Regulation of the external sensor
(fig. 2/a)
If an external sensor is installed, the value
of the output temperature is automatically
chosen by the system, which quickly adjusts
the environmental temperature on the ba-
sis of the external temperature. If you wish
to change the value of the temperature, in-
creasing or decreasing that calculated au-
tomatically by the electronic card, proceed
as indicated in the preceding paragraph.
The level of various correction of a value of
temperature proportional calculated. The
display will be as shown in fig. 2/a.
TO SWITCH OFF THE BOILER (fig. 1)
In the case of a short absence, press the
key (
) of the controls (pos. 2). The di-
splay will be as shown in the fig. 1. In this
way, leaving the electricity and the fuel
supply connected, the boiler is protected
from frost and from the pump becoming
jammed. If the boiler is not used for a pro-
longed period, it is advisable to disconnect
the electricity supply, by switching off the
main switch of the system, and to close the
gas isolation valve and, if low temperatures
are expected, to completely empty the
hydraulic circuits to avoid pipes being da-
maged by frost.
ERRORS AND SOLUTIONS
When there is a functioning error, the di-
splay shows an alarm and the blue lumi-
nous bar becomes red. Descriptions of the
errors with the relative alarms and solu-
tions are given below:
– ALARM 02 (fig. 3/a)
If the water pressure detected is lower
than 0.5 bar, the boiler will stop and the
display will show “ALL 02”.
Using the external filling device, repres-
surise until the pressure indicated by the
display is between 1 and 1.5 bar (98 and
147 kPa).
If it is necessary to repeat the system
refilling procedure, it is advisable to
contact qualified technical personnel to
check the seal of the heating system (to
check whether there are any leaks).
