Boiler overview

1

Operating condition and information.
A description of the operating conditions can be
found in the integrated Help menu by pressing the

 button.

2

Boiler temperature

3

Boiler consumers.
Currently, the consumer is charged by the burner
at a flow temperature of 64 °C.

4

Enabling or locking the boiler.

 = burner is enabled
 = burner is locked

5

[Settings] button.
In this menu, the standby time of the burner can be
adjusted.

Enabling or locking the boiler

This allows the burner for the ETA
control system to be enabled or

disabled. If the burner is enabled (

 setting),

the ETA control system can activate it when needed,
but only within the configured times of operation. In the

 setting, the auxiliary boiler is locked and the

ETA control system cannot put the burner into
operation.

Various tasks of the auxiliary boiler

An additional burner (oil or gas) in the heating system
serves either to cover peak loads in the heating
system, or as fail-safe for the main heat producer (for
example: boiler or another buffer).

Auxiliary boiler to cover peak loads:

•

This auxiliary boiler has a separate charging pump
and can supply the consumer (e.g. buffer) with
heat at the same time as the main heat producer
(e.g. boiler).

In heating systems with a buffer, the burner is only
put into operation if the buffer requests a capacity
that is higher than that of the ETA heating boiler.
For heating systems without a buffer, the burner is
only put into operation when the ETA heating boiler
does not reach the required output.

The burner charge pump is started by the ETA
control system if the burner temperature is higher
than the enabling temperature of the charging
pump [Enable AuxBoilChargePump]. In addition,
the auxiliary boiler temperature must be greater
than the temperature of the consumer to be
charged by at least the configured [Thermostat
diff.] difference.

Aux. boiler as fail-safe for the main heat producer:

•

Through the changeover valve between main heat
producer and aux. boiler, the consumers are
supplied either by the main heat producer or the
aux. boiler. If the main heat producer is switched
off or a malfunction is present, the changeover
valve changes to the aux. boiler to meet the heat
requirements of the consumer.

Switching from one heat producer to another only
happens when the temperature of the auxiliary
boiler exceeds the configured enabling
temperature [Enable diverter valve] of the
changeover valve. Only then does the changeover
valve route the heat from the hotter heat producer
to the consumers.
