3.1 Function overview
The selected control modes and activated functions depends on the selected configuration. Find more information about the available configurations in the document Optigo Ardo 1.0 - Predefined configurations, which is available on Regin's homepage www.regincontrols.com
. A description about the activation of a configuration will be found in chapter
4.1 Predefined configurations in Optigo Ardo .
The program for an air handling unit contains, apart from other things, the following functions:
Different temperature control modes
✓ Supply air temperature control
✓ Room temperature control (cascade control)
✓ Extract air control (cascade control)
With control of:
✓ Heat exchangers (plate)
✓ Mixing dampers
✓ Heating coil (water with or without frost protection, electric with high temperature limit switch)
✓ Cooling (water)
✓ Circulation pumps
Fan control
✓ 1- or 2-speed supply air and extract air fans
✓ Manual control of fans
Timer control
For starting and stopping the unit, annual clock function. One output for control of external functions such as lighting, door locks etc.
Demand controlled ventilation
In buildings with strongly varying occupancy, the fan speeds or mixing dampers can be controlled by the air quality measured by a CO
2 sensor.
Support control
When using the control function room control or extract air temperature control, it is possible to utilise support-heating and/or support-cooling.
Free cooling
When this function has been activated, it is used during the summer to cool the building during the night using cool outdoor air, thereby reducing the need to run chillers during the day.
Free heating
If the outdoor temperature is higher than the indoor temperature and there is a heating demand, the recovery damper will not open for recovery but instead open fully for outdoor air. This may occur during low night-time outdoor temperatures, when the room has been cooled considerably and the outside heat is rising faster than indoors. This function is activated at the same time as Free cooling .
Cooling recovery
If the cooling recovery has been configured, there is a cooling requirement and the extract air or room temperature is a settable amount lower than the outdoor temperature, thus cooling recovery can be

Information for the specialist
activated. When cooling recovery is activated the heat exchanger and damper sequence output signal will be activated in the cooling demand. The function also activates the heating function Free heating : if heating is required and the outdoor temperature is higher than the extract air or room temperature, outdoor air will primarily be used.
Change-over
In 2-pipe systems where a combination heater/cooler is operating together with a heat pump, change-over is a function that enables using the same pipe for both heating and cooling, depending on which is currently required.

The supply air temperature controller is reverse acting, i e. the output will increase for decreasing temperature. The temperature at the supply air sensor will be constantly kept at the user setpoint value. The controller is a PID-controller with settable P-band, I-time and D-time.
In the Room cascade and Extract air cascade modes the supply air is controlled as part of a cascade controller together with the room/extract temperature controller. The room/extract temperature offset will dictate the supply air temperature setpoint.

3.3 Temperature sequences
The supply air controller output is either a heating demand or a cooling demand depending on if the supply temperature is over or under the setpoint. This demand is then divided into up to 4 sequences A to D. Each sequence is configured as Heating , Cooling , Exchanger , Damper , or Not used depending on the selected configuration.
Each sequence has it own PID-settings that can be set in the Ventilation menu in the display.
Each of these output sequences can be bound to either an analog output, to one pulse-width modulated
(PWM) digital output with a settable period time, or to a start/stop digital output.

Freeze protection
The heater return water temperature is measured using the analog input Freeze protection temperature . Low temperatures will generate an internal, proportional signal that is used to force the heating valve open, thereby preventing freeze-up of the heater.
The internal signal will begin to rise as the frost protection temperature falls below the Alarm limitation running mode + P-band running mode in order to reach 100 % output when the signal has fallen to Alarm level .
When the internal signal reaches 100 %, the unit is shut down, the heating output is set to completely open mode and an alarm is activated. .

