Operating Modes - Siemens DG15025 Assembly And Operating Instructions Manual

BZ12411 wall temperature regulator with bath spout, shower hose and hand sprinkler; or BZ11114 wall regulator with shower
hose and hand sprinkler. The discharge from the fitting must always be free. Never use an aerator! A back-flow preventer is to
be installed in the cold water intake.
Wall Assembly (page II, diagrams 6 to 9)
The assembly diagram is on the packaging. To allow for replacement of the heating flange and anti-corrosion anode, at least
500m 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.
Mount DG120 and DG150 with both mounting brackets. Vertically align DG80 and DG100 with the wall separator C.
Water Connection (page III / IV, diagrams 10 to 12)
Only detachable connections are permissible!
Before connecting the fittings, thoroughly flush out the water pipes in order to remove any impurities.
For closed operations, if the safety valve is not directly above the drain, then the drain pipe must be mounted at a continuous
downward slope in a frost-free environment.
Please take care because of application range within water types according to technical data on page 17.

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. All 6 LED thermal capacity
indicators light up as soon as the configured temperature has been reached. 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 auto-
matically, as the 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 config-
ured temperature. All 6 LED thermal capacity indicators light up as soon as the configured temperature has been reached.
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. All 6 LED thermal capacity
indicators light up as soon as the configured temperature has been reached. 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!!
