INTEGRA Metering AMTRON S3 Installation And Operating Instructions Manual page 15

We always recommend detaching the calculator from the flow sensor.
However, it is important to note that the calculator must be detached for the following versions:
- Cooling and heat/cooling meters
- optional high temperature heat meter versions
- optional high temperature heat/cooling meter versions
120 °C).
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.
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.
