Delta-T Measurement - Ecom EN2 Operating Instructions Manual

13.2. delta-T Measurement

With the ecom-EN2 a difference temperature measurement is possible.
For measurements at pipings (e.g water-in and water-out of heating
systems), special temperature sensors are needed, available from your
authorised rbr agency. Out of the main menu point "Diagnostics" select
the sub-menu "delta-T measurement" and confirm with <Enter>.
The instrument indicates the temperature
T1 (sensor at connection „Gas
temperature"), the temperature T2
(sensor at connection „Air temperature")
and the difference between both
temperatures (T1 - T2). Press <Memory>
to store the result in the intermediate
memory. A printout can be started with
<Print>.
13.3. Heating Check (option)
The heating check is a simple, expressive process to evaluate a complete
heating plant (heat production, distribution and transfer) from the energetic
point of view.
Hereby the single plant components get inspected by the heating engineer
in a combination of measurements and visual assessment and valued in
regards of their energetic quality acc. to a negative point system of
maximum 100 points.
The higher the score, the farer the current plant is away from the
desirable energetic stand and the higher the energy saving potential would
be if modernisation measures are conducted.
In combination with the special probes
required hereto, the ecom-EN2 is able to
perform the measurement of the heating
check parameters: gas losses, ventilation
losses and surface losses.
Out of the main menu point "Diagnostics",
select the sub-menu "Heating Check"
and confirm with <Enter>.
