I called the gas man out. He reset everything and it's working how it should. Continuous means system on as per thermostat. He doesn't know why it was firing up earlier with the temperature set lower than the room temperature. Strange
Now I have the issue of temperature in the property. Before it was kicking in often so heat would be felt. Now with the room temperature reading being correct it's not firing up. I feel the cold chill even though it's hot enough to be comfortable.
What's your thermostat temperature set at? Mine is set to 20c.
