6 Mounting the Temperature Sensors
During installation of two exterior temperature sensors (symmetrical) make sure that the (right) temperature
sensor with the following drawing is mounted into the same pipe line as the flow sensor:
6.1 Direct mounting (ball valve and T-piece)
- Remove the blind plug / old temperature sensor and gasket / old O-ring. Clean
connection surfaces.
- Slide the O-ring off the temperature sensor and insert it to the bottom of the
threaded opening of the ball valve or the T-piece.
- Hold the temperature sensor at the screw only and insert it into the ball valve or
the T-piece and screw tightly.
- In doing so the plastic clip is locked in the first crimp (viewed from the top of
the protective sheath) and must not be moved.
6.2 Direct mounting of the 6 mm temperature sensors of the
Important note:
Close the shut-off valves and make sure that no hot water can escape upon removal of
the blind plug or the old temperature sensor!
- Prepare both temperature sensors: Push the O-ring into the first crimp (seen from
the top of the protective sheath).
- Insert the temperature sensors into the measuring point of the connection piece,
and ball valve or T-piece, and tighten using the coupling nuts.
- Reopen all ball valves and check installation points for leakage.
- Protect the installation points (meter and temperature sensors) against
manipulation by securing with the seals and sealing wires.
7 Start of Operation
- Slowly open the shut-off valves.
- Check that there are no leaks.
Check the following points:
- Are all shut-off valves open?
- Is the meter of the right size?
- Is the heating (heating/cooling) system clear (dirt filters not clogged)?
- Is the temperature sensor installed in the flow sensor correctly sealed to the flow sensor?
- Does the directional arrow on the connection piece / flow sensor match the actual direction of flow?
- Is a flow volume displayed?
- Is a plausible temperature difference displayed?
When the meter is functioning properly, attach the seals to the exterior temperature sensors and the flow sensor
(required to protect against manipulation).
