Hello,
I have a HIVE thermostat and a Worcester Bosch boiler. I have noticed recently that my boiler fires up even though HIVE hot water and heating are set to off.
Any ideas why this may be?
Thanks
 
Im guessing you have a 3 port valve? If so, it could be getting a signal from a stuck motor or faulty microswitch.
