Corrigo E Heating manual, revision G Chapter 5 Functional description 20
5.6.2 Alarms
Pulse error If no pulses are detected within a settable time an alarm is activated. Setting
the time to 0 inhibits the alarm function.
High usage If the daily usage is higher than a settable value an alarm is activated.
Leakage control If the lowest hourly usage during the previous day is higher than a settable
value an alarm is activated.
5.7 Energy monitoring
One digital pulse function can be configured for heating energy monitoring. The pulse constant is
settable.
5.7.1 Usage values
The following usage values are calculated:
• 24 hour usage in kWh, today
• 24 hour usage in kWh, yesterday
• 24 hour usage in kWh, day before yesterday
• Total usage in kWh or MWh. The value is resettable
5.7.2 Power values
Heating power is calculated by measuring the time between the energy pulses. The following power
values are calculated:
• Instantaneous value for a certain time or after a certain number of pulses
• Average of the above instantaneous value for the last hour
• Maximum value for the above instantaneous value
5.7.3 Leakage monitoring
Once a week, the control valves will be closed and the energy usage measured for a preset time. An
alarm is generated if the energy leakage is larger than a settable value, default 3000 W. The time for
and duration of the leakage monitoring is settable. Default is Sundays at 2:00 am for 30 minutes.
5.7.4 Alarms
Pulse error If no pulses are detected within a settable time an alarm is activated. Setting
the time to 0 inhibits the alarm function.
High usage If the daily usage is higher than a settable value an alarm is activated.
5.8 Electricity meter
One digital pulse function can be configured for electricity energy monitoring. The pulse constant is
settable.
5.8.1 Usage values
Total usage in MWh. The value is resettable.
