Heat flow meter
Installing the heat meter
Optionally, a heat meter can be installed in the heat
transfer station. This is available separately from ETA.
1. Remove the front cover and switch off the heat
transfer station on the mains switch.
2. Block the flow and return lines on the primary side.
3. Remove the adapter in the return line. Hot water
may leak out.
Fig. 4-14: Adapter
4. Insert the measuring unit of the heat meter. During
installation, make sure the direction of flow is
correct for the measuring unit.

5. The temperature sensors of the heat meter are
colour-coded (flow = red, return = blue). Insert
them into the immersion sleeves at the flow (red)
and return (blue) connections of the primary circuit.

Depending on the heat meter, a return
temperature sensor may already be installed
in the measuring unit.
6. The display of the heat meter can be attached to
the front of the heat transfer station.

7. Connect the heat meter electrically. See chapter
.
8. Open the flow and return lines of the primary circuit
and bleed the primary circuit. Switch the heat
transfer station back on at the mains switch and
refit the front cover.
