The time shown in the display is one hour
o?
See ‘Time and Date’.
The time shown in the display is not
correct?
The internal clock may have been reset, if
there has been a power break for more than
72 hours.
Go to the ‘Common controller settings’ and
‘Time & Date’to set the correct time.
The ECL Application Key is lost?
Switch the power o and on again to see the
system type and the software generation of
the controller or go to‘Common controller
settings’>’Key functions’> ‘Application’.
The system type (e.g. TYPE A266.1) and the
system diagram is displayed.
Order a replacement from your Danfoss
representative (e.g. ECL Application Key
A266).
Insert the new ECL Application Key and copy
your personal settings from the controller to
the new ECL Application Key, if required.
The room temperature is too low?
Make sure that the radiator thermostat does
not limit the room temperature.
If you still cannot obtain the desired room
temperature by adjusting the radiator
thermostats, the ow temperature is too
low. Increase the desired room temperature
(display with desired room temperature).
If this does not help, adjust the‘Heat curve’
(‘Flow temp.’).
The room temperature is too high during
saving periods?
Make sure that the min. ow temperature
limitation (‘Temp. min.’) is not too high.
How to make an extra comfort period in
the schedule?
You can set an additional comfort period
by adding new‘Start’ and ‘Stop’ times in
‘Schedule’.
How to remove a comfort period in the
schedule?
You can remove a comfort period by setting
‘Start’ and‘Stop’ times to the same value.
