The boiler codes, 1 and 2, can be reset by the user by selecting selector 39) in Fig. 1 in
the reset position
If the block persists, contact the Sile Service Centre.
A block with 10 code can be caused by a lack of water in the system, or from the
circulating pump blocked or faulty. In The first case check that the system load pressure
on the boiler pressure gauge is approximately 1÷1.3 bar; in the second contact the Sile
Service Centre
For all remaining block codes that do not reset even after switching off the boiler and then
switching it on again, contact the Sile Service Centre.
1.4 Boiler shutdown.
To shut down the boiler turn the selector to the position off and turn the gas valve off. If
the boiler is not used for long periods of time, always close the main gas supply tap and
turn off the main power supply switch. In this mode antifreeze system remains active. For
a complete turn off the power supply to disconnect from the outside boiler.
1.5 Operating of the solar system
(to be activated only if the Solar System 2 sensor kit has been installed)
The solar function can be activated in the summer and winter to integrate the sanitary hot
water. It is activated using parameter 4 whose configuration mode is described in
paragraph 3.2
If you only wish the solar mode to be activated, normally in the summer, you can select
one of these configurations. Remember that parameter P4 must always be activated by
selecting value 1 :
1. status selector (39 Fig. 5) = SUMMER or with status selector = OFF;
2. heating set point selector on minimum;
The board only works in solar mode.
In the solar only mode, any external burner start-up request (sanitary request) is
deactivated whereas the anti-legionella and anti-freeze functions remain active.
In the “solar only” mode, the solar panel icon and collector temperature are shown on the
display
