1.8.4. Flow Monitoring
System flow is monitored whether or not a flow meter is installed.
If no flow meter is installed
x
the difference between collector temperature and tank temperature is used as indication
of an error in the flow.
x
A difference of greater than 140°F for more than 30 minutes is interpreted as an error.
x
When a flow meter is installed
x
If no flow has been measured for ten minutes after the pump engages, an error is
indicated.
When an error is detected, an error message is shown in the display.
1.9. Energy Measurement
The Advanced Solar Control has multiple options for measuring energy. Both instantaneous
energy (
kBTU/h
) and accumulated energy (
kBTU
) are displayed on the
Main Display
screen.

constants:
x
Flow can either be input by the user or
measured by various types of flow sensors
(see section
1.8 Sensor Options
).
x
Fluid constants will depend on whether the
system contains glycol or not. If glycol is
used, the percentage can be selected in
section
1.12 Glycol.
x
The Advanced Solar Control has multiple

sensors as well as the locations in the
system across which they want energy to
be measured.
