Should the external sensor be fitted it will be necessary to set the
heating curve (see page 41) and may be necessary to adjust the
parallel shift depending on the performance of the heating system
used.
If the temper
ature in the house is too high, it will be necessary to
decrease the parallel shift, whereas if the temperature is too low it will
be necessary to increase the parallel shift as described below.
To set up the external sensor proceed as follows;
1. Access the settings menu by pressing the and buttons
for five seconds;
