Programmable Thermostat Timer TRV Thermostatic Radiator for 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 for valve also known as electric for valve, is a new concept for water for valve device, suitable for housing, shopping mall, hotel heating and central conditioning temperature control, room temperature control. Features: The thermostatic radiator valves is a special for 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 for valve instead of installing an actuator plus temperature control for valve. Applied to electric drive part of the electric heating actuator of branch for valve, small for valve and dynamic balance for 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.
