Installer Menu

The installer menu consists of several items that can be adjusted. To access the installer menu, press and hold the ENTER/MENU key for 5 seconds. Using the UP and DOWN, and LEFT and RIGHT arrow keys, enter 925, then press ENTER/MENU. Scroll through the list of adjustable items by pressing the LEFT or RIGHT arrow keys. Once the desired item is dis- played, press the ENTER/MENU key to select it. The screen will begin to flash. Press the DOWN arrow key to decrease the values, and the UP arrow key to increase them. To store the changes, press the ENTER/MENU key. The display returns to normal mode after one minute. Pressing the ESC/RESET key before storing changes will restore the original value. The central heating demand is detected when the room thermostat closes. When an outside sensor is also connected, the supply temperature will depend on the factory default central heating curve which is suffi- cient for most applications.

To set your own custom heat curve you will have to set the following parameters. Use the graphs in Figs. 33 and 34 to assist you in the design of the curve.

1.Minimum outside design temperature: Function 8

2.Design Supply water temperature at the minimum design outside temperature: Function 9

3.Maximum outside design temperature: Function 10

4.Design Supply Water Temperature at the maxi- mum outside temperature: Function 11

NOTE: It is important to note that the user can adjust the heat curve down by adjusting the central heating temperature to a lower setting.
