7.4 Frequently asked questions
The definitions apply to the ECL Comfort 210 / 296 / 310 series.
Consequently, you might come across expressions that are not
mentioned in your guide.
Circulation pump (heating) does not stop as expected
It is in operation at frost protection (outdoor temperature
lower than "P frost T" value) and at heat demand (desired flow
temperature higher than "P heat T" value)
The time shown in the display is one hour off?
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 off and on again to see the ECL controller
type, version code (e.g. 1.52), code no. and application (e.g.
A266.1) 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 flow 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. flow temperature limitation ('Temp. min.')
is not too high.
The temperature is unstable?
Check that the flow temperature sensor is correctly connected
and in the right place. Adjust the control parameters ('Control
par.').
If the controller has a room temperature signal, see 'Room limit'.
The controller does not operate and the control valve is
closed?
Check that the flow temperature sensor is measuring the correct
value, see 'Daily use' or 'Input overview'.
Check the influence from other measured temperatures.
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.
How to restore your personal settings?
Please read the chapter concerning ‘Inserting the ECL Application
Key’.
