Boiler measurements


ECO-REL module includes 6 power relays. In our case, it can control two pumps and two valves.

ECO-NAI module has 6 analog inputs for measuring flow and return boiler water temperatures as well as outdoor temperature.

Similarly, 12 digital I/O can be used. An entry is used for the "Man/Aut" command of the 3-way valve. You can place as many inputs as there are 3-way valves.

The ECO-NAI and ECO-REL modules are fixed on a standard DIN rail or a wall box.

This type of installation can be repeated to extend management to several circuits.
