The icons will be highlighted in green if that
part of the system is on and white if it is off.
Some of the symbols displayed on this screen
will depend on the set up of your heating
system, therefore some icons may not be
visible. In this screen, you can also access an
additional menu which allows you to change the
date and time, the outside off temperature and
to view a list of any messages that occur. This
menu is accessed by turning the rotary dial to
the ‘Login’ button and middle clicking. Turn the
dial to ‘998’ and middle click again.
4.5.1 Adjusting the date and time
The date and time will be set during installation.
If for any reason you need to adjust these
settings you can do so by using the ‘Login’
button in the information screen, as shown in
figure 17. Turn the rotary dial to the login
button and middle click. Turn the dial to ‘998’
and middle click again.
4.5.2 Information – Message list
If the information symbol on the home screen is
highlighted orange, it means a minor fault has
occurred. When the message icon is highlighted
in red on the home screen, it usually means
there is an issue with the operation of the heat
pump. When you see this you must contact the
heat pump installer and provide them with the
error code.
The full message list can be viewed by entering
998, similar to the date and time menu
described in section 4.5.1. If a message is
active, it will be highlighted orange. Selecting
the message (by middle clicking the rotary dial)
will open a list of details about the system
operation the moment the message occurred.
4.5.3 Changing outside off temperature
You may not require your heat pump to come
on in warmer months, when the outside air
temperature reaches a certain level. You can
change the outside off temperature in the
information menu, by entering ‘Login = 998’ as
before. In this menu you will see a submenu
called ‘General DHW & Heating Control’.
Accessing this menu will allow you to change
the outside off temperature, by clicking on the
temperature and turning the dial to increase or
decrease the temperature.
If the outside off temperature is set too low for
your environment (e.g. default outside off
temperature is 18°C) and the temperature
outside surpasses this (e.g. it is 20°C outside
during summer), the heating will be switched
off and will revert back to the set back
temperature (see section 4.3.3) until the next
change. This can be prevented by increasing
the outside off temperature.
You will also find a number of other sub menus
in the ‘Login = 998’ menu. These menus display
information about temperatures in each zone,
which may be required when speaking to a
service agent.
