Chapter 2 Introduction to Optigo Optigo controllers Optigo is a new series pre-programmed, configurable controllers that can be set to handle everything from temperature control or humidity control to CO2 control or pressure control. OP5 and OP10 The Optigo series comprises two different types, OP5 and OP10.
Optigo OP10 Optigo OP10 is a new pre-programmed, configurable controller. It has been designed with the main intention of replacing a number of Regin’s Aqualine controllers. All configuration and normal handling is done using the display and the knob on the front.

Chapter 4 Installation and wiring Installation Optigo is intended to be installed and handled by professional personnel. The installation should conform to the requirements of installation category 3 and pollution degree 2.
Wiring This section only describes general rules and technical limitations concerning the wiring. In chapter 5 there are specific wiring diagrams for the different control modes. Choose the one suitable for the application on hand. It is important to make sure that the wiring is correctly done, in accordance with the instructions given in this manual and in accordance with local legislation for this type of installation. Supply voltage OP10-230: 230 V AC +10%, -15%, 50/60 Hz.
Analogue inputs AI The analogue inputs must refer to an AGND terminal. The analogue inputs are for PT1000 temperature sensors only. AI1 has a range of 0…+84°C. AI2 has a range of -30…+54°C Digital inputs DI The digital inputs must refer to DI+ on terminal 41. The digital inputs may only be wired to voltage-free contacts. Any external voltage applied to a digital input may seriously damage the unit.
For more power an external transformer must be used. Wire the transformer according to the following figure. The two 500 mA fuses are important to prevent possible overloading of the triacs.
Chapter 5 Control modes Optigo can be configured to any one of the following control modes. 1. Supply air temperature control. The supply air temperature is kept at the setpoint value by controlling the output signals on AO1 and AO2. A single PI control loop is used. 2. Supply air temperature control with outdoor compensation. The supply air temperature is kept at the setpoint value by controlling the output signals on AO1 and AO2. A single PI control loop is used.
For control mode 2, “Supply air temperature control with outdoor compensation” you need two sensors, “Supply air sensor” on AI1 and “Outdoor sensor” on AI2. For control mode 3, “Cascade connected room / extract air temperature control” you also need 2 sensors, “Supply air sensor” on AI1 and either “Room sensor” or “Extract sensor” on AI2. The analogue outputs can be configured to the following combinations: AO1 / AO2 1. Heating / - 2. Cooling / - 3. Heating / Cooling 4. Heating / Heating 5.
3-Position control Instead of an analogue output you can configure a single 3-position (increase / decrease) output. You will then only have the following output choices: Heating Cooling DO1 is used for increase signal and DO2 for decrease. This option cannot be combined with alarm output. A single P control loop is used. Universal input UI1 Electric heating If the Optigo is used to control electric heating UI1 is used for the high temperature limit switch. Connect and configure as a digital input.
The frost protection signal (“Internal signal”) will increase linearly to 100 % at 7°C at which point the frost protection alarm is triggered. The fan will then be shut down and the controller will go into shutdown mode. Shutdown mode (Only if frost protection sensor has been configured) Whenever the running mode switches to ”Off”, (normal shut-down or frost protection is activated) the controller will go into ”Shutdown mode”.
Wiring examples See also chapter 4 Installation and wiring. A. OP10 with electric heating (for example via PULSER-X/D or TTC25X) and damper. Cascade control B. OP10-230 with water heating, 3-position output.
Control mode 4, Radiator circuit control with outdoor curve GT2 GT1 For this control mode you need two sensors, GT1 “Supply temperature” on AI1 and GT2 “Outdoor sensor” on AI2. You can also have a room temperature sensor on UI1 to let the room temperature offset give correction to the supply temperature. Wire UI1 as an analogue input. 3-Position control Instead of the analogue output you can configure a 3-position (increase / decrease) output using DO1 and DO2.
DO3, Pump control The pump control output is activated when the temperature control output signal is greater than zero, or the outdoor temperature is below 15°C. It is deactivated when the output signal is zero and the outdoor temperature is greater than 15°C. There is a 10 minute stop delay. There is a pump exercise function which will start the pump at 15:00 (3 pm) every day and let it run for 5 minutes. The function can be deactivated. Wiring example See also chapter 4 Installation and wiring.

Chapter 6 Display and encoder All setting and configuration is done using the display and encoder. The menu information on the display is organised in a tree fashion. Using the encoder you can move between menus, set values etc. In any of the configuration menus, a click on the encoder will activate change mode. You can then rotate the encoder button to move between choices or set values. A second click of the button will accept the choice.
Setpoint When in the Base Display, a click on the encoder button gives direct access to the Setpoint menu. See chapter 7 Setpoint. If there are any active alarms, clicking on the encoder button will instead give access to the alarm handling menus. Here the alarms are displayed and can be acknowledged. There is one menu display for each alarm with symbols showing which type of alarm it is. See chapter 8 Alarm handling.
