Notes
20 Boiler temperature 1, sensor
error
Other Boiler fl ow sensor (B2) is outside normal limits
439 Boiler fl ow sensor (B2) is short-circuit. Check connection for
possible contamination or faulty sensor.
440 Boiler fl ow sensor (B2) is open-circuit. Check connection for
possible contamination or faulty sensor.
26 Common fl ow temperature
sensor error
Any Check connections or replace faulty sensor located on com-
mon fl ow pipe work up stand section (B10)
28 Flue gas temperature, sensor
error
539
543
Flue gas sensor (B8) is short-circuit. Check connection for
possible contamination or faulty sensor.
540
544
Flue gas sensor (B8) is open-circuit. Check connection for
possible contamination or faulty sensor.
40 Return temperature 1, sensor
error
Other Boiler return sensor (B7) is outside normal limits
441 Boiler return sensor (B7) is short-circuit
442 Boiler return sensor (B7) is open-circuit
50 DHW temperature 1, sensor
error
55 Check connections or replace faulty DHW tank sensor (B3)
81 LPB short-circuit or no power
supply
67 LPB Short circuit or no bus power supply. Check external
connections onto the LPB terminals are the not shorted and
the correct polarity. Inspect connections from the GUI to the
Control PCB.
82 LPB address collision 103 LPB address duplicated on another Siemens controlled appli-
ance. Check addresses of all Siemens controlled appliances
via parameter 6600
83 BSB short circuit 595 No BSB communication or wires shorted - Check operation of
GUI or OZW672 (if fi tted)
84 BSB address collision 104 Two appliances connected through BSB (e.g. OZW672) have
the same allocation address. Change one of the appliances
address via parameter 6600
98 Extension module 1, error 605 Indicates that an expansion module can no longer be “seen”
by the controls. To clear this message perform a “Store sen-
sors” (parameter 6200) command, to perform a controls hand-
shake with all connected sensors and ancillaries
NB: When applying power to the heater, this fault message
may appear briefl y, but should self clear within 5 minutes. If
message persists perform a “Store sensors” command
99 Extension module 2, error Any AGU2.5 confi guration error - See also Error 98
100 More than one clock time
master
105 Only one device should be set as the time master, check on
the GUI (parameter 6640) and any OZW672 connected (in
case of connection to an OZW672, this device should be the
master)
102 Clock master without power
reserve
106 The control PCB battery backup for the time clock has been
depleted following the restoration of power to the heater. If this
message has not cleared within 10 minutes of power being
turned on, turn the power off , wait 10 seconds and turn the
power on again. This message does not prevent the operation
of the heater in any way.
105 Maintenance message 87 Item requiring attention but not preventing appliance operation
(e.g. 12 Month service due). Check details of message on the
appliance Front GUI screen.
