4.8. Assignment of the outputs
Configuration for the outputs of according to the
wiring diagramm
4.9. System ear thing
When the protective conductor is connected correctly,
the electrical panel and the heat pump casing are
earthed.
After all maintenance work, ensure that the potential
equalisation has been restored correctly.
4.10. Maximum restriction for underfloor
heating
With underfloor heating circuits, an additional clip-on
thermostat must be fitted and the relevant heating cir
-
cuit pump supply switched via this thermostat in series.
4.11. 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 thermostat function is that, inde-
pendently of heating or cooling operations, a request
is generated when a zone valve contact is closed.
4.12. Connection external preselected target
value 0-10V
For the connection of the external preselected
target value 0-10V the input of the RFF room
sensor is used. The external 0-10V signal will
indicate the desired temperature for the regu-
lation.

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.
