4.10. Connection of the mixers
The ESBE mixers are connected as three-pole ac-
cording to the wiring diagram enclosed.
Mixer open = brown
Mixer closed=black
4.11. System Ear thing
When the protective conductor is connected correctly,
the electrical panel and the heat pump casing are
earthed.
After maintenance work, ensure that the equipotential
bonding is properly re-established.
4.12. Maximum restriction for under floor
heating:
With underfl oor heating circuits, an additional clip-on
thermostat must be fi tted and the relevant heating
circuit pump supply switched via it in series.

4.13. Composite signal zone valves
The composite signal zone valve setting generates
a request when one of the zone valves is open. The
difference to a room thermosta function is that, inde-
pendently of heating or cooling operations, a request
is generated when a zone valve contact is closed.
If you are using zone valves, you can
generate composite signal from all zone
valves to be able to switch the heating
and cooling circuit on and off with the
thermostat function.
