EU-11 Eco Circulation

Functions performed by the controller:

• control of the circulation pump operation,
• control of the set temperature in the circulation branch,
• ntelligent control of the circulation system,
• protection against overheating (starting the domestic hot water pump),
• anti-stop function,
• adjustable pump operation time

Controller equipment:

• 2 temperature sensors
• flow sensor (from 1l/min)
• LCD display

Principles of operation

The DHW EU-11 circulation controller is designed to control the DHW circulation system in such a way as to adapt to the individual needs of each user.

It reduces the waiting time for hot water at the point of use in the most economical way, while maintaining the comfort of use. Controls the operation of the circulation pump,
which, when the water is drawn by the user, accelerates the inflow of hot water to the point of consumption, replacing the water there with hot water at the desired temperature in the circulation branch and at the point of consumption.

The control system controls the temperature set by the user in the circulation branch and only after lowering the set temperature starts the pump, and therefore does not generate heat losses in the DHW system. It saves energy, water and device operating in the system (e.g. circulation pump).

Again the circulation system will work only when the user requests hot water and the desired temperature in the circulation branch drops at the same time. Device controller
it has all the necessary functions to adapt to a variety of DHW circulation systems. It has the function of controlling the operation of the hot water circulation, in addition
it can start the circulation pump when the hot water heating device overheats (e.g. in solar systems).

The device is equipped with pump anti-stop function (protects against blocking of the pump impeller), adjustable circulation pump operation time, individually initiated by the user.
