PEGASUS D 30 K 100 LN
Sliding Temperature
When the optional external probe is installed the control panel display (detail 5 - fig. 1)
shows the actual outside temperature read by the probe. The boiler control system op-
erates with "Sliding Temperature". In this mode, the temperature of the heating system
is controlled according to the outside weather conditions, to ensure high comfort and en-
ergy saving throughout the year. In particular, as the outside temperature increases the
system delivery temperature decreases according to a specific "compensation curve".
With Sliding Temperature adjustment, the temperature set with the heating buttons
(details 3 and 4 - fig. 1) becomes the maximum system delivery tempera-
ture. It is advisable to set the maximum value to allow system adjustment throughout its
useful operating range.
The boiler must be adjusted at the time of installation by qualified personnel. Adjust-
ments can in any case be made by the user to improve comfort.
Compensation curve and curve offset
Press the button
(detail 10 - fig. 1) once to display the compensation curve (fig. 11),
which can be modified with the DHW buttons
Adjust the required curve from 1 to 10 according to the characteristic (fig. 13).
By setting the curve to 0, sliding temperature adjustment is disabled.

fig. 12 - Parallel curve offset
Press the button
(detail 10 - fig. 1) again to exit parallel curve adjustment mode.
If the room temperature is lower than the required value, it is advisable to set a higher
order curve and vice versa. Proceed by increasing or decreasing in steps of one and
check the result in the room.

Operate the filling cock (detail 1 - fig. 16) and bring the system pressure to a value above
1.0 bar.
