I have a problem with rooms getting too hot, I have tried replacing the TRV heads for electronic ones, and adjusting the lock shield valves, much improved, but room for further improvement.
It seems the anti hysteresis software in the hall thermostat is likely causing the hysteresis in every other room? As room cools the valve opens, but if boiler not running it can open too much, then when boiler does run, the valve can't close fast enough, and with boiler switching on/off so often due to type of wall thermostat the TRV heads simply don't know what to do.
So what happens if I turn down boiler temperature, would I need to open the lock shield valves more or leave as they are? How do you know what to set it to?
