Long range controller doesn’t need exterior power while automatically sensing to adjust and maintain the temperature, normally used for underfloor heating systems. It is easy to fix and dismantle.
 
Long range controller is used screw to joint on the control valve body, by adjust the controller to set the temperature range. This can keep the temperature to a certain point, in case to set at a wrong point ,keeping flow rate to a steady range.
 
Temperature setting
For example, you can use it to control the return water of the floor heating system, temperature of the hot water tank and so on to reach your desigred tempearture. Two temperature range can be choosed:For room: 6-28degree ; For underfloor heating system: 30-70degree
