21.10.16 SHORT CIRCUIT ON SENSOR E11.T1 FLOW
Function: The alarm is activated when the sensor's value indicates a
temperature higher than 110 °C. The flow temperature T1 becomes
identical to T8. If there are several heat pumps installed, T1 = T8 for the
heat pump that does not produce hot water and has the highest value on
T8. Additional heat mixing valve shut.
Reset condition: The value of the sensor indicates
< 110 °C.
Category: H.
Alarm lamp/buzzer: Yes.
Restart: Automatic once the alarm cause has disappeared.
21.10.17 FAILURE ON SENSOR E12.T1, E13.T1... FLOW
Function: The alarm is activated when the sensor's value indicates a
temperature lower than 0 °C. The mixing valve for the circuit is closed
completely.
Reset condition: The value of the sensor indicates >0 °C.
Category: H.
Alarm lamp/buzzer: Yes.
Restart: Automatic once the alarm cause has disappeared.
21.10.18 SHORT CIRCUIT ON SENSOR E12.T1, E13.T1... FLOW
Function: The alarm is activated when the sensor's value indicates a
temperature higher than 110 °C. The mixing valve for the circuit is
closed completely.
Reset condition: The value of the sensor indicates < 110 °C.
Category: H.
Alarm lamp/buzzer: Yes.
Restart: Automatic once the alarm cause has disappeared.
21.10.19 FAILURE ON SENSOR T2 OUTDOOR
Function: The alarm is activated when the sensor's value indicates a
temperature lower than -50 °C. In the event of a failure on T2, the
outdoor temperature is set to 0 °C.
Reset condition: The value of the sensor indicates
> -50 °C.
Category: H.
Alarm lamp/buzzer: Yes.
Restart: Automatic once the alarm cause has disappeared.
21.10.20 SHORT CIRCUIT ON SENSOR T2 OUTDOOR
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 T2, the
outdoor temperature is set to 0 °C.
Reset condition: The value of the sensor indicates
< 70 °C.
Category: H.
Alarm lamp/buzzer: Yes.
Restart: Automatic once the alarm cause has disappeared.
21.10.21 FAILURE ON SENSOR T3 HOT WATER
Function: The alarm is activated when the sensor's value indicates a
temperature lower than 0 °C. The hot water production is terminated.
Reset condition: The value of the sensor indicates >0 °C.
Category: H.
Alarm lamp/buzzer: Yes.
Restart: Automatic once the alarm cause has disappeared.
21.10.22 SHORT CIRCUIT ON SENSOR T3 HOT WATER
Function: The alarm is activated when the sensor's value indicates a
temperature higher than +110 °C. The hot water production is
terminated.
Reset condition: The value of the sensor indicates < 110 °C.
Category: H.
Alarm lamp/buzzer: Yes.
Restart: Automatic once the alarm cause has disappeared.
21.10.23 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.
21.10.24 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.
21.10.25 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.
21.10.26 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 Chapter 21.10.25).
Reset condition: The value of the sensor indicates
< 110 °C.
Category: H.
Alarm lamp/buzzer: Yes.
Restart: Automatic once the alarm cause has disappeared.
21.10.27 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.
