Introduction
CORRIGO U-seriesisacompletelynew range of digital controllersdesignedfor
controllingofdistrictheatingsub-stations and boiler stations.Thecontrollershavea
displayandbuiltinpanels for operation andalarmonthefront and are operated by
meansofclearlydefined buttons.
Thecontrollershavebeen designed formountingona DIN rail,innormhousing or on
the front of a cabinet.
The required functions are selected with the help of questions in normal script or by
meansofacode under the configurationmenudependingon the type ofapplication.
CORRIGO U-serieshas temperature sensorinputsfor outgoing radiator-watertempera-
ture,returnwater,room,hot tap-waterand outdoortemperature.
It can control actuators with 0...10 V DC control signal or 3-point floating control
actuators.
Theunitalsohasoutputsforcontrollingcirculationpumpsandinputs for pump
monitoringandsystem-pressurealarmaswellas an external alarm.
CorrigoU20hasayear-base real-time clock, night-setback scheduler,holiday
calendar, holidayperiodsandautomatic normal time/daylightsavingtimechange-
over.
During normal operation, without pressing any buttons, the display also shows the
mostimportantoperatingstatuses such as setpoint/currentvalue,sequence-output
controland time/date/versionetc.
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 can be mounted in standard casing, on a DIN rail in a cabinet or in the front
of a cabinet.
Front mounting kit
When CORRIGO is to be placed in a cabinet front mounting will be facilitated using the
front mounting kit FMK1. The kit contains a front frame with see-through lid and an
integratedmounting-rail.
When placing two CORRIGOs or one CORRIGO and one relay unit RM6..-24/D next to
each other in the front of the cabinet use the FMCR mounting kit. It contains the
samepartsasFMCabove but they areofdifferentdimensions.
Supply voltage
The controller is to be supplied with 24VAC. Terminal 43, system neutral, is
internallyconnectedtoterminal41, signal neutral fortheanalogueoutputs,and
terminals 24, 27, 30 och 33, signal neutral for the analogue inputs.
Inputs
Thecontrollerhascommonpolesfor signal neutral to transmitters (AI1-8)anda
common pole for digital input signals.
Terminal 22 (common for digital input signals) is not the same as signal neutral for
transmitters ( terminals 24,27,30 and 33) and they must not be interconnected.
Signalneutralterminalsfor transmitters(24,27,30and33) are, however,internally
connected and connected to system neutral on terminal 43.
Outputs
Theanalogueoutputsgive0...10 V DC. Signal neutralonterminal41isinternally
connected to system neutral on terminal 43.
Digital outputs are supplied in pairs with 24VAC on the terminals which are marked
with 24VAC in (terminals 6,9 and 12). Each output has an internal triac which gives
24VAC.
Service pin
OntheLON-modelsthecomissioning service pin islocatedbehindamarked opening
on the upper side of the CORRIGO.

When alarms are activated they are displayed in the alarm queue and also as a
blinking red light on the display panel on the front of the controller. Certain alarms
cannotbetracedtoone of the 7LEDsonthepanel and therefore have noseparate

To check the alarm queue press the alarm button . The display will then show
active alarms, the date and time when the alarm became active and the alarm status.
Alarmstatus
Blinking ”AL”indicates that the alarm is active and has not been acknowledged.
Steady ”AL”indicates that the alarm is active but has been acknowledged.
Blinking ”OK”indicates that the alarm has aborted but has not been acknowledged.
Acknowledging an alarm
Alarmsareacknowledgedbymeans of the OKbuttonwhich will remove thealarm
from the alarm list. If the alarms are still active they will remain in the alarm list but
the blinking will be replaced by a steady ”AL”and a steady red light on the alarm

Configuration
Configuration implies the commissioning setting of all the parameters in the CORRIGO.
Parameters are set using script.
Configuration codes
There is also the option of setting parameters by means of two configuration codes.
Thisfunctionisparticularly useful andtime-savingwhena number ofcontrollersare
to be configured in the same way.
The first thing to be shown when the configuration menu is opened is the setting of
thecontrolfunction.
Usingthearrowupbutton the two configurationcodeswillbedisplayed and the arrow
downbuttonwillgivethe parameters oftheotherconfigurationsin script.
Thecodedigitsinthe configuration code correspondtothescriptparameters below
innumericalsequence.This meansthatthefirstdigit in CONFIG.CODE1 determines
which control function the controller is to work with. The second digit refers to heater
type etc.
Before 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.
Tables for configuration code
There is also a special table to facilitate the choice of configuration code. This is
always supplied together with the CORRIGO 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.
Bygoingthroughthe parameters and fillinginthefiguresbeside the respective
selections the configuration code can be obtained without difficulty. This can also act
as a protocol of settings for CORRIGO.
Automatic restart after changing
Whenoneormore parameters havebeenchangedthe controller willrestartwhenthe

Configuration
Some of the functions are not available on all models. This due to that some of the
inputsoroutputs have alternativefunctions.
A. Function sensor AI1
1. Outdoor sensor. Fixed setting. Do not change
Sincetheheatingcontrolisoutdoortemperature dependant this sensor must
beinstalledandconfigured forcorrectfunction.
B. Function sensor AI2
0. --- Input not active
1. HS1Supply.
AI2 must be configured as HS1 Supply if the sequence HS1is to be used for
heatingcontrol.
Thetemperatureatthe sensor is controlledbythecontrolvalve HS1-CV1 so
that the calculated setpoint is obtained. The setpoint depends on the control
curve which is set in the menu ”Control HS1”.
C. Function sensor AI3
0. --- Input not active
1. HS1Roomsensor.
AI3 must be configured as HS1 Room sensor if the sequence HS1is to have
roomtemperaturecompensation.
The sensor signal will displace the control curve to compensate the supply
watertemperaturefor any offsetinroom temperature.

2. HPReturn
The sensor reading is not used in any control-function but only for data
acquisition.
F. Function sensor AI6
0. --- Input not active
1. THWSupply
Must be configured to obtain the THW circuit.
Thetemperatureatthe sensor is controlledbythecontrol valve THW-CV1 so
that the setpoint temperature is held.
The setpoint is set in the menu ”Control HW/THW.

1. HS2Roomsensor.
AI8 must be configured as room sensor if HS2 is to have room compensation.
Function as forAI3, see point C.
2. HS2Return
The sensor reading is not used in any control-function but only for data
acquisition.
