2 Introduction COORIGO is a completely new range of controllers which has been designed to be easy to use and operate. The controllers have a display and built in panels for operation and alarm on the front and are operated by means of clearly defined buttons. The controllers have 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.

9 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 integrated mounting-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 same parts as FMC above but they are of different dimensions. Supply voltage The controller is to be supplied with 24V AC. Terminal 43, system neutral, is internally connected to terminal 41, signal neutral for the analogue outputs, and terminals 24, 27, 30 och 33, signal neutral for the analogue inputs. Inputs The controller has common poles for signal neutral to transmitters (AI 1-8) and a 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. Signal neutral terminals for transmitters (24,27,30 and 33) are, however, internally connected and connected to system neutral on terminal 43. Outputs The analogue outputs give V DC. Signal neutral on terminal 41 is internally connected to system neutral on terminal 43. Important! Digital outputs are supplied in pairs with 24V AC on the terminals which are marked with 24V AC in (terminals 6,9 and 12). Each output has an internal triac which gives 24V AC. Terminals 6, 9 and 12 are also internally connected. Service pin On the LON-models the comissioning service pin is located behind a marked opening on the upper side of the CORRIGO.

14 AI Analogue in CORRIGO has 8 analogue inputs, AI1...AI8 The function of some of the inputs varies depending on the choice of model and configuration. PT1000 type temperature sensors must be used on those inputs that are configured as temperature inputs. In certain cases an AI-input may be used as a digital input. It must then be connected to a voltage-free, closing contact. When active input signals are connected they must be V DC. AI-inputs must always use the signal neutral of the AI terminal block as reference. (terminals 24, 27, 30 or 33). AI1 and AI2 are used for connecting pressure switches/transmitters for monitoring and control of the supply air and exhaust air fans Note: These signals control vital functions in the CORRIGO. They must always be connected for correct control function. C10 and C30 Connect the inputs to pressure switches with voltage-free closing contacts, for example DTV, or to voltage-free closing contacts in the fan-motor relays. C20 and C40 Connect the inputs to pressure transmitters with a V DC output, for example DMD or DTL. Wiring, see example in the margin. The transmitter pressure range is set in the menu Settings, see page 42. AI3 och AI4 C10 and C20 AI3 Used for exhaust air temperature sensor, for example TG-K3/PT1000. AI4 Used for extract air temperature sensor or for minimum limiting sensor in the heat exhanger circuit when using a liquid connected heat exchanger. (See page 28). These functions are mutually exclusive, only one of them may be chosen. C30 and C40 AI3 Used for room humidity transmitter, for example HRT. AI4 Used for duct humidity sensor (limiting sensor), for example HDT3200. The sensors must have an output signal of V DC corresponding to % RH. Since neither of the supply voltage terminals is connected to the AI signal neutral it is necessary to make an external connection between the supply voltage pole chosen as G0 and the AI signal neutral. Note: If no limiting sensor is connected AI4 must be connected to signal neutral. AI5...AI8 AI5 Outdoor temperature sensor, for example TG-R6/PT1000. AI6 Supply air temperature sensor, for example TG-K3/PT1000. AI7 Room temperature sensor, for example TG-R5/PT1000. AI8 Frost protection sensor, for example TG-A1/PT1000 when the unit is configures for water heating. Input for high temperature limiting switch when the controller is configured for electric heating. Connect to voltage-free closing contact. (See page 27) 15

15 DI Digital inputs CORRIGO has 8 digital inputs, DI1...DI8 for activation of certain functions and input of external alarm signals. These inputs may only be wired to voltage-free contacts. These inputs may only refer to the common DI pole on terminal 22. Terminal 22 does not have the same potential as other signal neutrals in the CORRIGO and may not be connected to any other terminals except the DI inputs. Each input can be individually set, either so that closed contact activates the function/alarm, or so that open contact activates the function/alarm. See under menu Settings page 43. Important! DI1 DI2 DI3 DI4 DI5 DI6 DI7 DI8 Input for filter monitor pressure switch(es). If there are several switches these should be wired in parallell. Circulation pump indication. Must be wired when CORRIGO is configured for water heating. A stopped pump will force the controller to go into shut down mode. Alarm from cooling machine(s). Rotation sentinel or ice build-up thermostat in plate exchanger. Fire alarm. External alarms or external switches not in Auto position (used when CORRIGO is used with relay module RM6H-24/D or fire damper end position switches (for fire damper exercising). Function depends on configuration settings (see page 30). Pushbutton or timer for extended running, single speed fan or high speed when using two-speed fans. Pushbutton or timer for extended running, low speed when using two-speed fans. Simultaneous closure of both DI7 and DI8 will force the CORRIGO to shut down. For installations with external switches for fan control, wire according to the figures below. DI7 and DI8 should then be configured as for timer. See page 31. H 0 Auto DI7 High speed Low speed 0 Auto DI7 DI8 DI8 single-speed fans 2-speed fans 16

