Detailed description

Area of ​​application & Target audience

The TECH EU-i-1 mixing valve controller was designed for modern heating systems where precise control of the flow or return temperature is required. It is suitable for central heating systems, underfloor heating systems, and systems with backflow protection, and is primarily used in new construction and renovation projects.

Everyday benefits

The controller ensures stable temperatures and increases comfort in the building by continuously regulating the mixing valve. At the same time, it reliably protects the heat generator from excessively low return temperatures and overheating.

Technology & equipment

The controller supports three- and four-way mixing valves, including the valve pump. Up to two additional valves can be integrated via optional add-on modules. Multiple temperature sensors (boiler, valve, return, outdoor) enable precise control in various operating modes.

Efficiency & Environment

Thanks to weather-compensated control and weekly programs, the TECH EU-i-1 adjusts its heating output according to demand. This reduces unnecessary energy consumption and supports efficient, material-friendly system operation.

compatibility & System integration

The controller is compatible with TECH room thermostats (RS communication or two-point), optional internet and GSM modules, and other TECH valve modules. Integration into existing heating systems is flexible.
