Temperature set on the valves are to 19c but when the heating turns on, all of the radiators in the house turn on... including the KE100 ones even if the temperature is over 19c. Causing the rooms to go above! I have a Nest thermostat to control my heating. Any reason why this is happening? I have compressed calibrate on all of the TP Link valves. I have also reseated them on the valve but still the same.
