Heating is usually the highest item on household bills, as well as for commercial or office buildings. If you are also looking for ways to live economically and ecologically, you should not miss the opportunity for energy savings through weather-compensated control.
Digital thermostats ensure automatic regulation of the heating system based on several important factors. A weather-compensated controller is another element of automation that further increases thermal comfort indoors and reduces heating costs. How?
Simply put, a weather-compensated controller optimizes the operation of the heating system based on the current outdoor temperature. If the outdoor temperature drops, the weather-compensated controller increases the temperature of the heating water, ensuring a stable room temperature. Conversely, if it gets significantly warmer, the weather-compensated controller reduces the heating output to prevent unnecessary overheating of the interior. This, of course, reduces heating costs.
The weather-compensated controller thus communicates with the local heating source – most often with a heat exchanger or boiler. The sensors of the weather-compensated controller transmit information about the currently measured temperatures to the control unit. The software then evaluates this data based on the so-called weather-compensated curve and adjusts the boiler's output to achieve the desired heating water temperature.
A weather-compensated controller ensures a stable indoor temperature even with large fluctuations in outdoor temperature.
A weather-compensated curve is a graph that determines the interrelationship between 3 basic variables:
outdoor temperature,
heating water temperature,
room temperature (optional).
For the operation of a weather-compensated controller, it is not necessary to measure the indoor temperature, as the software can calculate this variable itself based on the input data about the building and heat losses. Before commissioning the weather-compensated controller, the user selects which weather-compensated curve they want to regulate their heating by.
The weather-compensated curve itself must then be set in the device by a specialist. The heating designer calculates the optimal weather-compensated curve based on your preferences, building parameters, and heat losses.
So what are the main advantages of weather-compensated control?
Optimal thermal comfort even with large and unexpected fluctuations in outdoor temperature,
stable indoor temperature without fluctuations,
automatic heating regulation without the need for manual intervention,
cost optimization for heating.
The only disadvantage of weather-compensated control is the need for professional installation of sensors and setting of the weather-compensated curve. It is also necessary to have a boiler and heating system that allow this type of regulation.
Weather-compensated controllers are very versatile devices and can be used in family homes as well as larger public and commercial buildings or apartment buildings. These devices can regulate heating and hot water heating and can communicate with all types of local heating. They are suitable for radiators and underfloor heating, all types of boilers, solar heating, heat pumps, or heat exchangers. Weather-compensated control can even be used in remotely heated apartment buildings, but in this case, the cooperation of all unit owners is necessary. Particularly high savings can be achieved with gas condensing boilers.
As we have already mentioned, when choosing a specific model, do not forget to check compatibility with your boiler and heating system, i.e., your boiler must support this type of heating system control and have the appropriate software.

First of all, when choosing, consider the purpose of the controller, i.e., whether it is intended for local or remote heating and also whether you want to use it for regulating hot water heating. Also, make sure that the model you choose is compatible with your heat source and heating system.
Each weather-compensated controller has a different range of measured temperatures, so when choosing, also consider the lowest measured outdoor temperature in the given location. Some weather-compensated controllers have the option of remote control via the internet. So if, for example, the outdoor temperature drops significantly, but you are not at home, you can easily change the heating settings via the internet so that it does not unnecessarily increase its output. Models with a touch display will provide you with clear information about the measured temperatures and heating output and also allow you to easily control the controller.
A weather-compensated controller requires a set of temperature sensors for its operation, primarily outdoor ones, optionally also room sensors, which are placed indoors. For the design of the optimal set, we recommend consulting with experts who will also recommend the most suitable placement of weather-compensated sensors and set the weather-compensated curve for a specific building or room. We definitely do not recommend self-installation.
In our offer, you will find weather-compensated controllers for home use as well as complex devices for exchange stations, including all necessary accessories for temperature sensing and installation.
