Alarm due to failure of temperature probes
Should the temperature probes malfunction, the boiler shutdown symbol
is displayed and the following codes may flash:
- E05, CH probe: the boiler does not.
- E06, DHW probe (only KC model): the boiler only operates in CH mode, not DHW mode.
- E1, storage probe (only KR model with optional external boiler and NTC temperature probe: 10 kΩ @ ß=3435): the boiler operates in
CH, while DHW production is disabled.

Flow alarm
Should flow temperature rise above 85 °C, the burner is turned off.
Normal boiler operation will be restored once flow temperature decreases below 85 °C.
2.5.8
Alarm due to external probe malfunction
If the (optional) external temperature probe malfunctions, the boiler shutdown symbol
is displayed and
code E3 flashes.
The boiler will continue to operate, but the sliding temperature function is deactivated. The temperature
of the CH water is regulated according to the position of regulator
4
(pic. 1), which in this case loses its
function as a virtual ambient temperature regulator (see .4.6.).

Notes for the user
The user may only access boiler parts that can be reached without using technical equipment and/or tools: the user is not
authorized to remove boiler casing and operate on any internal part.
No one, including qualified personnel, is authorized to modify the boiler.
The manufacturer shall not be held responsible for damage to people, animals, or property due to tampering or improper
intervention to the boiler.
Should the boiler be left inactive for a long time and power main supply disconnected, the pump might need to be un-blocked.
Such servicing includes boiler casing removal and access to boiler internal parts, therefore only qualified personnel may per-
form it. Pump blockage may be avoided by adding inhibitor suitable for multi-metal systems to water.