16 AO Analogue outputs Depending on model, CORRIGO has analogue outputs, AO1...AO6. Output signal V DC, 5 ma. Short-circuit protected. These outputs should refer to terminal 41, signal neutral. Signal neutral G0, terminal 41, in the CORRIGO is internally connected to sytem neutral on terminal 43. It is therefore important that any actuators sharing the CORRIGO supply transformer are wired with their supply neutral connected to the same transformer pole as the CORRIGO 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

17 DO Digital outputs CORRIGO has 7 digital outputs DO1...DO7. DO7, alarm output is a voltage free closing relay contact. 1 A, 24 V AC/DC. The outputs DO1...DO6 are triac controlled, 0.5 A, 24 V AC. Short term 1 A. The triac outputs are paired to common supply terminals for 24 V AC. DO6 out See figure in the margin. 24 V AC in For handling higher voltages or currents, use relay modules RM6-24/D or DO5 out RM6H-24/D that have been developed for this purpose. Some of the outputs have alternative functions depending on model and configuration. For example, this means that, in C10 and C30, DX cooling cannot be combined with control of two-speed fans DO1 DO2 DO3 DO4 DO5 DO6 DO7 Start supply-air fan (High speed for 2-speed fan in C10 and C30). Start exhaust-air fan (High speed for 2-speed fan in C10 and C30). Control of circulation pump or electric heating interlock. Must be wired when water heater is used. Stopped pump will force the CORRIGO to shut-down mode. DO3 is normally used for control of the circulation pump. When using electric heating, this is not used. Instead it can often be useful with an output for electric heating interlock, for example when a step-controller is used to control the heater. Step-controllers often have step-up/step-down time delay functions. This can lead to heating output during the cool-down period or even after the supply air fan has been shut down which will trip the heater high-limit thermostat. By wiring the heating relays via DO3 the heating output will be shut down as soon as CORRIGO switches from running mode to shutdown mode. When CORRIGO is configured for electric heating DO3 will be active during normal running mode and switched off in shut-down mode i.e. even during the cool-down period. Control of chiller 1 (DX1) or Start supply-air fan, low speed for 2-speed control in C10 and C30. Control of chiller 2 (DX2) or Start exhaust-air fan, low speed for 2-speed control in C10 and C30. External frost protection interlock or fire damper exercising. Function see page 30, Function DI6/DO6. Alarm output relay 18

Configuration codes There is also the option of setting parameters by means of two configuration codes. This function is particularly useful and time-saving 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 two configuration codes will be displayed and the arrow down button will give the parameters of the other configurations in script. The code digits in the configuration code correspond to the script parameters below in numerical sequence. This means that the first digit 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. By going through the parameters and filling in the figures beside 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 When one or more parameters have been changed the controller will restart when the user leaves the configuration menu. CONFIGURATION-CORRIGO C40 A B C D. E F G H.

24 1. Supply air temperature control, outdoor temperature compensated. Supply air control with outdoor temperature compensation The temperature sensor Supply Air (AI6) controls the sequences to reach setpoint. The setpoint is compensated with respect to the temperature at outdoor temperature sensor (AI5). Parameters are set in the menu Temp control where menus for outdoor compensation will become accessible when this selection is made. Outdoor temperature compensation can be set with two breaking points and two end positions, see the section Temp control. Frost protection sensor Supply-air sensor 2. Room temperature control, cascade connected. Room temperature control with cascade control of the supply air temperature The temperature sensor Supply air (AI6) 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 (AI7) 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 Temp control, see the appropriate section. N.B. 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). Frost protection sensor Room sensor Supply-air sensor 25

25 Room-temperature control with min-/max limitation of supply-air temperature The room temperature sensor (AI7) controls the sequences so that the setpoint is reached. The supply-air temperature at the sensor (AI6) is kept within the set minimum and maximum limits. 3. Room temperature control with min/max limiting Frost protection sensor Room sensor Supply-air sensor Room temperature control without supply air sensor The temperature sensor Room (AI7) controls the sequences so that the setpoint is reached. 4.

