related controls Opentherm make your thermostat as simple as plug-and-play!   Currently, E-top has joined the OT association,and have finish the development of OT thermostats base on the OT protocol, and OEM for several local boiler manufacturers, and of course, WIFI function was combined.   Make OT thermostats a part of your smart home!  

  The thermostat for an air to water heat pump functions similarly to a traditional thermostat, but with some additional features specific to heat pump systems. Air to water heat pump thermostat allows you to control the temperature of your home by activating or deactivating the heat pump's operation.   Here are some key features you might find on an air to water heat pump thermostat:   Remote control: You can control the underfloor heating and cooling thermostat and adjust temperature settings remotely through a smartphone app.   Temperature setting: You can set the desired temperature for your home using the digital HVAC thermostat. The heat pump will work to maintain this temperature.   Mode selection: The wired or wireless heat pump thermostat usually offers different modes, such as heating, cooling, and auto. In heating mode, the heat pump will provide warmth to your home. In cooling mode, it will help to cool your home. The auto mode allows the thermostat to switch between heating and cooling as needed.    Fan control: Many programmable heat pump  thermostats have fan control options, allowing you to adjust the fan's speed or set it to automatic mode. Such fan coil unit normally install at ceiling for heating or cooling.  Programmable settings: Some room thermostats offer programmable settings, which allow you to set different temperatures for different times of the day or week. This can help optimize energy efficiency and comfort.   E-top release a full range of air to water heat pump thermostat a.    Battery wired heat pump thermostat:   HT-02/HT-11/HT-15/HT-20/HT-25   a.    Battery wireless heating and cooling thermostat: WT-02/WT-08/WT-11/WT-20/WT-25  a.    Smart Life wireless heat pump thermostat as WT-20 WIFI/WT-25 WIFI    a.    2 stage heating UFH & Fan coil thermostat as FT-66     For more information, please email to info@etopcontrols.com for details.   

Hereby, share the three main roles of the different pressure bypass according to E-top OEM room thermostats in different system:   1st:  Protect the end control valve of the heating system to prevent the pressure difference between the two ends control valve from being too much. In normal heating system end control valve: one is floor heating’s manifold electric heating valve, the other one is thermostatic radiator valve (TRV). Both of their close pressure difference is about 10m, if the pressure difference too large, the valve can not close. But in daily use, if pressure difference is over 3m, means 30KPa, there will be noise in the control valve. So we just need to prevent the noise of the control valve, it will be easy to solve the problem of the close pressure difference.   2nd:  Protect the mainframe to prevent the mainframe flow from being too small. For air source heat pump (thermostat), if mainframe flow is too small, there will be a warm causing mainframe stop working. For boiler system (thermostat), if mainframe flow is too small, it will make boiler On/Off frequently, even overheat protection then turn off the boiler.   3rd:  Protect water pump (thermostat) to prevent pump head too large due to the small flow. For water pump in the system, including build-in and out pump, if flow is too small, it will cause the pump head too large. At this time, water pump will deviate significantly from the ideal working state point, increase energy consumption and motor overheat.   These three roles work when the system is under partial load, that is, when part of the end is closed. Depending on the system, sometimes three roles work at the same time, sometimes only one or two of them work(s).

The most common question ever asked by the users of room thermostats is concerned with setting temperatures. The temperature rises and drops with seasonal changes, and the thermostat’s temperature must be set accordingly to ensure your home is cosy. Experts suggest that during winter, one must set the temperature of your thermostat between 20 to 22 degrees Celsius when you are active and awake.  At night, the temperature outside begins to drop more, so at these times, you can set it between 17 to 19 degrees. The temperature of specific rooms at home is cooler than others. And for them, the temperature has to be set differently to feel cosier. These rooms are your kitchens and bathrooms, and the temperatures can be set between 16 to 18 degrees Celsius.   These setting can be easily done by using a programmable thermostat to set the temperature schedule. No matter thermostat for electric underfloor heating system or thermostat for water underfloor heating system, weekly program function is now becoming a standard function.  We Xiamen E-top Controls Technology Co., Ltd have been engaged room thermostat OEM/ODM service for more than 20 years.

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.
