Configuring, commissioning and maintenance made easy. Full control from anywhere.
Fast and easy start-up on site
Regin's heating controller Exigo is designed with usability and customer experience in focus. This is what makes it fast, easy, and very cost-efficient to install and configure.
For installers on-site, it is easy to download the right application directly into the controller. The simple navigation system of the display makes it quick and easy to configure all settings.
Configuration and commissioning on the fly. Application tool.
The configuration software Application tool gives system integrators easy access to the preset applications in the controller. Application tool gives access to energy-efficiency functions, such as effect-limitation, monitoring of energy consumption. It also makes it possible to create functions with wireless sensors.
CLOUDigo - your own Mini BMS. The cost efficient solution for remote heating control
CLOUDigo gives building owners one of the most flexible control systems on the market. The HTML5-based portal can function as a "Mini-BMS" with full functionality, but at a minimum cost and faster and easier installation and commissioning.
Access all values and logs in your properties from any mobile device, regardless of where you are, and start saving time. CLOUDigo detects and categorizes deviations and sends all A-alarms via e-mail to ensure immediate handling.
CLOUDigo reads the configuration of the control system and automatically creates a schematic and dynamic flow image. It provides a good overview of the system while making all setting values accessible. Through different authorization levels, you can control who gets to see and do what. Many building owners also appreciate the simple logging feature that can facilitate troubleshooting and report generation.
Prepared for cloud connection!
Regin's cloud portal for Building Management is equipped with a Graph QL (a query language for your API) gateway for smooth data sharing with other cloud-based systems.
Versatile heating systems are future-proofed through functionality
Smart metering for more efficient energy calculations
Trustworthy measurement data is key to truly energy-efficient heating systems. M-Bus metering helps you utilize all data to fine-tune your heating system.
Several models of the Regin heating controller Exigo are open for M-bus communication. Calculate your key energy figures by capturing the energy and environmental data from sources with M-bus communication, such as power consumption or gas volumes. Use this data in the web portal CLOUDigo to adjust the system or aggregate the data to your central BMS.
Peak control for maximum energy savings
One of the top challenges for energy-efficient heating systems is to avoid high power peaks when the consumption of hot water in the building is high. A smart heating system will "borrow" energy from the heating system and use it for a short time period to heat the water instead. In that way, the combined power consumption will be lower, even in cases when hot water and the heating system are used at the same time.
The Regin toolbox for efficient heating solutions. Designed for maximum performance and minimum cost
Every year, we develop and manufacture controllers and components for sustainable heating systems with usability, scalability, and overall cost-efficiency in focus. After 75 years on the market, we know that an efficient heating system is about much more than just the controller. It’s about helping building owners find possibilities for energy savings in every single part of the solution.
Configurable controllers for time-saving installation
Exigo has been developed to be your perfect companion for any challenge where the answer is efficient, intelligent heating solutions and energy savings. The Exigo heating controllers are available in models with 24 V or 230 V, prepared to handle a wide variety of applications from district heating systems to boilers, solar circuits, and buffer tanks with one or several heating circuits. The configurable heating controllers contain loads of smart time-saving features that make it possible to get started in no time. Exigo heating systems are easy and very cost-efficient to design, install, commission, and expand – all according to your specific requirements.
Expand and add functionality as requirements change
Regin heating solutions are designed for cost-optimized installations, while they provide a future-proof basis for development. The heating controllers in the Exigo family are all equipped with one, two, or three communication ports as a standard. As the requirements of a heating system change, it is easy to expand the unit with extension units that provide additional IO:s.
This means that the system can be upgraded step by step, putting you in control of the costs.
Versatile displays for your heating system
Get a full overview of your Exigo heating application with the touch screen display ED-T7. The display adapts automatically to the program inside the Exigo controller. Just connect it to the display port and start configuring your system in an easy-to-use interface.
Configuration made easy for installers
With the E3-DSP stand-alone display and configuration unit installers get access to a simple text display that can be used to change setpoints, adjust heating curves, or start and stop the system. It saves time for installers when the Exigo heating controller is prepared before installation. On-site, the unit is used as a display and is very useful in times when there is no access to Application tool via the computer.
Fine-tune the temperature curve with wireless sensors
Wireless sensors in apartments help to keep an even temperature level and increase energy efficiency. The temperature in specific zones can be controlled and logged automatically. With the transferred values, the Exigo heating system will recalculate and adjust the temperature to ensure a high level of comfort and an even temperature curve everywhere. That way, caretakers don't have to make any manual adjustments to ensure optimum energy consumption.
Regin's range of Go-Wireless sensors includes everything from room-and outdoor sensors to presence detectors with Modbus communication. With Exigo, your system can handle up to 16 wireless temperature sensors with a communication range of up to 300 meters. In other words, you have all you need for an efficient heating system.
Sensors for any requirements of your heating system
Any heating system requires a range of sensors that make it possible to fine-tune your system for optimum performance. At Regin, you find various sensors and transmitters for temperature & humidity, thermostats, and humidistats, as well as advanced wireless sensors for specific requirements.
Valves for high performance heating systems
Regin has a broad range of 2- and 3-way valves with fitting actuators in sizes from DN15 to DN200 with Kvs-values ranging from 0.25 to 550. There are various models, everything from small zone valves including pressure independent control valves (PICV´s) to flanged and large heating valves. At Regin, you also find energy-efficient valves with a 0% leakage rate for long-term savings in your heating systems.
Actuators for valves in heating applications
Regin offers a wide variety of actuators for temperature control. There are models available for most heating applications from 2-point control to control of mixing or diverting valves where intermediate positions are vital for the control of two flows.
Connect energy meters to your building management system and measure the energy consumption of any district heating system or heating system based on for instance radiators, underfloor heating, or convector heating. They are also applicable in any system for the production of domestic hot water. No matter your system composition, you can easily monitor and register any deviations to assure cost-efficiency.
