- Flexible and future-proof control for all heating systems

CTC EcoLogic is the ideal control module for simple, flexible, and future-ready heating management. Whether building a new system or upgrading an existing one, it offers precision, adaptability, and ease of use for modern, efficient and sustainable heating solutions.

Adaptable models for different systems

CTC EcoLogic comes with built-in internet connectivity and offers four variants, designed for everything from basic control to complex property systems.

• CTC EcoLogic S: Designed for one heat pump handling heating or hot water, ideal for systems with hot water tanks or older indoor modules like CTC EcoEl.
• CTC EcoLogic M: Controls up to two heat pumps (one for hot water) across two heating systems, plus peak heating. Perfect for medium-sized properties.
• CTC EcoLogic L: Manages up to ten heat pumps (two for hot water) across four heating systems, plus peak heating, DHW, pools, active cooling (air-to-water) and passive cooling (geothermal). Suited for large properties.
• CTC EcoLogic XL: Our most advanced model controls up to ten heat pumps (two for hot water) across four heating systems. It handles peak heating, dual tank sensors, DHW, pools, and both active and passive cooling. A real-time monitoring feature is also in development for easy system status updates.

Easy connection and control

With built-in Modbus TCP/IP, the system connects easily to higher-level systems without extra accessories. The myUplink Pro app gives property owners and installers full control anytime, anywhere.
