16.9.28 Failure on sensor E1x.TT.T5 room
Function: The alarm is activated when the sensor's value
indicates a temperature lower than -1 °C. In the event of
a failure on sensor T5, the room temperature influence
is set to 0.
Reset condition: The value of the sensor indicates
> -1 °C.
Category: H.
Alarm lamp/buzzer: Yes.
Restart: Automatic once the alarm cause has
disappeared.
16.9.29 Short circuit on sensor E1x.TT.T5 room
Function: The alarm is activated when the sensor's value
indicates a temperature higher than +70 °C. In the event
of a short circuit on sensor T5, the room temperature
influence is set to 0.
Reset condition: The value of the sensor indicates
< 70 °C.
Category: H.
Alarm lamp/buzzer: Yes.
Restart: Automatic once the alarm cause has
disappeared.
16.9.30 Failure on sensor E31.TT.T5 room
Function: The alarm is activated when the sensor's value
indicates a temperature lower than -1 °C. In the event of
a failure on sensor T5, the room temperature influence
is set to 0.
Reset condition: The value of the sensor indicates
> -1 °C.
Category: H.
Alarm lamp/buzzer: Yes.
Restart: Automatic once the alarm cause has
disappeared.
16.9.31 Short circuit on sensor E31.TT.T5 room
Function: The alarm is activated when the sensor's value
indicates a temperature higher than +70 °C. In the event
of a short circuit on sensor T5, the room temperature
influence is set to 0.
Reset condition: The value of the sensor indicates
< 70 °C.
Category: H.
Alarm lamp/buzzer: Yes.
Restart: Automatic once the alarm cause has
disappeared.
16.9.32 Failure on sensor E2x.T8 heat transfer fluid out
Function: Activated when the sensor's value indicates a
temperature lower than 0 °C. To be able to make hot
water, T8 is set at a temperature calculated according to
the following formula: T8 = T9 + Compressor x 7K + 0.07K
x current output in operation.
The active compressor provides Compressor = 1 and
current output in operation means additional heat in %.
Compressor operation and 50% additional heat then
give T8 = T9 + 10.5K. Compressor off (Compressor = 0)
and no additional heat (0%) give T8 = T9.
Reset condition: The value of the sensor indicates >0 °C.
Category: H.
Alarm lamp/buzzer: Yes.
Restart: Automatic once the alarm cause has
disappeared.
16.9.33 Short circuit on sensor E2x.T8 heat transfer
fluid out
Function: Activated when the sensor's value indicates a
temperature higher than 110 °C. T8 is calculated
according to the same formula as in the event of a failure
Æ Chapter 16.9.32).
Reset condition: The value of the sensor indicates
< 110 °C.
Category: H.
Alarm lamp/buzzer: Yes.
Restart: Automatic once the alarm cause has
disappeared.
16.9.34 Failure on sensor E2x.T9 heat transfer fluid in
Function: Activated when the sensor's value indicates a
temperature lower than 0 °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 >0 °C.
Category: H.
Alarm lamp/buzzer: Yes.
Restart: Automatic once the alarm cause has
disappeared.
