Field Settings
The field settings are used in order to set/alter the way the unit will operate,
each system/setup will have different field settings. There are different groups
of settings and they are;
20’s - There are for the weather compensation and temperature controls in
heating
30’s - These are for the cylinder
40’s - Are for backup boilers and hybrid systems
An example would be if the field setting 3011 was changed from 0 to 1, this
would tell the system there is a cylinder in the system and DHW heating will
need to be performed.
To enter field settings, press the down and set for 6 seconds, using two hands
to do this may make it easier. If done correctly, number 10 should appear on
the screen.
1.
After entering the field setting menu, press up once, 20 will show, press right and 2011 will show.
2.
To alter this, press right once, a value will appear on the left hand side of the screen. To adjust the value, press the up and down buttons, to
save press set.
3.
To go back to 2011, press left. Then we need to go to the next required setting and repeat.
4.
Once the settings in the 20’s have been set, press left twice so that 20 shows, pressing the up button will take you to 30, repeat the above
process to alter the required settings.
Once finished, press the ESC button to go back to the main menu.
