3.1
Installation of cooling meters and combined
heat/cooling meters
Fit the electronic unit separate to the volume measurement
unit, e.g. on the wall for water temperatures below 10° C. Make
a loop downwards in order to prevent condensation running
along the connected lines into the electronic unit. Install the
temperature sensors into the pipe from below.
Note:
Wall adapter plates are available as an accesso-
ry.
3.2
Electronic unit
The ambient temperature of the electronic unit must not ex-
ceed 55 °C. Avoid direct sunlight.
Aligning electronic unit
Proceed as follows to align the electronic unit:
•
Turn the electronic unit to the left or right through 90° or
through 180° as required.
Note:
When turning through 45° the electronic unit is
not connected tightly to the volume measurement unit.
Wall fitting (split fitting)
Fit the meter to the wall at water temperatures below 10 °C.
Proceed as follows:
•
Fit the wall adapter plate (available as an accessory).
•
Turn the electronic unit through 45°.
•
Pull the electronic unit away from the volume measurement
unit.
•
Place the electronic unit on the wall adapter at an angle of
45° and turn it into position.
3.3
Power supply
The meter is equipped with a long life battery for 6 or 11 years
of operation. You can take the operating time from the dial
plate.
Warning:
Do not open the batteries. Do not bring
battery into contact with water or expose to tempera-
tures above 80 °C. Dispose of used batteries at suita-
ble collection points.
3.4
Interfaces and Communication
The meter is equipped with an optical interface in accordance
with EN 62056-21 as standard. If the meter is equipped with
the option "M-Bus", it is supplied with a 2-wire cable which you
can extend by fitting a junction box.

Switching the display
Proceed as follows to switch between the display values:
•
Press the button briefly (for less than 2 sec.) to show the
next line of the current loop.
After the last line is displayed, the first line comes up again.

If you do not operate the meter for 30 sec. in the user loop
"LOOP 0", the meter changes to the standard display. If you do
not operate the meter for 30 min. in the loops "LOOP 1 ... 4",
the meter changes to the standard display.
