DI Digital inputs
DI1 Filter guard (s) (Pressure switch monitoring the pressure drop across a filter)
If there are several filter guards they should be wired in parallel
DI2 Run indication for water circulation pump
Must be connected when water heating is used. Pump standstill will prevent
the system from running
DI3 Alarm input from chiller (-s)
DI4 Rotation sentinel or heat exchanger ice build-up sentinel
DI5 Fire alarm
DI6 External alarm, external switches ”not in Auto position” or end position
switches in fire dampers (for fire damper exercising)
DI7 Pushbutton or timer for extended running at normal speed
DI8 Pushbutton or timer for extended running at reduced speed
AO Analogue outputs
In this menu the current configurations and outputs for the analogue outputs are
shown. The outputs are shown both in V DC and in %.
AO1 Y1 - Heating, cooling or mixing dampers
AO2 Y2 - Heating, plate exchanger, rotating exchanger, liquid connected
exchanger or cooling
AO3 Y3 - Heating or cooling
AO4 Output signal for supply air fan pressure control (C20 and C40 only)
AO5 Output signal for exhaust air fan pressure control (C20 and C40 only)
AO6 HumidIfication or dehumidification (C30 and C40 only)
The outputs AO1....AO3 can also be set to -, indicating that they are not in use.
DO Digital outputs
DO1 Start supply-air fan (High speed for 2-speed fan in C10 and C30).
DO2 Start exhaust-air fan (High speed for 2-speed fan in C10 and C30).
DO3 Control of circulation pump or electric heating interlock.
Must be wired when water heater is used. Stopped pump will force the
C
ORRIGO
to shut-down mode.
DO4 Control of chiller 1 (DX1) or
Start supply-air fan, low speed for 2-speed control in C10 and C30.
DO5 Control of chiller 2 (DX2) or
Start exhaust-air fan, low speed for 2-speed control in C10 and C30.
DO6 External frost protection interlock or fire damper exercising.
Function see page 36, Function DI6/DO6.
DO7 Alarm output relay