When not in use Sequence Y2 1. AO2 Plate heat exchanger 1 AO2 Plateexch Means that the output controls e.g. a damper actuator for the heat exchanger bypass duct. Defrosting Ice-build up sensor is connected to DI4. On ice build-up the defrosting function is activated. -The heat exchanger is set to full bypass and the heating sequence works primarily 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 operating. If the fans are of the two-speed type they will operate at low speed while the defrosting function is active. -Defrosting will continue until the ice build-up sensor returns to normal, with a deactivation delay of 10 minutes. If defrosting still is active after 30 minutes, the supply air fan will be shut off until the defrosting is completed. 2.

A heat exchanger will be set to full capacity and dampers to maximum recirculation. The value for minimum percentage outdoor air is set under the menu Settings. 0. No 1. Yes L. FREE COOLING If the night temperature at sensor Room (AI7) exceeds a preset temperature the supply and exhaust air fans are started to give free cooling. Heating, heat exchange and cooling are not used during free cooling. When two-speed fans have been configured the fans run at high speed during free cooling. Other prerequisites are that the outside temperature exceeds the preset value (basic setting +10 C.) to prevent condensation and that the outside temperature is a preset number of degrees lower than the room temperature (factory setting 3K). If this condition is not met, no cooling run will take place. 0. No 1. Yes M. FUNCTION INPUT DI6 OCH OUTPUT DO6 These can be changed for various functions. 0. External alarm + frost protection. DI6 receives an external alarm. The alarm is presented in the alarm queue as External alarm. DO6 is controlled to be on as long as the frost protection is in the normal position. When the frost alarm is activated the output is deactivated. This function is used when external switches for manual operation of the fans is desired. 1. Auto + Frost protection In this position DI6 receives a signal that external switches are not in the auto position. It is used primarily when the relay module RM6H-24/D with external switches is connected to the controller. If any one of the switches is not in the Auto position the alarm will be given after 5 minutes. DX Cooling 0 No N.B.

Running time during a holiday is set by programming the day H into one of the three scheduler periods. If the system is to be closed down during a holiday no setting will be necessary for that holiday scheduler period. Holiday period Holiday periods. Accessible from level 2 and up. For longer holiday periods, e.g. the Christmas break, Summer holidays etc. the first and last dates of the period are set. Set the running times in the time period 1,2, or 3 above for the days that the holiday programme is to apply. If the system is to be closed down during a holiday no setting of schedule period will be necessary. 39

39 Alarm settings Here all settings for the alarm system are set including alarm parameters, delays, suppression times etc. 1. Temperature deviation alarm Should the actual temperature differ from the setpoint by more than the set value an alarm will be activated after a set time. 2. Outdoor temperature range within which the temperature deviation alarm can be activated To prevent alarms when the outdoor temperature leads to conditions beyond the system capacity. Example: If a system for supply air control does not have cooling an alarm will be given when the outside temperature exceeds 20 to 25 degrees since the temperature cannot be reduced. To avoid a false alarm the upper temperature limit is set at 20 degrees in this case. The same is true at the other extreme. If the outside temperature should fall below the set temperature a false alarm can be avoided by setting the lowest outside temperature limit to this temperature. N.B. This function is not available unless an outdoor sensor is connected to CORRIGO. 3. Pressure deviation alarm (C20 and C40 only) Should the actual pressure differ from the setpoint by more than the set value an alarm will be activated after a set time. 4. Alarm suppression Supply air fan A fan pressure deviation alarm is suppressed by a set time to avoid the alarm stopping the fan during start up before the pressure has reached the normal level. 5. Alarm suppression Exhaust air fan As for supply air fan above 6. Alarm output suppression The alarm output relay can be blocked so that unprioritised alarms will only be forwarded during the set time and not during the night or weekends, for example. Outside the set period only frost alarm, high temperature alarm and fire alarm will activate the alarm relay. Set the times in this menu when alarms are forwarded to the alarm relay output. Example: An alarm is only to activate the alarm output between and 17.00, Monday to Friday. The setting will be as follows: Temp.dev. alarm 5.0K / 2 min Outd.Temp range 20.0 C/-20.0 C Press.dev.alm 50 Pa / 2 min Alarm delay SF 30 sec Alarm delay EF 30 sec Alarm out 08:00 MTWTF -17:00 N.B. Even if the alarm output is blocked the alarm will be registered and indicated by the red flashing alarm diode and the alarm list menus will function as normal. 40

