14.1 General

•
If the boiler does not start up, check the
following:
•
Is a 120 V supply present?
•
Is there a heat demand?
•
Has the boiler control (parameter
correctly ?(see section 13.1.3)
If the above items have been verified and the boiler
does not start, this indicates a failure. In the case of a
failure signal, both the code window and the
window will flash. Except for failure
flash).


Important!!
Keep a record of the failure codes before resetting
(numbers, including flashing digits and dots) and quote
them when asking for technical support or consult the
failure code tables in this manual. The failure code is
needed to find the cause of the fault quickly and
correctly. For further details on the various failure
codes and possible causes refer to table 23.

also knows shut-off codes (see section 12.4). In the
latter case only the two dots in the
flash and the code window will display
code may refer to a system problem or incorrect
setting.

14.2 Failure mode (

The latest failure and corresponding operating
codes and applicable temperatures are stored in the
micro-processor memory and can be read out in
failure mode as follows:
-Enter the service code
-Press the

-Select the required step with the

with a flow temperature of 127°F [53°C], return
temperature of 104°F [40°C] and a flue gas
temperature of 136°F [58°C]. The boiler block
temperature was 145°F [63°C], the ionization level was

a speed of 2667 rpm. The time elapsed after the
failure can only be read on a PC or laptop.

In this mode, the fan runs at maximum speed for two°
minutes, which cools down the boiler rapidly. When
this mode is active, the system does not respond to
