15 ALARM DESCRIPTION
15.1 Exhaust temperature sensor
damage
This alarm occurs in case of damage of
exhaust temperature sensor and excess of its
measurement range. Upon alarm occurrence,
boiler operation is automatically stopped,
and only CH pump remains in operation.
To reset the alarm - confirm it or switch off
and on the regulator. Check the sensor and
replace, if necessary.
How to check temperature sensor -
see 12.12
15.2 Excess of max. boiler temperature
Protection against boiler overheating
comprises two stages. In first instance i.e.
once the Boiler cooling temperature has been
exceeded, the regulator attempts to reduce
the boiler temperature by discharge of
excessive heat to HUW container and by
opening the mixer servos (only in case the
mixer support = CH On).
Once the temperature measured by HUW
temperature sensor has exceeded the value
set in Max. HUW temp., HUW pump stops in
order to protect the user from burning with
hot utility water. Has the temperature
dropped - the regulator returns to normal
operation. In case the temperature is still
increasing (and has reached 95
 C), power
supply to the fuel feeder and the fan is off
and permanent boiler overheating alarm with
sound signal is produced.
To reset the alarm - switch the power supply
to the regulator off and on.
Note: arrangement of temperature
sensor outside the boiler water
jacket (e.g. at the outlet pipe) is
not recommended because boiler
overheating may be detected with
delay
.
15.3 Excess of max. feeder
temperature
This alarm is produced once the feeder
temperature has exceeded the value set in
the service parameter Max. feeder temp.
If the feeder temperature exceeds this value,
the regulator activates the feeder for a fixed,
set time and the poker. The fan stops and
the pumps start. Once the fuel has been
"pushed out", the regulator stops the feeder
and does not activate it again even though
the feeder temperature remains high.
Alarm may be reset only upon drop of feeder
temperature. To reset the alarm - switch off
and on power supply to the regulator.
Flashback protection function is
inactive when the feeder sensor is
disconnected or damaged.
Flashback protection function is
disabled when power supply to the
regulator is disconnected.
The regulator may not be used as
the only flashback protection of the
boiler. Additional automatic safety
devices should be used.
15.4 Boiler temperature sensor
damage
This alarm occurs in case of boiler
temperature sensor damage and excess of
its measurement range. Upon occurrence of
this alarm, CH, HUW and mixer pumps start
to possibly cool down the boiler.
To reset this alarm - confirm it or switch off
and on power supply to the regulator. Check
the sensor and replace, if necessary

15.5 Feeder temperature sensor
damage
This alarm occurs in case of damage of fuel
feeder temperature sensor and excess of its
measurement range. Upon occurrence of this
alarm, CH and HUW pumps start to possibly
cool down the boiler.
To reset this alarm - confirm it or switch off
and on power supply to the regulator. Check
the sensor and replace, if necessary.

Upon setting of Max. feeder temp.
at '"0", the regulator may operate
without
connected feeder
temperature sensor. However, it is
not a recommended manner of
operation because protection of the
