Understanding the Graphs in Your Heating History

In your Heating History, there are three types of graphs:

Usage Graph: Each of the blue bars shows your overall usage for that given time period. To the right of this graph, you will also see the max/min outdoor temperature for the time period. These are visible in the week/year view.

Active Heating & Indoor Temperature Graphs: Within day view, there are two graphs:

• Active Heating: The left-hand graph shows when your boiler fired up each day and for how long.
• Indoor Temperature: The right-hand graph plots out your indoor temperature throughout the day.
