Corrigo E Heating manual, revision G Chapter 8 Configuration 30
8.5 Twin pump / Single pump
Each heating system can be configured for either a single pump or twin pumps.
When twin pumps are configured, the pumps are alternated weekly on Tuesdays at 10:00 am. On
activation of the pump alarm for the active pump the Corrigo will automatically switch to the other
pump.
Twin/Single pump
HS1: Twin pumps
HS2: Single pump
HS3: Single pump
8.6 Run indication/Motor protection
Inputs are used either for indication of the motor running or for monitoring of motor protection
contacts.
Run indication input should be normally closed. Open contact when the motor is running, i.e. motor
control output is activated, will generate an alarm.
Motor protection should be normally open. Closed contact when the motor is running, i.e. motor
control output is active, will generate an alarm.

8.7 Actuator type
Choose output signals to the actuators connected to the analogue control outputs: 0…10 V DC,
2…10 V DC, 10…0 V DC or 10…2 V DC.
Actuator type
HS1: 0-10V
HS2: 0-10V
HS3: 0-10V
Actuator type
HW1: 0-10V
HW2: 0-10V
Freq: 0-10V
Note that although many manufacturers state 0…10 V DC as control signal, for many actuators the
actual control signal is more often than not 2…10V DC. Check the actuator documentation
carefully. If uncertain, choose 0…10V DC. Although control might be less accurate, it will ensure
that the valve always can be driven to its fully opened and fully closed positions.
8.8 Running time, 3-pos. actuators
These parameters have no function if analogue actuators are configured.
The values are used to determine the control parameters for 3-position actuators.
It is important to set correct values since incorrect values lead to sloppy control.
