Description of functions and graphic contexts displayed by the control panel LMC1X
6.2.1
Graphical context - Display the E88 error
When power supply the boiler, on the control panel, the "- -" welcome message will be displayed, followed immediately by the
boiler input to the E88 (
) error.
This will indicate the need commissioning, by one of the service companies authorized under the laws in force and approved
by us, KÖBER SRL.
To do so, contact one of the partner companies within your home range listed on the list within the Warranty
Certificate.
For testing the boiler at pressure by the installer, pressure is displayed on the analog pressure gauge mounted under the boiler.
Removing the boiler from the E88 error requires:
- breaking the boiler seal (self-destruct label on the left side / central cover).
For the guarantee, this operation is only permitted by authorized and approved personnel of KÖBER SRL.
6.2.2
Graphic context – switching the boiler on control panel LMC1X
At startup, the boiler is in an intermediate state for 5 seconds that is required to boot the system.
By the point of view of the interface with the user, there are two different modes of function, that depend of
the boiler`s status:
- in case that, before disconnecting the board from the network, the boiler was “ON”, then the symbol S1
(the high digits) will display the message “HELLO” (see figure 6.2.1);
- in case that, before disconnecting the board from the network, the boiler was “OFF”, then on symbol S1
(high digits) will not display anything (see figure 6.2.2).
6.2.3
LIGHT function control panel LMC1X
LIGHT
key (
J11
fig.6.1) It is used to enable / disable the backlight, except when starting the application
and display of errors.
6.2.4
Graphic context - Stand-by control panel LMC1X
This context is associated with an inactive state / a waiting boiler. In standby status all actuators/state
elements are inactive and any request for combustion is ignored.
The exception to this rule:
antifreeze function
(generated by a value system water temperature less than 9°C, which will initiate a
cycle of combustion heat to prevent freezing the thermic agent from the pipes.
Entry and exit from this mode by pressing the
POWER
key at least one second. The commutation between those two menus it
sets, the status of the boiler in OFF or ON. J6 – POWER key is active in every other menu to facilitate the forced off of the boiler in
case of abnormal function.
Possible actions:
-
POWER
– switching between ON/OFF;
-
RESET
– used to reset possible errors.
Figure 6.2.3 is an example of the display in standby state (heating boiler pressure 1.2 bar)
6.2.5
Graphic context – on hold (ON) control panel LMC1X
The on-hold state is associated with a state of operation of the boiler, but where no burning request appears. In this
condition/state, all actuators of the boiler are active and any burning request is accepted, if no error is present. In this state the
user can visualize all the information about the boiler and make the desired settings.
Possible actions:
-
MENU/OK
– activates the user menu;
-
POWER
– turns the boiler on/off;
-
IN/SU
– selects the operating way WINTER/SUMMER;
-
INFO
- changes the information displayed by symbol S1 (pressure, heating temperature, DHW temperature);
-
LIGHT
– enables / disables the display backlight;
-
RESET
- used to reset errors.
