Corrigo ventilation 3.4 manu

Manual Corrigo Ventilation, revision R Chapter 17 Configuration 93
17.20 Enthalpy control
Cooling recovery
run when enthalpy is
greater outd than
indoors : Active
For a detailed description, see section 5.1.8 Enthalpy control.
17.21 External setpoint
An external setpoint device, for example TBI-PT1000 or TG-R4/PT1000 can be connected. The
setpoint device must follow the PT1000 resistance curve. The setting range can be restricted.
External setpoint
Not active
Min setp: 12.0°C
Max setp: 30.0°C
For details, see section 5.1.10 External setpoint.
17.22 Run indication / Motor protection
Digital input signals are used to supervise fans and pumps. They can be configured either for
indication of the motor running or for monitoring of motor protection contacts.
An input configured for run indication should normally be closed during operation.
Open input when the motor is running, i.e. motor control output is activated, will generate an alarm.
For supply air fans and extract air fans, there is also a conflict alarm, i. e. an alarm if the run
indication input is closed even though the motor control output is not activated. See alarm 33
Supply Air Fan external operation and alarm 34 Extract Air Fan external operation in the section
Alarm configuration.
An input configured as motor protection should be normally open, i. e. closed contact when the
motor is running, i.e. motor control output is activated, will generate an alarm.

When running frequency controlled fans, the pressure signal from each respective fan’s pressure
transmitter is normally used as run indication signal. If the pressure falls below the set value during
normal operation, a malfunction alarm is activated.
Min pressure for
run indication
SAF: 25.0 Pa
EAF: 25.0 Pa
