In all the presented configurations, if a Remote Control or a room unit is used, set them to room unit 1 in order to manage the
DHW functions and the boiler stand- by, as well heating zone 1. If they are set as room unit 2 or room unit 3 only heating zones
2 and 3 respectively can be managed. See the instructions manual of the respective accessories for the configuration procedure.
After each system configuration process, carry out the following procedure for saving the components to the boiler.
• Access menu 2 as indicated at the beginning of this section.
• B Configuration
• B Yes then B to confirm.

6. MIXED HEATING SYSTEM

The AGU 2.550 accessory can be configured to manage a low temperature circuit. The AGU 2.550 can therefore control the
pump, the mixing valve and the flow sensor of the selected heating circuit as shown in the following schemes.
The diagrams in this document are purely indicative and must be backed by a technical thermal analysis.
Edit the parameter governing the closing of the mixing valves, depending on the model used, according to the following
instructions.
The diagrams shown below refer to boilers with power less than 35 kW. For boilers with power over 35 kW, there must be a
hydraulic separator upstream from the boiler and the zones must be equipped with zone pumps to replace the electrovalve.
