3. Mounting the Temperature Sensors
3.1. Installation in temperature pocket
Place the O-ring in the middle
-
groove.
screw nut up to the O-ring.
Holding the screw nut in
-
place, insert the sensor into
the ball valve and tighten the
screw nut.
3.2. Installation in a ball valve
Remove the blind cap or plug
-
and its gasket. Check that all
surfaces are clean.
Place the O-ring in the groove
-
closest to the tip of the
sensor.
screw nut up to the O-ring.
Holding the screw nut in
-
place, insert the sensor into
the ball valve and tighten the
screw nut.
4. Start of Operation
Slowly open the shut-off valves
-
Check for leakage and proper functioning
-
Clean the calculator
-
After confirming that the heat meter is functioning
properly, insert and tighten the sealing wires for
the temperature sensors and the heat meter itself.
When replacing a meter at the end of a verification
period note the meter readings and the serial
numbers of the old and new meters.
Please also check the following points:
•
Is the heat meter the appropriate size?
•
Is the heating system in operation?
•
Are the shut-off valves open?
•
Is the heating system clear (dirt filters not
clogged)?
•
Are the temperature sensors sealed with
wires (to avoid tampering)?
•
Is the directional arrow on the flow sensor
in the correct direction?
•
Is a flow volume displayed?
•
Is a plausible temperature difference dis-
played?
•
For instruments with two external temp-
erature sensors, is the forward flow sensor
(red) in the forward flow and the return flow
sensor (blue) in return flow pipe?
•
For instruments with a built-in return flow
temperature sensor, is the flow sensor
mounted in the return flow?

6. The Display Set-up
The calculator has a liquid crystal display with 8
digits and special characters. The values that can
be shown are divided into three display loops.
•
main loop
•
technician's loop
•
statistics loop
All data is retrieved using the key next to the dis-
play. The standard display has been set to perma-
nently show the total heat quantity consumed since
the meter was put into operation.
At the start you are automatically in the main loop.
By pressing the key longer than 4 seconds you
change to the next loop. Keep the key pressed
until you reach the desired information loop.
To change the information display within a loop,
simply give a short press to the key. In this way,
you can scan all the information in the loop.
After one minute of non-use, the display returns to
the total heat quantity, the standard display.