3.4 Fan control
3.4.1
Fan levels
Frequency controlled fans, EC-fans or fans with 2-step control work with the Optigo Ardo . The fan can be set to Low, Normal or High speed. The selection of the fan speed defines which time channel will be active in the application.
The fans will always start directly with the desired speed.
The extract air fan and the supply air fan have individual start and stop delays which are normally set so that the extract air fan is started before the supply air fan. If there are not enough digital outputs for individual control, both fans will have to be started using the signal for the supply air fan, and the delay will be created using an external time relay.
3.5 CO
2
control
In applications with varying occupancy the fan speeds or mixing dampers can be controlled by the air quality as measured by a CO
2 sensor.
With the CO
2 function it’s possible to start and stop the fans, compensate the fan speed and in combination with mixing damper let in more outdoor air depending on the CO
2 value. This can be configured with the
CO
2 control settings.

If demand controlled ventilation is activated in combination with mixing dampers, and the
CO
2
-value rises above the setpoint value the dampers controlled by a sequence with CO
2 function will be overtaken by the CO

3.6 Free cooling
This function is used during the summer to cool the building night-time using cool outdoor air, thereby reducing the need for cooling during the day and saving energy.
Free cooling requires an outdoor sensor and either a room sensor or an extract air sensor.
Free cooling is only activated when all the start conditions below are fulfilled.
✓ It is between 00:00 and 07:00 in the day (settable).
✓ The timer outputs for Normal speed, Extended running, Normal and External switch are Off .
✓ A timer channel will be On sometime during the next 24 hours.
If an extract air sensor is selected and ALL the start conditions are fulfilled, free cooling is activated and will run for 3 minutes (settable) to ensure that the temperature measurement when using an extract air sensor reflects the corresponding room temperature.
If a room sensor is selected, the unit will not start free cooling as long as all the temperatures are not within the start and stop temperature intervals.

3.7 Support control
Support control is normally used when room temperature control or extract air control has been configured.
When extract air control is configured a room sensor must be installed.
Support control can also be configured to start only with the supply air fan. In this mode, the extract air fan is not active. This requires a digital output to be configured, which controls the recirculation damper to open completely so the supply air fan can circulate the air to and from the room.
3.8 Fire
It is possible to configure the controller operating mode when there is a fire alarm. The following options are available: Stopped , Continuous run , Run via normal start/stop conditions , Only extract air fan , Only supply air fan .
It is possible to configure which speed the fan should have when in fire mode.
It’s also possible to configure if outdoor air damper and exhaust air damper should have Normal function or be Always open or Always closed . Normal function means that the damper open and close depending on if the corresponding fan is running or not.
3.9 Filter monitoring
Turn on filter monitoring to monitor the flow through the filter. Digital inputs can be used to connect a pressure switch to monitor the status of the filter and create an alarm if the signal of the pressure switch turns on.
3.10 Dampers
The outdoor air and exhaust air ducts close-off dampers can be controlled by a digital output or be hardwired to the supply air fan relays for normal, reduced and high speed in such a fashion that the damper is open when the supply air fan is running.
3.11 Changing the battery
The controller has an internal battery to ensure the operation of the memory and real-time clock in the event of a power failure. When the alarm Internal Battery is activated and the battery LED lights up red, the battery has become too weak and needs to be changed. Nonetheless, due to a backup capacitor, the controller will function at least 10 minutes without power supply.

Time/Date
Optigo Ardo has a year-based clock function. This means that a week-schedule with holiday periods for a full year can be set. The clock has an automatic summertime/wintertime change-over.
It has individual schedules for each weekday plus a separate holiday setting. Up to 24 individual holiday periods can be configured. A holiday period can be anything from one day up to 365 days. Holiday schedules take precedence over other schedules.
This menu displays time, date and weekday, and it permits the setting of time and date.
Time is shown in 24 hour format.
Date is shown in the format YY:MM:DD.
Each day has up to four individual running periods. For fans there are daily individual schedules for low speed, normal speed and high speed, each with up to four running periods.
One digital output can be used as a timer controlled output with individual week-schedules and four activation periods per day. This output can be used to control lighting, door locks etc.
In the time schedules, four periods are available for each day of the week. Also, four periods are available for days that are configured as holidays in the holiday schedule. During the periods the assigned circuit is working with the corresponding setpoint. Outside of a period the system is off.

