Manual C ORRIGO L10 2002-11
CORRIGO L10 for use with air handling systems comes with or without LON
communication option.
L10 Temperature controller for up to three sequences
L10-LON Same as L10 bus also has LON Works communication.
Introduction
COORIGO L10 is a new controller which has been designed to be easy to use and
operate. It has been designed for use in less complex air-handling systems. The
controller has a display and built in indicator on the front for alarm and is operated
by means of clearly defined buttons.
The controller has been designed for mounting on a DIN rail, in norm housing or on
the front of a cabinet.
The required functions are selected with the help of questions in normal script or by
means of a code under the configuration menu depending on the type of application.
The controller has a year-base clock and automatic summer/winter time changeover.
The menu system works with different user-levels to show settings and to allow
settings to be altered. This means that non-technical staff can feel secure while
using the system since it is impossible, on the lower user-levels, to programme
incorrect settings when checking operating status, parameter values, alarms etc.
During normal operation, without pressing any buttons, the display also shows the
most important operating statuses such as setpoint/current value, sequence-output
control and time/date/version etc.
We hope you will be satisfied with your CORRIGO and that it will provide you with
simpler and more economic running of your control systems.

Installation
Corrigo L10 can be mounted on a DIN-rail in a panel or in a panel front.
Panel front assembly kit (See page 2)
When CORRIGO L10 is mounted in a panel front the procedure is made easier by
using the assembly kit FMC. This kit includes front frame in aluminium, support rail,
nuts and bolts. Reversable screw terminals can be ordered (article id: PLTL).
Alternatively FMK1 front mounting kit can be used. It has a transparent cover and
meets the IP54 protection class.
If two CORRIGO L10 are placed adjacent to each other, use the FMCR assembly kit
which is wider. It essentially contains the same things as the FMC kit. Alternatively,
use the FMK2 front mounting kit (has the same properties as FMK1, only wider).
Supply voltage
The L10 is supplied with 24 V AC.
Inputs
The analogue sensor inputs (AI1-4) have a common reference point that is signal
ground. The digital inputs (DI1 - 4) have a common reference point that is not the
same signal as neutral (terminal 19) and must therefore not be tied together.
The signal neutral for analogue inputs and analogue outputs and the system neutral
(terminal 25) are internally connected.
Outputs
Analogue outputs (0...10V) have signal neutral as common reference point, terminal
23. Digital outputs are divided into two categories: Outputs DO1 and DO2 are of triac
type and have a common 24 V AC feed point at terminal 8. Outputs DO3...DO5 are of
relay type and have a common pole at terminal 11.
Wiring
Connects sensors using a shielded twisted-pair wire. The shield should be connected
to the earthrail in the cabinet and left unconnected at the sensor end.

