AO Analogue outputs
Depending on model, C
ORRIGO
has 3...6 analogue outputs, AO1...AO6.
Output signal 0...10 V DC, 5 mA. Short-circuit protected.
These outputs should refer to terminal 41, signal neutral.
Signal neutral G0, terminal 41, in the C
ORRIGO
is internally connected to sytem
neutral on terminal 43.
It is therefore important that any actuators sharing the C
ORRIGO
supply transformer
are wired with their supply neutral connected to the same transformer pole as the
C
ORRIGO
terminal 43.
AO1...AO3 is present in all models. These outputs comprise the temperature control
sequence. The output function is dependant on the configuration settings but the
actuating order is always Y3 before Y2 before Y1 on increasing heat
demand.
AO1 Y1 - Heating or mixing-dampers.
AO2 Y2 - Heating, Plate exchanger, Rotating exchanger, liquid-connected
exchanger or cooling.
AO3 Y3 - Heating, cooling.
AO4 Output signal for supply-air fan speed control.
Models C20 and C40 only.
AO5 Output signal for exhaust-fan speed control.
Models C20 and C40 only.
AO6 Humidification, dehumidification
Models C30 and C40 only. Function, see page 34.
