Download PDFThe EU-i-2 PLUS OT controller is designed for the seamless control of two mixing valves and their pumps. It allows heating based on a constant or weather-compensated temperature, with the option to adjust according to room temperature. It also includes control of DHW heating with a weekly program and an Anti-legionella function. The controller can operate in cascade mode and control up to six heat sources. Communication with OpenTherm, RS thermostats, and two-position thermostats is supported.
The device features two voltage-free and two voltage outputs, two 0–10 V analogue outputs, and supports the connection of an internet module (Ethernet or WiFi). By using expansion modules (EU-i-1, EU-i-1M), it is possible to control two additional mixing valves, extending control to up to five heating circuits. It also includes a USB input for software updates, return and boiler protection, and compatibility with various types of thermostats.
