What is the relationship between radiator, thermostat and extension kit?
I used to have just smart valves everywhere, the thermostat in the hall, and an old analog style timer in permanently ON position for heating. Worked a charm.
I added the extension kit and can now control HW too - great - except something has changed. The radiator valves no longer turn the boiler on. The thermostat does, but that means I have to heat the hall if I want to heat any other room. This is not cost effective, and not what I wanted.
e.g. My hallway is 19.1, set to 18. My living room is 17, set to 20 - so should be heating but is not. If I override the hall schedule to, say, 20, it kicks in and heats the hallway and the living room.
Is this how this is SUPPOSED to work with an extension kit? If so can I reconfigure it somehow so radiator valves trigger heating, or do I have to rewire something somewhere?
As an aside I am still using the 230V switched (wired) settings as I replaced the thermostat first, and added the extension kit later.
Thanks in advance.
