4.3 Heating/Cooling
This is used to set the desired room temperature.
Use the plus and minus buttons to set the desired
temperature (setpoint), which is shown in brackets. The
actual value is shown in front of the brackets.
If heating circuit 3 and/or 4 is installed*, the symbol for
room temperature is displayed along with "3-/4" at the
bottom right of the menu.
If you want to program a temperature reduction, you
can continue to the "Night reduction" or "Holiday"
submenus. Refer to the "Night temperature reduction"
chapter.
You can select "Room sensor: No" in the "Installer/
Defi ne/Heating Circuit" menu. This can be done for
each heating circuit if it is diffi cult to fi nd a position for
the room sensor, if the fl oor heating circuit has separate
room sensors, or if you use a fi replace or open stove.
The alarm LED on the room sensor still functions as
normal.
If you use the fi re or open stove only occasionally, the
fi ring process can affect the room sensor and reduce
the temperature supplied to the radiators. It can then
get cold in other parts of the house. The room sensor
can temporarily be deselected during the fi ring process.
EcoLogic provides heating to the radiators using the
set heating curve. The radiator thermostats reduce the
heating supplied to the section of the house where a fi re
is burning.
When holiday reduction is activated, H appears after the
brackets, e.g. 24 (25) H.
When night reduction is active, NR appears after the
brackets, e.g. 24 (25) NR
i
The radiator thermostats must
always be fully open and operating
correctly when the system is tuned.
*Only applies to CTC EcoLogic L.
4.3.1 Setting without a room
sensor
If the room sensor is not installed (this can be selected
from the "Installer/Defi ne/Heating Circuit" menu), the
room temperature is adjusted here.
Adjustment if it is too cold indoors
Increase the "Curve inclination/Curve adjustment" value
by a couple of degrees.
Adjustment if it is too warm indoors
Reduce the "Curve inclination/Curve adjustment" value
by a couple of degrees.
i
Wait 24 hours to see if any further
adjustment is required.
The above menu shows Heating circuit 1 with a room sensor
and Heating circuit 2 without a room sensor.
If the outdoor temperature is below zero degrees, "Curve
inclination" is displayed (as shown in this example for Heating
circuit 2).
If the outdoor temperature is above zero degrees, "Curve
adjustment" is displayed.
