ALARMS
Category: H.
Alarm lamp/buzzer: Yes.
Restart: Automatic once the alarm cause has disappeared.
21.10.28 SHORT CIRCUIT ON SENSOR E2X.T9 HEAT TRANSFER
FLUID IN
Function: Activated when the sensor's value indicates a temperature
higher than 110 °C. T9 is calculated according to the following formula:
T9 = T8 - Compressor x 7K + 0.07K x current output in operation.
Reset condition: The value of the sensor indicates
< 110 °C.
Category: H.
Alarm lamp/buzzer: Yes.
Restart: Automatic once the alarm cause has disappeared.
21.10.29 FAILURE ON SENSOR E2X.T10
Function: Activated when the sensor's resistance value indicates a
temperature lower than -20 °C. In the event of a failure, T10 is set at a
temperature calculated according to the following formula: T10 = T11 +
Compressor x 3K.
Reset condition: The value of the sensor indicates
> -20 °C.
Category: H.
Alarm lamp/buzzer: Yes.
Restart: Automatic once the alarm cause has disappeared.
21.10.30 SHORT CIRCUIT ON SENSOR E2X.T10
Function: Activated when the sensor's value indicates a temperature
higher than 70 °C. In the event of a short circuit, T10 is set to an
estimated temperature using this formula:
T10 = T11 + Compressor x 3K.
Reset requirement: The value of the sensor indicates >70 °C.
Category: H.
Alarm lamp/buzzer: Yes.
Restart: Automatic once the alarm cause has disappeared.
21.10.31 FAILURE ON SENSOR E2X.T11
Function: Activated when the sensor's value indicates a temperature
lower than -50 °C. In the event of a failure, T11 is set at a temperature
calculated according to the following formula: T11 = T10 - Compressor
x 3K.
Reset condition: The value of the sensor indicates
> -50 °C.
Category: H.
Alarm lamp/buzzer: Yes.
Restart: Automatic once the alarm cause has disappeared.
21.10.32 SHORT CIRCUIT ON SENSOR E2X.T11
Function: Activated when the sensor's value indicates a temperature
higher than 70 °C. In the event of a short circuit, T11 is set to an
estimated temperature using formula:
T11 = T10 - Compressor x 3K.
Reset requirement: The value of the sensor indicates >70 °C.
Category: H.
Alarm lamp/buzzer: Yes.
Restart: Automatic once the alarm cause has disappeared.
21.10.33 ADDITIONAL HEAT IS NOW WORKING AT ITS HIGHEST
TEMPERATURE
Function: The electric additional heat begins to be stepped down. The
warning is activated in additional heat mode if the sensor T8 approaches
62
the highest temperature permitted for T8. The warning is blocked during
hot water peaks or extra hot water.
Reset condition: The warning is deactivated when the sensor
temperature falls sufficiently.
Category: K.
Alarm lamp/buzzer: No.
Restart: Automatic once the alarm cause has disappeared.
21.10.34 ELECTRIC ADDITIONAL HEAT SHUT DOWN DUE TO HIGH
TEMPERATURE E2X.T8
Function: The electric heater is turned off. The warning is activated in
additional heat mode if the sensor T8 exceeds 80 °C.
Reset condition: The warning is deactivated when T8 falls below 76 °C.
Category: K.
Alarm lamp/buzzer: No.
Restart: Automatic once the alarm cause has disappeared.
21.10.35 HIGH TEMPERATURE DIFFERENCE HEAT TRANSFER
FLUID E2X
Function: The warning is activated when the difference between sensor
E2x.T8 and E2x.T9 exceeds 13K. 10 min after compressor start and
change of production mode, the temperature difference is measured
and if it is too big, the warning is given after a delay of 3 min. The warning
is not given when the compressor is inactive or when additional heat is
allowed.
Reset condition: The warning does not shut down any function but is
registered in the alarm log.
Category: L.
Alarm lamp/buzzer: No.
Restart: Deactivated on acknowledgement of the warning display.
21.10.36 HIGH TEMPERATURE DIFFERENCE COLLECTOR CIRCUIT
E2X
Function: The warning is activated when the difference between sensor
E2x.T10 and E2x.T11 exceeds 6K. 30 min after compressor start and
change of production mode, the temperature difference is measured
and if it is too big, the warning is given after a delay of 15 min. The
warning is not given when the compressor is inactive.
Reset condition: The warning does not shut down any function but is
registered in the alarm log.
Category: L.
Alarm lamp/buzzer: No.
Restart: Deactivated on acknowledgement of the warning display.
21.10.37 SCREED DRYING SET POINT VALUE FOR HEATING NOT
REACHED
Function: Activated when the set point value for a drying step has not
been reached.
Reset condition: The warning is deactivated on acknowledgement of
the warning display.
Category: L.
Alarm lamp/buzzer: No.
Restart: The warning does not shut down anything, the drying program
continues with the following step.
21.10.38 THE HEAT PUMP IS NOW WORKING IN ANTI-FREEZE
MODE
Function: Activated when the flow temperature of a circuit falls below
8 °C and the 10-min timer has counted down.
Reset condition: The circuit's flow temperature exceeds 25 °C.
Category: L.
