Aredwood: Glad everything is working well. This is reminding me about the extra things I need to do on my system. Main ones being installing radiators in the lounge and bathrooms. As the temp in my room currently is 24deg while the lounge is 16deg. Also need to add active water temp management to my system. So the oil feed rate into the boiler will be varied based on how much heat is needed. And then I will be able to add thermostatic radiator valves to the radiators. So this problem won't happen again
That wall thermostat is not actually connected to anything, It is there solely to monitor the temp. It's not set to the correct time either.
Wow a Chronogyr. Is it Landis and Gyr branded?
