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
SensoStar
A
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).
8 Display
The calculator has a liquid crystal display with 8 digits and special characters. The values that can be shown are
divided into five display loops. All data is retrieved using the push-button next to the display.
At the start you are automatically in the main loop (1st level).
By pressing the push-button longer than 4 seconds you change to the next display loop. Keep the push-button
pressed until you reach the desired information loop.
By pressing the push-button briefly each time you can scan all the information within a loop.
After 2 minutes of non-use of the push-button, the display will automatically be deactivated.
