5.1 Switching on the control panel
Note
Operating the Gas 610 ECO PRO boiler: the properties described
and the instructions apply to each boiler module.
The HMI Gas 310/610 ECO PRO control panel is ready for use as soon as
the power to the boiler is switched on.
1. Open the main gas tap.
2. Open the boiler gas tap.
3. Switch the power on with the boiler's on/off switch.
4. Set the components (thermostats, control) so that heat is deman
ded.
5. The start-up program will start 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:
: Software version
: Parameter version
The version numbers are displayed alternately.
By pressing the key for a short time, the current operating status is
shown on the display:
Tab.2 Operating status
Heat demand Heat demand stopped
: Fan on : Burner stop
: Boiler is attempting to ignite : Post-circulation of the pump
: CH operation : Standby
In STAND-BY mode the display normally shows as well as the water
pressure (only when the hydraulic pressure sensor is connected) and the
and symbols.
Error during start-up procedure:
No information is shown on the display:
Check the mains supply voltage
Check the main fuses
Check fuses: F2 = 10 AT and F1 = 2 AT.
Check the connection of the mains lead to the Mains connector in the
instrument box
An error is indicated on the display by the error symbol and a flashing
error code.
The meaning of the error codes can be found in the error table.
Press the key for 3 seconds to restart the boiler.

8.2 Error memory
The boiler control unit has an error memory. It stores the last 16 errors that
have occurred.
In addition to the error codes, the following data is also saved:
Number of times that the error occurred: ( ).
Boiler operating mode ( ).
The flow temperature ( ) and the return temperature ( )
when the error occurred.
To view the error memory, you must first enter the access code .
