Mounting the temperature sensors 6 mm of the MSH-AStar
5.2.1
Direct-mounting the temperature sensors of the MSH-AStar
Important notes
-
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 middle groove.
-
Insert the temperature sensors into the measuring point of EAT 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.

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)?
-
Are the temperature sensors and the flow sensor sealed (against manipulation)?
-
Is a flow volume displayed?
-
Is a plausible temperature difference displayed?
When the meter is functioning properly, attach the seals to the temperature sensors and the flow sensor
(required to protect against manipulation).