Chapter 7 Setpoint The setpoint menu is normally accessed from the Base Display by a clicking on the encoder knob. If you wish to change the displayed value, click on the knob again and the change indicators will start to flash to show that you are now in change mode. Twist the knob, clockwise to increase the value, anti-clockwise to decrease. When the desired value is shown, click on the knob to acknowledge. To return to the Base display, twist the knob.
Chapter 8 Alarm handling If there are any active, unacknowledged alarms, the alarm indicator in the Base Display will light up and start flashing. If DO1 is configured as alarm output, it will be activated. The alarm handling menus are accessed from the Base Display by a click on the encoder knob. The first alarm is displayed. There are four different alarm types: AL1 Frost protection alarm. The frost protection temperature has fallen below +7°C AL2 High temperature limit switch activated.
Chapter 9 Clock and scheduler The menus for setting the clock and the scheduler times lie in the 3-seconds level. This level is accessed from the basic level by clicking and holding the encoder knob for 3 seconds. Real time clock This sample display shows that the time is 13:48 on a Friday, the fifth day of the week. The 0.0 in the top right corner is a menu display counter. Each configuration menu has a unique number combination. All menus connected to the clock and scheduler belong to the group 0.
For example, you wish the unit to run Monday to Friday between 07:30 and 18:00, Saturday 8:00 to 14:00. Set first on-time to day 8 and 7:30, the first off-time to day 8 and 18:00. Set the second ontime to day 6 and 8:00 and the second off-time to day 6 and 14:00. Set all others to day --. If you want the unit to run around the clock, set the on-time to 0:00 and the off-time to 0:00. Menu 0.9, Override After the eight switching point menus there is a ninth, 0.9.
Should you want the comfort period on Friday to run on until 23:30 you can set the fourth on-time to day 5 and 23:30 and the fourth off-time to day 5 and 21:01. The 1 minute dip will not be noticable. Menu 0.9, Setback After the eight switching point menus there is a ninth, 0.9. In this menu you set the number of degrees you wish to lower the room temperature setpoint during the economy periods. If no room sensor is connected the supply water setpoint will be lowered by 3 times the set value.
Chapter 10 Configuration All the configuration menus lie in the 10-seconds level. This level is accessed from the Base Display by clicking and holding the encoder knob for 10 seconds. There are numerous configuration menus covering all available options and combinations. In some cases, making a certain choice in one menu will mean that you will only see certain other menus. For example, the menu for setting the damper minimum limit is only shown if you have configured AO2 to be a damper control output.
AO1 1. Heating 2. Cooling 3. Heating 4. Heating 5. Cooling 6. Heating 7. Cooling / AO2 / / / / / / / Cooling Heating Cooling Damper Damper Output symbol \ / \/ \\ // \/ \/ Graphic symbol In alternative 4, Heating-Heating AO2 will be activated first on increasing heat demand. In alternative 5, Cooling-Cooling AO2 will be activated first on increasing cooling cemand. In alternative 6, Heating-Damper, at temperatures higher than the setpoint the damper on AO2 will be fully open.
Menus X.4 P-band Here you set the P-band (Proportional band). The P-band is the control offset necessary to drive an output signal from 0 to 100%. In configurations involving two outputs the same Pband applies to both outputs. In controlmode 3, Cascade control this setting will set the P-band for the supply air controller. The P-band for the room controller is set by the cascade factor, see menu X.6 below. Menus X.5 I-time Here you set the Integration time (Reset time). Menu X.
0°C temperature boost In control mode 4 an extra temperature boost can be added at 0°C outdoor temperature. The boost recedes from the set value to 0 over ±3 degrees. Supply temp SPH SPL -20 0 +20 Outdoor temp D-factor Control mode 5, Domestic hot water temperature control is often a very difficult application which calls for responsive control. Optigo therefore utilises PID-control for this control mode. In this menu you set the D-factor. Menus X.
High temp limit switch Not used Pump exercise If the pump stands still for prolonged periods during the summer there is the risk of the pump impeller seizing. To reduce this risk the Optigo has a pump exercise function which will start and run the pump for 5 minutes at 15:00 each day. In this menu the exercise function can be turned Off if not desired. Default is On. Periodic overheating To reduce the risk of Legionella bacteria growth a periodic overheating of the water can be configured.
Menus X.9 Maximum compensation, CMP (Control mode 2) Supply air max limit (Control mode 3) High temperature setpoint (Control mode 4) For control mode 2. The maximum setpoint compensation value. Compensation will start to be added to the setpoint value when the outdoor temperature falls below the start point S.P entered in menu 2.8.
On exit from the configuration level you will not be returned to the Basic level but to the Time and Scheduler level. There is also a time-out function that will automatically exit the configuration level after 5 minutes of inaction. Storage of settings All configuration settings become valid as soon as they are entered by clicking the encoder knob. They are however not written to the flash memory until you exit the configuration level either via the OK menu or via the time-out function.
