ACCESSING AND CHANGING PARAMETERS (USER-LEVEL))

The equipment must be powered and the system return water temperature or the “OFF” indication must appear on the display.

To access and, if necessary, change the parameters, do the following::

Access to the various parameter menus.

– - Pressing the SET

key, the “Ai” indication appears on the display, indicating the temperature and pressure

parameters. Scrolling with the

and keys, the other parameter menus can be accessed: A0 (output

state), CL (clock and date parameters), SP (variable set point parameters), Sr (real non-variable display-only set

points).

Heat and Cool set point change.

To change the inlet (system return) water temperature, do the following.

– Pressing the SET key

. the first “Ai” menu is displayed; with the key enter the SP menu and press the SET key . At

this point, the “COOL” indication appears on the display, showing the Summer set point. To change the Summer set point, press the

key, and increase/decrease the previously set value with the and keys. To confirm press the key. Then press the

key to exit.

water temperature once again.

Changing the temperature differential in heating and cooling modes.

Modifica dei differenziali di temperatura in heat e cool.

To change the temperature differential of the two cycles, proceed as follows:

- Press the

and keys simultaneously. The “PAR.” indication appears on the display.

- Now press the

key to access the CF menu.

- Press the

key to access the tr menu, then press to access tr10, which indicates the temperature differential for the Summer

cycle. Press

again to access the parameter, and change the differential value with the arrow keys. To confirm press the .

Key. Then press

key to exit

- .

- To change the temperature differential of the Winter cycle, move to the tr10 parameter (see previous item).

- Press the

key until the tr10 parameter is displayed; with the key move to the tr11 parameter. Now press the key to

access the parameter, and change the differential value with the arrow keys.

- Press the

key, until the return water temperature value appears on the display.

Exit and save
