Following instructions refer to the energy calculator.
The regulations on the use of energy meters must be observed! The
meter installation is only to be performed by an installation and/
or electrical contractor using personnel trained in the installation
and use of electrical equipment and familiar with the Low Voltage
Directive.
- The specied absolute temp. measuring range
is 0 ... 90°C/105°C/180°C
- The temperature range depends on calculator variant
- The exact temperature range is shown on the type plate
- The specied operating/ambient conditions are:
5…55 °C; max. 93% rel. humidity
- Protection class: IP54;
- Ambient temperatures below 35 °C ensures typical battery
lifetime
This installation guide is intended for trained personnel and
does not contain any basic working steps.
If the ow sensor is insulated with the pipeline,
the calculator must be accessible.
Safety Note
The seal on the energy calculator must not be damaged!
A damaged seal will result in immediate invalidation of the
factory warranty and verication. The cables supplied with the
calculator must not be shortened, extended or changed in any
other way.

Make sure the energy calculatorv is installed suciently far away
from possible sources of electromagnetic interference (switches,
electric motors, uorescent lamps, etc...)
.
The energy calculator should be installed in an accessible position
for service and operating personnel.
Initial operation is to be carried out and recorded after installation.
For medium temperatures of more than 90°C or if T
water
< T
ambient
(for application as cooling meter or heat meter with cooling tari),
the calculator must be removed from the ow sensor and installed
asucient distance away from heat sources.
A wall holder (supplied with meter) or a space holder (optional) is
available for this purpose.

Handle the temperature sensors carefully!
The sensor cables are tted with coloured type labels:
Red (TH): sensor in hot line,
Blue (TC): sensor in cold line
Make sure the sensors are mounted symmetrically (both directly
immersed, or both installed in a pocket). The maximum cable length
is 10 m. The connecting cables must not be shortened or extended.
The free temperature sensor can be installed in a ball valve /adapter
or in a conformity tested pocket for this type of sensor. Ensure that the
temperature sensors are permanently connected during operation.
For installation in a ball valve (same for adapter), a 4-piece coupling
set is enclosed in a separate bag. See procedure under item 1…5
on the right. Insert an O-ring in the sensor hole using the mounting
pin supplied.
If the sensor is installed in a pocket, it must be inserted as far as the
bottom of the pocket and then secured. The pockets are best installed
in T-pieces with a 45° or 90° angle. The tip of the pocket must point in
the opposite direction to the direction of ow and must be located
in the middle of the pipe.
The temperature sensors must be sealed after installation in the
pockets.
Connect the sensor cables to terminals as shown below.
- For 2-wire connection to terminal 5-6 and 7-8
- For 4-wire connection to terminal 1/5 - 6/2 and 3/7 - 8/4
