CORRIGO VENTILATION 3.6 MANU

Manual Corrigo Ventilation, revision V Chapter 17 Configuration 95
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
Alarm from frequency converter
When running frequency controlled fans, you sometimes want to use both a pressure signal from a
pressure transmitter and a digital alarm signal from a frequency converter. An analogue input for a
pressure transmitter and a digital input for "SAF Indication" or "EAF Indication" must then be
configured. The setting "Run indication/Motor protection SAF" or "EAF Indication" must be set to
"Motor protection". A fan alarm will be activated both when there is no pressure signal from the
pressure transmitter, and when the digital signal "SAF Indication" or "EAF Indication" is activated.