40 Stop Exch alarm No 7. Stop on alarm from rotating heat exchanger An alarm from a rotating heat exchanger can initiate a complete stop of the unit. This to prevent running at too low a temperature. Heat exchanger malfunction can also lead to unneccessarily high running costs which is avoided by stopping the unit when an alarm is indicated on input DI4. The function is only available if rotating heat exchanger has been configured.

41 Settings This menu contains various settings that are normally only set at the comissioning of the CORRIGO. Which alternatives are shown depends on the model and the configuration settings. 1. Setpoint, frost protection function. Only when water heating with frost protection has been configured.see also pages 27 and 29. Factory setting 7 C. Range C. 2. Setpoint shutdown control. Only when water heating with frost protection has been configured.see also pages 27 and 29. Factory setting 25 C. Range C. 3. Pump stop. Only when water heating has been configured. Outside temperature above which the pump is permitted to stop with no heating requirement, i.e. output heat is less than 1%. Delay time for the pump can also be set. Factory setting 6 C. and 15 minutes. Range C. and min. 4. Supply air fan run on time for cooling electric heater. Only if electric heating has been configured. Factory setting 120 sec. Range sec. 5. Supply air fan delay at normal start up. Period for which heat exchanger is to run at 100% at start up. Startup is normally done with only the exhaust-air fan running. With C20 and C40 the fan will be running at reduced flow. With C10 and C30 the fan will be running at low speed it two-speed running has been configured, otherwise at normal speed. After the set time the supply-air fan is started at reduced flow level(c20 and C40)/ low speed (C10 and C30) if two-speed running has been configured. If the fans shall run at normal speed the exhaust-air fan will now switch to normal speed and 5 seconds later also the supply-air fan. If any of the temperature control outputs has been configured as heat exchanger, this output will at startup be set to 100%, that is to maximum heat exchange, for the set time. The other outputs will be held at 0 % output until the supply-air fan is started. If a cooling demand is at hand, the cooling output will not be activated until the exchanger startup period has run out. Factory setting 60 sec. and 90 sec. Range sec. and sec. 6. Extended running. When set for DI7/DI8 using pushbutton. See page 30. Sets required running time after using push button. The function is not additive i.e. multiple pressings of the button will not give longer running time. Factory setting 0 min. Range min. 7. P-band Y2,Y3. Factor of P-band for Y1. Multiplication factor compared to the proportional band set for output Y1. Does not normally need setting. Option available for plants where control enhancement for respective devices are different. Factory setting 0.5 / 0.5. Range and Minimum fresh air percentage when using mixing dampers on Y1 or Y2. See page 30. Factory setting 0%. Range %. 9. Free cooling. Lowest outdoor temperature and differential between room and outside temperature. See page 30. Factory setting 10 C. and 3K. Range C and K. 10.Free cooling. Setpoint for room temperature. See page 30. Factory setting 21 C. Range C. 11.Cooling recovery. Differential outdoor temperature/room temperature. See page 30. Factory setting 2K. Range K. 42

42 12.DX cooling. Minimum on and off times. See page 30. Factory setting 5 min. and 5 min. Range min and min. 13.Lowered minimum limit by DX cooling. See page 30. For control configurations with minimum limiting of the supply-air temperature (control functions 2, 3, 5 and 6) the minimum limit temperature will be lowered by the set number of degrees when the cooling is activated. This is to reduce the risk of the minimum limit causing a premature stopping of the cooling. Factory setting 5 K. Range K. 14.DX cooling.minimum outdoor temperature. Control function 5 only. At outdoor temperature lower than the set value the DXcooling outputs will not be activated. Factory setting 12 K. Range C. 15.Time for fire damper exercise. Factory setting 12 midnight. Can be set at any given time during the day or night. 16.Min. temp and P-band for liquid connected exchanger Factory setting 2 C and 5K Range C and 0...5K 17.Force low speed on fans when outdoor temp. is lower than set value.