Digital inputs DI
CORRIGO L10 has 4 digital inputs, DI1...DI4 in order to to activate certain functions
and to monitor alarms.
These inputs must only be connected to potential free closing switches.
These inputs should only be closed against the common point DI+ on terminal 7.
Terminal 7 is NOT signal neutral; do not wire together.
DI1 Fan malfunction alarm or Fan status indicator.
- Fan alarm: Intended for use with, for example an overcurrent protection
device. Activates the fan alarm after 2 seconds and stops the system.
- Fan status: Connect to a pressure switch or free contact in the fan motor
relay. In order to activate the controlling outputs on the L10, the DI1
input must be activated within preset delay time. If this does not occur the
system stops and alarm is activated. To check status for more than one fan,
connect the status circuit breakers in series to DI1.
DI2 Water heater pump status.
Must be connected when water heater is used.
Stopped pump interlocks the system.
DI3 Input for status monitoring or alarms. Following functions can be set:
- Extended runtime using timer or pushbutton. Can also be used with presence
detectors.
- Alarm from smoke detectors
- External alarms
DI4 Input for various alarms. Following alarm types can be set:
- Cooler alarm
- Heat exchanger alarm
- Smoke alarm
- External alarm
AI Analogue inputs
CORRIGO L10 has 4 analogue inputs, AI1...AI4.
These inputs are for use with temperature sensors of type Pt1000.
Exception: The AI4 input is used as a digital input when the unit is configured with
overheat protection on an electric heater. In that case, connect this input to a potential free closing contact.
Wire AI-inputs with sensor between respective input and common signal neutral
(terminal 19).
AI1 Outdoor sensor
For example, type TG-R6/Pt1000.
AI2 Room sensor
For example, Ex type TG-R5/Pt1000.
AI3 Supply air sensor
For example, type TG-KH1/Pt1000.
AI4 Frost protection sensor when used with water heater, for example,
type TG-A1/Pt1000 or
overheat protection thermostat when used with electric heater.
Connect this input to a potential free closing switch if configured as overheat
protection input.
Wiring
Manual C ORRIGO L10 2002-11
Digital outputs DO
Corrigo has 5 digital outputs DO1...DO5.
Outputs DO3...DO5 are potential free closing relay contacts, 230V AC, 5A.
Outputs DO1...DO2 are of triac type for use with 24 V AC, 0.5A (1A short duration).
The triac outputs have a common 24V supply pole (see picture in margin).
For use with higher voltages and currents, use external relays.
DO1 Control DX-Cooling stage 1
DO2 Control DX-Cooling stage 2 or external fan control interlock for frost protection.
When used in systems with external fan control and frost protection it is
advisable to interlock fans over this output to ensure that the fans are stopped
in the event of a frost alarm.
DO3 Control fans
DO4 Control pump or electric heater interlock
When the system is configured with electric heater, DO4 is used to interlock
the heater. For example: when a steprelay is used for heating control the heat
will be activated during the cool-off sequence. To prevent this, interlock the
heater via this output (DO4) to ensure that the heater is disconnected from
power during the cool-off period.
When using electric heater the DO4 output is active, except when the system
is idle and during the cool-off period.
DO5 Alarm output.
Analogue outputs AO
CORRIGO L10 has 3 analogue outputs, AO1...AO3.
Outpul levels are 0...10 V DC, 5 mA. Short circuit protected.
Reference point is terminal 23, signal neutral which is internally connected to
terminal 25, system neutral.
The outputs AO1...AO3 make up the temperature controlling sequence. Function for
each output is determined by configuration setting but the order is always
Y3 ? Y2 ? Y1 on increasing heat demand.
AO1 Y1 - Heating or cooling
AO2 Y2 - Cooling, damper, Plate exchanger or rotating exchanger
AO3 Y3 - Cooling

Configuration
CORRIGO-L10 is adapted to the system at hand by selecting functions individually. All
configuration options are set using explanatory menu texts.
Configuration codes
There is also the option of setting parameters by means of two configuration codes.
This function is particularly useful and timesaving when a number of controllers are to
be configured in the same way.
The first thing to be shown when the configuration menu is opened is the setting of
the control function. Using the arrow up button the configuration code will be displayed, and the arrow down button will give the parameters of the other configurations
in plain text.
The code digits in the configuration code correspond to the script parameters below
in numerical sequence. This means that the first digit in CONFIG CODE determines
which control function the controller is to work with. The second digit refers to
sequence etc.
In front of the corresponding selection in the script parameters there is a digit which
corresponds to the code number in the configuration code. See the details below.
Guide for configuration code
There is also a special table to facilitate the choice of configuration code. This is
always supplied together with the CORRIGO L10 instruction sheet.
In the table all the configuration parameters are shown as well as the selections that
can be made. Basic selections are marked in bold type.
By going through the parameters and filling in the appropriate figure for each
selection the configuration code can be obtained without difficulty. This can also act
as a protocol of settings for CORRIGO L10.
Automatic restart after changing
When one or more parameters have been changed the controller will restart when the
user leaves the configuration menu.

