The valve Genius Radiator Valve is allowed to control the temperature of the room because it measures the temperature locally to it and is very good at maintaining a an accurate and stable temperature in the room. The reason for not letting the room sensor Room Thermostat or Room Sensor do this fine control, and the minute-per-minute control of the temperature and plunger position on of the valve is battery life. To maintain a steady temperature in a room the valve needs to measure the temperature every minute, and then adjust its valve position accordingly using TPI (temperature proportional integral) control. It does this by measuring the temperature of the water as well as the room air temperature locally to it. If every time it had to do this it also needed to communicate with another device in the room sensor to get that temperature, then the battery life of the valve and room sensor Radiator Valve would be seriously depleted, or the temperature fluctuations of the room would be considerably large if we reduced the temperature sample rate of the valve.
For this reason with rooms with more than one radiator this the independence of the valves is a very good thing and , because if one end of a large room is colder than the other, then the valves will work independently harder to heat the cold end of the room but will throttle back the warm end of the room. However if the global temperature of the room were to over heat then both valves the room on the app would be shut off and sent the temperature of 4º because the room sensor Room Sensor would pick up the global temperature for this room having gone above the target temperature. |
