EU- i-3 PLUS Controller for controlling 3 mixing valves

EU- i-2 PLUS Controller for controlling 3 mixing valves

Control for heating systems. Operation of two mixing circuits, DHW circuit, OPENTHERM output, communication with the heat source, 2x 0-10V output, cascade controller for up to six heat sources, possibility of creating two direct heating circuits or controlling other 230V devices (lighting, irrigation, switching zone valve, etc.), possibility of interconnecting two heating sources using a voltage-free NO/COM/NC output when using an internet module, full control of all functions via the internet.

Functions performed by the control:

• Continuous control of two mixing valves and their pumps with the following options:
  • constant temperature,
  • equithermal regulation,
  • valve temperature correction according to room temperature,
  • weekly heating program
• DHW preparation with weekly program and functions Legionella. 
• Four identically configured outputs for interconnecting heat sources or operating executive elements based on temperature and time (gas boiler, electric boiler, heating coil, pumps, valves, storage tank, etc.):
  • Two voltage-free outputs (NC/COM/NO).
  • Two voltage outputs (230V).
• OPENTHERM communication with the heat source
• Two analog outputs 0-10V
• Cascade controller with the possibility of creating a cascade of six heat sources (using 2x voltage-free output, 2x voltage 230V, 2x 0-10V) based on a constant temperature, equithermal or heating need of active circuits.
• Cooperation with two room thermostats with standard communication ( two-position - on/off ) with the possibility of reducing the valve temperature or closing it.
• Cooperation with two room thermostats with RS communication dedicated to EU-i-2 PLUS OT ( EU-RI-1 ) with the possibility of dynamically changing the valve temperature or closing it.
• Cooperation with a room thermostat equipped with RS communication, which allows, in addition to setting daily and weekly changes in the room temperature, also viewing and changing the temperatures of mixed circuits, DHW, and automatic temperature correction (+ and -) of the valve based on changes in the room temperature.
• Possibility of connecting the EU – 505 Ethernet or WiFi RS module, which allows remote control of functions and monitoring of parameters via the Internet ( eModul.eu application), sending email messages in the event of an alarm.
• The possibility of connecting two additional modules for controlling mixing valves and their pumps allows you to control up to five mixing circuits (e.g.: EU-i-1m or EU-i-1 ).
• Protection against unwanted increase in hot water in the short boiler circuit and against too low a temperature of heating water when returning to the boiler.
• Possibility of updating the program via USB input.

Control equipment:

• large color LCD touch screen
• solar collector temperature sensor
• equithermal sensor (outdoor temperature)
• valve temperature sensors, boiler temperature, return temperature, DHW sensor
• cover adapted for wall installation
