Programmable Thermostat Timer TRV Thermostatic Radiator Valve Actuator Thermostat Heater Thermoregulator Temperature Controller Overviews: This actuator will fine turning for valve status of opened, according to room temperature and setting temperature to meet better status of power saving for put off the working life of battery. Radiator actuator valve also known as electric valve, is a new concept for water valve device, suitable for housing, shopping mall, hotel heating and central air conditioning temperature control, room temperature control. Features: The thermostatic radiator valves is a special valve using cooperatively with heating radiator. Artificially set indoor temperature, mainly used in the floor heating system to control the closing and opening of the pipe. Adjust the flowing through the radiator without the need for external power hot water flow to realize the constant room temperature. Directly control the water valve instead of installing an actuator plus temperature control valve. Applied to electric drive part of the electric heating actuator of branch valve, small valve and dynamic balance valve. Nut connection installation method, easy and fast to install, convenient to disassemble. 1.6" blue backlight LCD screen display and 5 buttons makes it easier to read and set the value in dark.
