Uponor Smatrix Wave PLUS U@home R-167 – U@home web access l 21
U@home can save and show the temperature values of the
system during the last 24 hours and 7 days, as well as other
information related to system performance:
• Temperature for each room.
• Setpoint for each room.
• Average temperature in the system.
• Outdoor temperature, if there is an outdoor sensor
installed.
• Utilization factor, which provides an indication of the
energy efficiency of the system.
This information can be viewed by clicking the statistics
(trends) icon on each room page. If you are unable to find
this shortcut, please see the section “Basic use of U@home”.
Trends and utilization factor
A new page is opened with two graphs:
• The first graph provides temperature information for that
particular room, comparing room temperature, setpoint and
outdoor temperature when available.
• The second graph represents system temperatures,
i.e. average temperature in the house and outdoor
temperature when available.
On top of this page, there are two buttons to select which
kind of view you would like to see: 24 hours or 7 days.
In the bottom part of this page you can see the utilization
factor of all rooms and, highlighted in blue, the current room.
It indicates the percentage of time that heating or cooling is
on (actuator open). High percentages normally indicate lower
energy efficiency.
The following points provide some possible interpretations of
the results:
• If all rooms have a low utilization degree (less than
30 – 40 %), system supply is unnecessarily high.
• If all rooms have a high utilization degree (over 70 – 80 %),
system supply is too low.
• If autobalancing is active, long loops will cause a higher
utilization factor. Please check your Uponor Smatrix Wave
PLUS manual.
• If you have a high utilization factor but the room is cold,
check the actuator and the manifold valve for that zone.
Please contact your installer to check the utilization factor
results and improve the energy efficiency of your installation.
