5.1 Switch on the instrument panel
For operation of the boiler Gas 610 ECO PRO:
The features and instructions described are for each boiler
module.
The instrument panel HMI GAS 310/610 ECO PRO is ready for use,
as soon as the power to the boiler is switched on.
1. Open the gas valve on the boiler.
2. Turn on the boiler using the on/off switch.
3. Set the controls (thermostats, control system) so that they request
heat.
4. The start-up cycle begins and cannot be interrupted. During the
start-up cycle, the display shows the following information:
A short test where all segments of the display are visible.
fK[xx : Software version
pK[xx : Parameter version
The version numbers are displayed alternately.
By pressing the S key for a short time, the current operating status
is shown on the display:
Heat demand Heat demand stopped
1 : Fan ON 5 : Burner stop
" : Boiler is igniting 6 : Post-circulation of the pump
3 : Heating System 0 : Standby
In STAND-BY, the display normally shows the water pressure next to
0 (only when the hydraulic pressure sensor is connected) and the
symbols D and H.
Error during the start-up procedure:
4No information is shown on the display:
-Check the mains supply voltage
-Check the main fuses
-Check the connection of the mains lead to the connector in the
instrument box (Check the fuse F2 = 10 AT)
-Check the fuses on the control panel:
(F1 = 2 AT)
4A fault is indicated on the display by the fault symbol c and a
flashing fault code.
-The meaning of the error codes is given in the error table.

5.3 Changing the settings
The boiler control panel is set for the most common heating
systems. With these settings, practically all heating systems operate
correctly. The user or installer can optimise the parameters according
to own preferences.
For the settings of the Gas 610 ECO PRO boiler:
The parameters and settings described are for each boiler
module. Each parameter changing must therefore be done
identical on each module.
