4. Enter the service password and press on the mark's confirmation;
5. Enter inside the "Addresses configuration";
6. Enter inside the "Addresses assigns";
7. Change the address with the arrows: the addresses can be assigned from the number 10;
8. Push on the confirmation icon next to the word "Start:";
9. After a few seconds you will see "Set";
10. Remove power supply from the first fan coil and power on the second;
11. Perform the same steps 7 through 9 for each fan coil units connected to the same keyboard.
12. It is important to assign to the fan coil units that will be bound to the same zone a series of consecutive addresses (e.g.
whether there are 3 fan coil units within the same hall and if you want to associate them with a single thermal zone that we
call HALL, you must give the themselves a series of addresses from 10 to 12, etc..).
4.5.2 SCAN NETWORK
Once each fan coil has been addressed , it is essential to perform a network scan to check whether all the fan coils are correctly
recognized. To do this:
1. restore power supply to all the fan coil;
2. enter to the service menu following the same procedure described in the previous section (points 2‐4) and enter "Scan
network";
3. press the tick confirmation closer to the word "Start" and let the system scans the network;
4. after scanning the system should find all of the chiller (max. 7 in cascade) and all fan coil units connected to the same
network. If the number of fan coils found does not match those installed, the wiring was not performed properly.
If one or more fan coil properly addressed and identified, get disconnected from the network (for example, due to a failure of the
fan coil power supply), the keyboard proceed with the updating of the number of the actually working fan coils in the system with a
delay of 2 minutes from the occurrence of the event, accompanying the update with a an error message. When the fan coils are re‐
connected, the keyboard recognizes them automatically, saving the settings previously set.
4.5.3 AREAS FAN COIL ASSIGNMENT AND CUSTOMIZING THE AREA'S NAME
To match the fan coil to the desired areas you must perform the following steps:
1. enter the "Configuration" and from here going in "Service menu " following the same procedure described in Paragraph
4.5.1 (steps 2‐4) and select the "Area configuration";
2. press on "Zone 1";
3. press on the second line where it appears the current name "Zone 1" and change the zone name using the keyboard that
appears (you can enter up to 9 characters);
4. to confirm the new name, press "Enter", otherwise press on "Esc";
5. press the value that appears at the words "From" (the value is highlighted in red);
6. use the arrows to select the address of the first fan coil units in the area that you are configuring;
7. press the tick confirmation;
8. press the value that appears in correspondence of "To" (the value is highlighted in red);
9. use the arrows to select the address of the last fan coil units in the area that you are configuring;
10. press the confirmation tick;
11. repeat steps 2 through 10, using the procedure to other areas that you want to configure.
4.6 ASSOCIATES UNIT OPERATION
4.6.1 ON/OFF
Once executed the zone configuration and the association of the fan coil, you can proceed to the "first start" of the connected units.
You can turn on or off with a single tap the whole system headed by a single keyboard Hi‐T; otherwise you can individually turn on
the chiller and manage individual zones.
For operate the entire system:
1. from the main page of the system, go to "Status setup ;
2. in the menu that appears are listed: SYSTEM, CHILLER, ZONE‐nth.
3. Push on "System" and with a single operation you can turn on or off all fan coil units of all the areas connected to the
keyboard Hi‐T and all the chillers that are part of the same system:
