Dual HIU dashboard example

This is a simple demonstration of how columns can be used to display multiple dashboards on a screen at once.

The benefits of being able to test different settings and functions out on live systems in the field is a significant advantage. With numerous systems on a development, it become much easier to optimise controls functionality than in a laboratory or R&D environment. The random element introduced by the real world shows up problems, and it is possible to run adjacent systems with different settings to compare outcomes under similar heating loads.

The system on the left is running compensated heating functions, while the system on the right is running fixed temperature heating.

These HIUs are part of a field trial to understand the limits of return temperature performance that can be achieved with some more advanced HIU functionality. The key difference can be seen in the VWART (average return) figures on central heating. Both systems are fitted with the same radiator systems, unbalanced with a 10C drop. See http://heatweb.co.uk/w/index.php?title=Radiator_Optimisation for more information on this trial.
