In this guide you will learn how to read the SWC Detailed Report in Leanheat® Monitor, which breaks the Smart Weather Compensation results down to a single month, device and heating circuit. For the overview across all devices, see Reading the SWC Performance Report.
Where the Performance Report answers "how are we doing overall", the SWC Detailed Report answers "which circuit produced that result". It is visible to every user role, and like the Performance Report it only lists the devices you have access to.
Filtering the table
The heating season currently in view is shown at the top left. The report always shows one month at a time, and you choose it with the filters:
"Select month": the month within the season whose figures you want to see.
"Assigned devices": narrows the table to the devices you pick.
"Circuit name": filters by the name of the heating circuit.
"Reset filters": clears everything and returns to the full table.
If a combination of filters matches nothing, the table shows "No data for selected filters".
The columns
Each row is one heating circuit of one device, for the selected month. A device with several circuits therefore takes up several rows, and the device name is repeated on each.
"Device name": the controller, with its address underneath.
"Heating circuit": the circuit this row refers to. Circuits that have been given a name in Leanheat® Monitor show that name. Circuits without one are numbered, for example "Circuit #1".
"Avg. flow T, normal [°C]": the average flow temperature the circuit would have run at without SWC.
"Avg. flow T, SWC [°C]": the average flow temperature it actually ran at with SWC.
"Avg. SWC effect [°K]": the difference between the two, shown as a negative number because SWC lowers the flow temperature.
"Estimated savings %": the estimated saving on space heating for that circuit in that month.
Sorting works on the device name column, using the arrow in the header.
Reading a row
The three temperature columns belong together. A circuit showing a normal flow temperature of 43.3°C, an SWC flow temperature of 39.5°C and an effect of -3.8°K ran on average 3.8°K cooler than it would have without SWC, and the rightmost column translates that into the estimated saving.
Comparing rows is often more useful than reading one on its own. Circuits in the same building rarely benefit equally, and the ones with the smallest effect are usually the ones worth looking at.
Rows without a result
A row can show the same value in both flow temperature columns and leave the effect and savings cells empty. That means no SWC effect was calculated for that circuit in that month.
This is normal in a month where a device was enrolled late, paused for most of the period, or offline. If a circuit stays empty across several months while its neighbours produce results, it is worth contacting Danfoss support with the device serial number so the circuit can be looked at.
How the figures are calculated
The calculation method is the same one used for the Performance Report and is explained in How SWC savings are calculated.