✓ For 24 hour running, set a period to 00:00 - 24:00.
✓ To inactivate a period, set the time to 00:00 - 00:00. If all periods of a day are set to 00:00 - 00:00, the unit will not run that day.
✓ If you want to run the unit from one day to another, e.g. from Monday 22:00 to Tuesday 09:00, the desired running time for both must be entered.

Alarm configuration
The alarm configuration menu permits configuration of the priority for all alarms. A complete alarm list with default settings and actions, can be found in
. It contains all the default alarm texts and priorities.
Priority
Alarms can be given different priority levels A-alarm , B-alarm and C-alarm or Not active . The A- and Balarms are connected to the digital output sum alarm . The digital output can be inverted, so that an inoperative alarm gives a high output and vice versa. A- and B- alarms must be acknowledged to reset. Calarms automatically reset as soon as there is no longer a cause for alarm.
Stop function
Each alarm offers the possibility to choose whether an activated alarm should stop the controller or not
( Extra stop function ). The controller can also be set to run at reduced speed during alarms. Automatic restart will take place when the alarm has been acknowledged.
For some alarm types such as Electric heating overheated and Warning freeze protection it would be dangerous to not stop the unit on alarm. Therefore, for such alarm types, the program will always reset the stop function to Active even if the operator should choose Inactive .
Unfortunately it is not possible to remove the display text concerning the stop function for these alarm types. This is because the available program space demands that all alarms are treated in the same way in the display.

4.8.2
Sum alarm
There is one sum alarm function with one digital output.
✓ A and B alarms all activate the sum alarm output, if it has been configured.
✓ Class C alarms are removed from the alarm list when the alarm input resets even if the alarm has not been acknowledged.

Inputs and outputs
There is a list of input and outputs in
Appendix C Input and output lists
that can be used to help you keep track of which inputs and outputs you need to configure.
Analog inputs
Analog inputs must refer to an Agnd terminal.
Analog inputs can, depending on the configuration, be used for either PT1000 / Ni1000 temperature sensors or for 0…10 V DC analog input signals, for example from a pressure transmitter.
Digital inputs
Digital inputs must refer to +C on terminal 4. Digital inputs may only be wired to voltage-free contacts. Any external voltage applied to a digital input may harm the unit.
Universal inputs
A universal input can be configured to act as either an analog input or as a digital input.
A universal input configured as an analog input can, depending on the configuration, be used for either
PT1000 / Ni1000 temperature sensors or for 0…10 V DC analog input signals, for example from a pressure transmitter.
64 (76) Optigo Ardo manual, Rev. A
Universal inputs configured as an analog input must refer to an Agnd terminal.
A universal input configured as a digital input must, just like other digital inputs refer to C+ on terminal 4. It may only be wired to voltage-free contacts.
Analog outputs
Analog outputs must refer to a Agnd terminal.
All analog outputs can be individually set to any one of the following output signals:
✓ 0…10 V DC
✓ 2…10 V DC
✓ 10…0 V DC
✓ 10…2 V DC the same transformer pole is used as reference for all the equipment. The equipment may otherwise not function as intended and may also suffer damages.
Digital outputs
Digital outputs should normally refer to G
DO on terminal 10.
G
DO is internally connected to G on terminal 1 and supplies 24 V AC or DC depending on the choice of supply voltage.
All the digital outputs are controlled by MOSFET transistors. The outputs are internally connected with G
0 and can deliver max 2 A per output. However, the total power for all the DOs must not exceed 8 A.
A number of different wiring alternatives are possible depending on the type of supply voltage to the controller and the relay type.

5.2 Commissioning
To commission the controller, start by selecting a configuration suitable for your application.
Some of the parameters in the configuration can be changed, for example temperature setpoints. Change the setpoints if needed.
5.3 Resetting the controller
Reset the controller by pressing the reset button, using for example a paper clip.
