• Run the warm side temperature sensor cable from the
outside through the 4th grommet from the left and the
cold side temperature sensor of the through the 5th
grommet from the left.
• Strip both cables as shown in the illustration.
Figure 12: Temperature sensor connection
• Connect the wires according to the printed wiring
diagram. The connection is made to terminals 5/6
(warm side temperature sensor) and 7/8 (cold side
temperature sensor).
• Insert the temperature sensors into the thermowells,
ball valves or T-pieces. The temperature sensor must
sit on the bottom of the thermowell.
• Seal the temperature sensors to prevent manipulation.
• Close the housing cover by tightening the screw (see
chapter Torque) and press the housing cover tightly
into place.
If the LCD displays
via the parameterisation menu. Please refer to the service
manual.
10 Commissioning
Proceed as follows when carrying out the commissioning:
• Close the housing cover by tightening the screw (see
chapter Torque) and press the housing cover tightly
into place.
• Slowly open the gate valves.
• Check the system for leaks and vent it carefully.
The message F0 disappears after 100 s at the latest.
• Check the flow and temperature indicators for
plausibility.
• Vent the system until the flow display [ID 000] is stable.
• Attach user guards to the calculator and temperature
sensors.
• Document the meter readings.
Recommendation: Reset the maximums and the
absence time. More details can be found in the T450

Error "Incorrect flow
direction (negative)"
Check whether the flow
direction arrows on the
volume meter correspond to
the flow direction of the
system. If the directions do
not match, rotate the volume
meter 180°.
Error "negative

Check whether the
temperature sensors are
correctly installed. If the
temperature sensors are not
correctly installed, swap the
installation location of the
temperature sensors.
