Operating Modes - Siemens DG30025 Assembly And Operating Instructions Manual

Wall Assembly (page II, diagrams 3 to 10)
The assembly diagram is on the packaging. To allow for replacement of the heating flange and anti-corrosion anode, at least
350m of free space must be left underneath the reservoir. Use appropriate screws with a diameter of at least 12mm. Provide a
special supporting structure for lightweight walls.
Unlock the safety bar (2) (shift the bar on the left e pull it down) remove the bracket. Pass the power line in its housing (3).
Once mounted the appliance on the wall relock the bar 2.
Water Connection (page III, diagrams 11)
Only detachable connections are permissible!
Before connecting the fittings, thoroughly flush out the water pipes in order to remove any impurities.
It is normal for water to trickle from the pressure safety device during the heating phase; for this reason, it is necessary to
connect the outlet, which must always be left exposed to the atmosphere, to a drainage pipe that slopes downwards and
located in an area not subject to ice.

Operating Modes

Single Power Operation
Connection without off-peak contact.
The appliance heats with the adjusted performance.
The 'fast-heating' button is only used for the reset and diagnose functions.
Connection with off-peak contact
If the 'fast-heating' button is activated, the device heats once to the configured temperature. Afterwards, the device turns
itself off automatically.
Double Power Operation
Connection without off-peak contact.
The reservoir heats with the configured basic performance.
The "fast-heating function" activates a heating cycle at higher installed power in order to accelerate the heating-up procedure.
To start this function, press the fast-heat button . The LED fast-heating' lights up. The function turns itself off
automatically, as soon as the configured temperature has been reached. The LED 'fast-heating' turns off .
Connection with off-peak contact
During off-peak time the device heats with the configured basic performance. The "fast-heating function" activates a heating
cycle at higher power in order to accelerate the heating-up procedure. To start this function, press the fast-heat button .
The LED 'fast-heating' lights up. The function turns itself off again automatically as soon as the configured temperature
has been reached. The LED fast-heating' turns off.
The rest of the time, the device does not heat. If the 'fast-heating' button is activated, the device heats once to the con-
figured temperature. Afterwards, the device turns itself off automatically.
Boiler Mode
Connection without off-peak contact.
The device does not heat by default.
If the 'fast-heating' button is activated, the device heats once to the configured temperature. Afterwards, the device turns
itself off automatically.
Each further heating process must be started by pushing the button "fast-heating" .
Electrical Connections
Danger of electric shock!
The power switch "S1" may only be activated in an unpowered state!!
Remove lower cap by taking the screws out (page V, diagram 15, 15.1, 15.2, 15.3).
