Before you start
Save energy - save money - improve your
comfort temperature
The ECL Comfort controller is designed by Danfoss for the
automatic temperature control of heating sys tems.
The advantages of the ECL Comfort controller system are
the security of your heating control and the op ti mum use
of energy resources.
Seasonal changes and variations in outdoor temperatures
are mon i tored by the control system.
Decreased temperatures and low energy consumption
while you are out or asleep save heating costs.
The temperature programming provides comfort and
the au to mat ic pump motion program protects against
blocking.
Time control of the ECL Comfort 100M controller
When an analog clock is mounted the controller can
reduce or increase the room temperature automatically.
This ensures comfortable temperatures when you are at
home and helps you save energy and thus reduce costs
while you are out.

Clock (optional)
A clock can be mounted when an automatic change between
comfort temperature and reduced temperature is desired.
Setting the clock
Turn the minute hand to set the actual week day (7-day clock)
and time.
Note!
You will move the entire outer ring of the clock with its sliders,
just by turn ing the minute hand. Turn the minute hand until
the white ar row points at the actual week day and hour in the
outer ring.
Note!
Do not turn anti-clockwise, as this may damage the clock.
Summer time setting
Remember to set summer- and wintertime +/- 1 hour.
Individual comfort and reduced
tem per a ture periods
Determine in which periods of time you want comfort
temperature or reduced temperature. Look at the week
days and hours written in the outer ring of the clock. You
can choose heating at comfort temperature by set ting the
slid ers in the outer ring to point towards the cen ter. If you set
the slid ers to point outwards, you set the heat ing sys tem to
re duce temperature at the cor re spond ing pe ri od of time.

Adjustments
• With room sensor.
If the wanted comfort temperature is not reached?
Make sure that the radiator thermostat/valve is fully open in the
room with the room sensor.
• Without room sensor.
The rooms seem to be too cold?
Before adjusting the comfort temperature on the controller it
is advisable to check and perhaps adjust the settings of your
radiator thermostats/valves.
If you are not able to obtain the desired temperature by these
adjustments, the fl ow temperature is too low. Increase the
value.
See also page 12: Setting the heat curve.
Temperature setting without room sensor
(parallel displacement of the heat curve)
If you have no room sensor installed, your system will not
know the exact room temperature. Therefore you can only
use the temperature setting button to change the fl ow
temperature. This cor re sponds approx. to a possible change
in room temperature of +/- 8 °C.
Temperature setting with room sensor
If you have a room sensor installed, the midpoint of the
temperature setting button will correspond to a room
temperature of 20 °C. The room temperature can be set in a
range from 12 to 28 °C.