Room temperature control with cascade control of the supply air temperature
The temperature sensor Supply air (AI3) controls the sequence so that the setpoint
is reached in the same way as with supply air control. The setpoint for the supply air
temperature is determined by Room sensor (AI2) which, when heating is required,
raises the setpoint for supply air according to the parameters set or, when cooling is
required, lowers the setpoint.
The cascade factor (by how much the setpoint should be changed on a one-degree
deviation from the set room-temperature) is set under ”Settings”, see the appropriate
section.
NOTE: Cascade control is a PI-control with settable I-time (Factory setting 10 minutes) and works with setpoints between set minimum and maximum limitation.
(Current setpoint for supply air temperature is shown in the menu for cascade factor).

Manual C ORRIGO L10 2002-11
Controlling plate heat exchanger
Plate heat exchanger means that the output controls e.g. a damper actuator
to vary the capacity of the heat exchanger.
Defrosting plate heat exchanger
Ice-build up sensor (pressure switch) is connected to DI4. On ice build-up the
defrosting function is activated.
The heat exchanger capacity is set to zero and the heating sequence, Y1 is
used when heating is required. If this is not sufficient to maintain the setpoint
the heat exchanger is permitted to go in with up to 30% of capacity.
The fans continue to operate.
Defrosting will continue until the ice build-up sensor returns to normal, with a
switch-off delay of 10 minutes.
Controlling rotating heat exchanger
Alarm from a rotation sentinel can be connected to input DI4.
CORRIGO L10 can be set to stop the fans on rotation sentinel alarm.
Set under ”Settings”.
D. Frostprotection
0. No
1. Y1
2. Y1 Automatic reset (Reset is performed when the temperature rises to
alarm point plus 5K, with a time delay of
10 minutes)
The alarm limit for the frost protection sentinel is set under ”Settings”.
(Factory setting is 7°C.) The system begins to override the output signal to
the valve when the temperature is 5K higher than the alarm limit. This means
that the temperature when the output begins to be affected is 12°C for the
factory alarm setting of 7°C.
E. Shutdown mode
Controls the heating valve to maintain a preset temperature at the frost
protection sensor when the system is shut down.
Shutdown temperature is set under ”Settings”. (Factory setting, 25°C).
This function is only activated when the pump output (DO3) is active. It means
that when the pumpstop function has been selected, as described in the
paragraph below, the shutdown mode will be deactivated when the pump is
stopped due to warm weather.
0. No
1. Yes
F. Pumpstop
This function requires an outdoor temperature sensor. The circulation pump is
stopped when there is no heating demand (Y1 is less than 1%) and the
outdoor temperature is above a preset temperature. The basic setting is +6°C.
Stop delayed 15 minutes. Can be set under settings. Stopped pump is
exercised 5 minutes every day at 12:00.

Fan alarm: Use this setting when connecting this input to a filter guard or
similar. Activates fan alarm after preset time delay (2 seconds).
Fan status indicator: In order to start the control sequence and activate
the analogue outputs DI1 has to be closed. When the fan control output (DO3)
is activated, Corrigo L10 awaits a status running signal at DI1. If no status
running signal is present at DI1 after a preset delay time, a fan alarm is
activated and the system stops.

K. Function DO1/DO2
When DX cooling is selected, at least one of the outputs Y2 or Y3 must be
configured as cooling control output.
In applications with supply air minimum limiting the minimum limit will be
lowered by a preset amount when the DX-cooling is activated. See under
”Settings”.
DX Binary means that the two outputs are controlled in a binary
sequence: 1, 2, 1+2.
If an outdoor sensor has been configured on AI1, DX-cooling will be blocked
for outdoor temperatures lower than +12°C (fixed value).
When an external fan control switch is used in systems with frost protection,
it is recommended that this breaker is routed via this interlock output. This is
to prevent forced (manual) fan run when the frost alarm is activated.

