Delta-T Measurement; Heating Check (Option) - Ecom EN2 Operating Instructions Manual

13.2. delta-T Measurement

With the ecom-EN2 a difference temperature measurement is possi-
ble. For measurements at pipes (e.g. water-in and water-out of heat-
ing systems), special temperature sensors are needed, available
from your authorized ecom agency. Out of the main menu point "Di-
agnostics" select the sub-menu "dT measurement" and confirm
with <Enter>.
The instrument indicates the tempera-
ture T1 (sensor at connection „Gas
temperature"), the temperature T2 (sen-
sor at connection „Air temperature") and
the difference between both tempera-
tures (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 modernization 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 "Diagnos-
tics", select the sub-menu "Heating
Check" and confirm with <Enter>.
