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
