INSTRUCTION
Mount the controller on a DIN-rail in a panel or in a
seperate casing.
If installed in a panel front, use assembly kit FMC.
Protection class
IP20
Ambient temperature
0...50ºC
Installation
Wiring
Supply voltage - Terminal 24...26
Terminals for supply 24V AC, system neutral och
protective earth.
Analogue inputs AI1...AI4 - Plint 15...19
Use Pt1000 type sensors. The usage for each sensor
is determined by the selected controller options. Use
the table on the left (Fig. 1) for quick reference to
determine sensor usage. Connect selected sensors
according to the list.
N.B.
All AI inputs must refer to the common terminal for
these inputs (terminal 19). This terminal may not be
connected to any other terminals in the system.
AI1
is used, depending on configuration, either for:
1. Outdoor temperature.
2. External setpoint - input for setpoint signal.
These function are mutually exclusive. Only one of them
can be selected at a time.

ORRIGO
L10 is a less complex digital controller
compared to the C10 model. This controller is
intended for use with air-handling systems and has a
simple easy-to-learn user interface. It also comes
with many system options to ensure flexibility.
C
ORRIGO
L10 controls temperature in up to three
sequences which are configurables as either heat,
cool, damper, plate heat-exchanger or rotating heat-
exchanger. Different types of controlling functions can
be selected including supply air control with or without
compensation or zone/room control with or without
cascade function. In addition to the basic control
features it has a number of abilities such as DX-
cooling in one or two stages, controlling and monitoring
fans and pumps, alarm handling, etc.
C
ORRIGO
L10 has a real-time clock with battery backup,
weekly timing period and automatic setting/resetting of
daylight saving time periods.
L10 is also available with a LON communication option
(model L10-LON).
Sensors...
AI2
is used for zone/room temperature in some control-
ler configurations.
AI3
is used for supply air temperature in some control-
ler configurations.
AI4
is used, depending on configuration, either for:
1. Frost protection in systems with water heater. If
shutdown mode is selected, L10 uses this input as
control value when the fans are stopped.
2. Overheat protection in systems with electric heater. In
this case it should be connected to a potential free
closing switch.
Digital inputs DI1...DI4 - Plint 3..7
The digital inputs are activated by closing switch
against terminal 7 (DI+).
N.B.
This terminal must not be wired together with other
signal and/or system neutrals in the system but only as
reference point to DI1...DI4.
Reference voltage 24V AC.
DI1 Pressure switch / fan run indicator
or
Fan overload protector.
DI2 Pump run indicator
DI3 Extended run (timer/pushbutton/presence)
or
smoke alarm
or
external alarm.
DI4 Alarm for: chiller, heat exchanger, smoke detector
or
external alarm.
Analogue outputs
0...10V DC outputs AO1...AO3 - Terminal 20...23
Signal 0...10V DC, 5mA.
AO1
Control output Y1
AO2
Control output Y2
AO3
Control output Y3
These outputs must refer to terminal 23, which is
signal neutral.
N.B.
In C
ORRIGO
L10 this terminal is
internally connected to system neutral.
The functions of the outputs depend on the current
control configuration but the sequence order is always
