5 Detachable Calculator
We also provide meters with detachable calculators, in order to simplify
mounting in narrow installation spaces. To release the calculator pull it carefully
up off the flow sensor.
For mounting the calculator on the wall, a wall support is latched onto the
adapter of the flow sensor (between calculator and flow sensor). Remove the
calculator. Hold the adapter of the flow sensor and rotate the wall mounting
support anticlockwise until you can release it. Then attach the wall support at the
desired place
with the flat surface towards the wall.
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
-
high temperature heat meter versions microCLIMA
U (temperature range up to 130 °C)
-
high temperature heat/cooling meter versions microCLIMA
U (temperature range up to 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.
6.2 Direct mounting of the 6 mm temperature sensors of the microCLIMA 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.
