CTC EcoLogic II

Smart control for all heating systems - Flexible, future-proof and easy to use.

Intelligent and flexible control of the entire heating system. A future-proof solution with genuine EnergyFlex – smart, user-friendly and expandable.

Smart control for all heating systems
CTC EcoLogic is the heart of your heating system. The intelligent control module gives you full control and maximum flexibility – whether you are building new, upgrading or combining multiple energy sources. With three powerful models, adapted for everything from single-family homes to large properties, CTC EcoLogic is a future-ready solution designed to meet all needs.

Three variants for different requirements:
CTC EcoLogic M – ideal for smaller systems, supporting up to two heat pumps.
CTC EcoLogic L – for larger installations, supporting up to ten heat pumps, with functions such as pool control and cooling.
CTC EcoLogic XL – maximum capacity with dual tank sensors and support for both active and passive cooling from ground source and air-to-water systems.
CTC EcoLogic M and L can also be upgraded if the heating system needs to expand in the future.

Flexible hybrid solutions
With CTC EcoLogic, you can combine different energy sources – for example ground source heating and air-to-water – within a single system. The control system manages both heating and cooling, active and passive, and automatically optimises energy usage. The result is a flexible, energy-efficient and comfortable system that operates all year round.

Easy connectivity and control
With built-in Modbus TCP/IP connectivity, CTC EcoLogic can be easily integrated into higher-level systems without the need for additional accessories. Through the myUplink app, both property owners and installers have full control of the installation.

CTC – Experience you can rely on
CTC is a Swedish brand with over a century of experience in heating technology. When you choose a product from CTC, you’re not just investing in reliability — you’re getting solid warranties, expert service, and support from people who know the system inside and out.