Adjustment of analogue inputs
The analogue inputs are intended for use with Pt1000 type sensors.
You can also inspect min and max values since last value reset. Refer to menu
branch ”Settings”.
The presented value for inputs AI1...AI4 can be trimmed by ± 2 K when needed.
Make a login at level 3, enter the appropriate input menu for AI1...AI4, press the ?
key and adjust the readout with the up/down arrow keys. When done, press OK.
A filter factor can be applied if values appear unstable. Refer to menu branch
”Settings”.
NOTE: CORRIGO L10 is always factory calibrated with respect to analogue inputs.
Adjustments are therefore normally not necessary.
There is a rare possibility that f.ex. long wires cause erroneous readout. When in
doubt, measure the controlling value at the sensor with an accurate and calibrated
instrument under stable conditions to eliminate any faulty sensor.
Min/Max viewing of temperature values
The four analogue inputs for temperature can keep track of the min/max temperature
since the last reset was made. The ”Settings” section have a menu for activation of
this option ”SHOW MIN/MAX”.
To reset the min/max values, press the ? button and then the OK button. The minand maxvalue will be set to the current measured value.
Filtering - analogue inputs
The analogue inputs are factory set with a filter factor of 1. This feature is used to
suppress noise and hum that is introduced into the sensor circuits. The filter factor
can be increased, but use caution so that the factor for the controlling sensor is not
set too high so that it may jeopardize the control function.

Scheduler
CORRIGO L10 has a scheduler based on a one-week period. This means that the days
of the week can be individually selected or deselected in the period. The scheduler
can handle power losses for at least 24 hours without loss of data.
1. Clock. Change requires user level 1.
The first menu manages current date, time and weekday.
3. Period 1, 2, 3 Change requires user level 2.
CORRIGO L10 has 3 period settings for the weekly program.
To change. press the ? key. By pressing the up/down arrow keys the
weekday at the cursor is toggled in and out of the period program. When day
has been selected/deselected, press the OK key to confirm setting for this day
and advance the cursor to the next day. Repeat this procedure for the remaining
days in the period.
The time-of-day entries determine start and stop times. The one at the upper
row is start time and the one at the lower row is stop time.
If other times of day for start and stop than those for period 1 iare required for
some weekdays, set this using period 2 and 3 if needed.
If 24 hours continous run is desired, set both start and stop times to 00:00.
Example: The system should run Mo - Fri 07:00-17:00 and Sat 08:00-13:00
Solution: Set period 1 to: and period 2 to:
External scheduler
If an external scheduler is used, disable all weekday entries in all periods such
as described in the menu frame below.
3. Daylight saving time toggling
The scheduler normally works with automatic daylight saving time (DST)
adjustment i the spring and in the autumn in accordance with the European
DST rules.
Spring: Current time is advanced 1 hour at 02:00 last Sunday in March.
Autumn: Current time is set back 1 hour at 03:00 last Sunday in October.
If automatic DST adjustment is not required set this configuration option

30.Blocking conditions for alarm output
The alarm output can be blocked during certain times of day/week so that alarms
are not forwarded during these periods (for example: night time and weekends).
Important alarms however, such as frostprotection, overheat protection and smoke
alarms always activates the alarm output and will not be affected by this setting.
Time period and days for which to allow all alarms to be forwarded is set in this
menu.
Example: Alarms are only allowed to activate the alarm output Monday to Friday
between 08:00 - 17:00. The setting would be as follows:
NOTE: Even if the alarm output is being blocked the alarm is registered and
placed in alarm queue and the indicator on the front will flash as normal.
31.Stop system on malfunctioning rotating exchanger
If a rotating heat exchanger malfunctions and causes alarm, the system can be
stopped to prevent running with too low temperature. A malfunctioning exchanger
can cause increasing heating costs which can be avoided by stopping the system
when DI4 is activated.
Set to ”Yes” to stop system to stop the fans when alarm from exchanger is
present.
This function is only relevant when rotating exchanger is configured.
