WARNING
(*) - If curve 0_3 or 0_5 is set, a system
safety thermostat must be connected to
the main terminal board (see paragraph
2.10)
With parameter P 5 it is posslbe to adjust the heat curve
setting to those shown in fig. 4.16). Using programming keys
and
, the curve setting may be changed. The possibility of
setting curves varies according to parameter r:
r = 00 (low temperature range) from curve 0_3 to 0_5 (underfloor
systems only)
r = 01 (high temperature range) from curve 1_0 to 3_0.

ETTING THE
(Only enabled when an outdoor sensor is installed)
When using an outdoor sensor, the microprocessor-controlled P.C.B.
calculates the most suitable flow temperature, taking into account
the exter nal temperature and the type of system. The
microprocessor is capable of doing this because it is possible to
establish a link between the external temperature and the flow
temperature of the Central Heating system water. This link translates
into a "thermal curve".
The type of curve should be chosen in correspondence with the
planned temperature of the system and the nature of the heat loss
present in the building.

Test Function
The P.C.B. allows the boiler to be forced to the maximum or
minimum power. Enable the test function and OO will appear on
the right-hand display (see Fig. 3.8).
To select operation at maximum power, press the programming
key
, two dashes will appear at the top of the right-hand
display (see Fig. 3.9).

key
, two dashes will appear at the bottom of the right-hand
display (see Fig. 3.10). This function is disabled when you press
reset key "H" to quit the adjustments menu.

automatically forced to test mode and t-- will be displayed,
the boiler is now in the test mode for the maximum heating
