9.2.5
Graphic context – waiting state
Waiting state is associated with a functioning state of the station, but with no
burning request. All the activating/state elements of the central heating
station are active and all burning requests are accepted if no error is present.
In this state, the display shows pressure and thermal temperature, as well as
the functioning mode summer/ winter.
-
Normal errors: all the activating/state elements of the central heating station are active and
any burning request is ignored. Getting out of a normal error state is done by pressing the RESET
key;
-
Informative errors: all the activating/state elements of the central heating station are active
and all burning requests are accepted. Getting out of an informative state is done
automatically when the cause of error disappears.
In this context the diplay flashes a message with the error code.
Possible actions:
-
RESET
– reset critical or normal errors;
-
LIGHT
- activation or deactivation of light functions – possible only if the central heating station
is not in a state of critical error. Figura 1.11 is a good example of display of an error (in our case
E20).

9.2.1 LIGHT function
LIGHT
key (J8 fig.1.5) is used to activate/ deactivate the light on display
function.
9.2.2 Graphic context – station startup
When started, the station is in an intermediary state for 5 seconds,
necessary to initialise the system. During this interval the diplay shows only
the message “
On
” on the S1 symbol on the interface (see figure 1.9).
9.2. 4 Graphic context – error state
The display of an error is sometimes asociated with a state of
malfunctioning/ error of the station. There are three types of errors:
Critical errors: all the activating/state elements of the central heating
station are inactive and any burning request is ignored. Getting out of this
critical error state is done by pressing the RESET key;
9.2.3 Graphic context - Stand-by
This context is associated with an inactive/ waiting state of the central heating station. In the
stand-by state all the activation elements are inactive and every burning demand is ignored.
An exception to the rule:
the anti-freezing function
(generated by a value of water
temperature in the installation lower than 9°C, which will initiate a burning cycle to prevent the
freezing of the thermal agent in the installation.
Entering and exiting this regine is done by pressing
POWER
key for at least one second.
Possible actions:
-
POWER
– comute between ON/OFF states;
-
LIGHT
– activation or deactivation of light functions.
Figure 1.10 is a good example of display in the stand-by state (pressure on the thermal
installation 1,8 bar).
