Heat quantity measurement
The heat quantity measurement can be carried out in 2 different ways: without V40
owmeter or with V40 owmeter
Note
The most precise heat quantity measurement is achieved by using sensors
in the ow and return pipes as well as a owmeter.
In 2-collector systems, heat quantity measurement can only be carried out
with sensors installed in the common ow and return pipes.

Example of ow and return sensor positions for heat quantity measurement.
Î Enable the heat quantity measurement option in the channel OHQM.
Î Select the type of ow rate detection in the channel FTYPE.
Flow rate detection type:
1 : Fixed ow rate value (owmeter)
2 : V40
Note
If the ow rate detection type V40 has been adjusted,the impulse rate of
the sensor must be adjusted in the SENS menu (see page 47).
Note
If a V40 is used as the ow rate sensor (ow rate detection type 2) and is
then deactivated in the SENS menu, the ow rate detection type will be
set to 1 (owmeter) and heat quantity measurement will be deactivated.
