Important information

This accessory, which includes an independent electrical
control module, is used when your climate unit is in-
stalled in a building with several climate systems1requir-
ing different supply temperatures; for example, when
the building has both a radiator system and an underfloor
heating system. See “Compatible products” below to
see which climate units ECS 40/ECS 41 can be connec-
ted to.
The total water flow in the climate systems should not
exceed 1,700 l/h.
Caution
With underfloor heating systems, maximum
supply temperature for heating is normally be
set between 35 and 45°C.
Check the max temperature for your floor with
your floor supplier.
Caution
If the room sensor is used in a room with un-
derfloor heating, it should only have an indicat-
ory function, not control of the room temperat-
ure.

Mounting
Caution
The screw type must be adapted to the surface
on which installation is taking place.
UN
Use all mounting points and install the module upright,
flat against the wall, with no part of the module protrud-
ing beyond the wall.
Leave at least 100 mm of free space around the module
to allow access and make cable routing easier during
installation and servicing.
NOTE
The installation must be carried out in such a
way that IP21 is satisfied.

Connection of extra
climate system
When connecting extra climate systems, they must be
connected so that they have a lower temperature than
the normal climate system.
Circulation pump and
mixing valve
The extra circulation pump (GP10) is positioned in the
extra climate system according to the outline diagram.
The shunt valve (QN25) is located on the supply line
after the heat pump/indoor module, before the first radi-
ator in the climate system 1. The return line from the
extra climate system connects to the shunt valve and
to the return line from the climate system 1, see outline
diagram.

NOTE
All electrical connections must be carried out
by an authorised electrician.
Electrical installation and wiring must be carried
out in accordance with the stipulations in force.
The climate unit must not be powered when
installing ECS 40/ECS 41.
• To prevent interference, sensor cables to external
connections must not be laid close to high voltage
cables.
• The minimum area of communication and sensor
cables to external connections must be 0.5 mm² up
to 50 m, for example EKKX, LiYY or equivalent.
• ECS 40/ECS 41 must be installed via an isolator
switch. The cable area has to be dimensioned based
on the fuse rating used.
• Mark the relevant electrical cabinet with a warning
about external voltage, in those cases where a com-
ponent in the cabinet has a separate supply.
• ECS 40/ECS 41 restarts after a power failure.
The electrical circuit diagram is at the end of this Installer
handbook.

CONNECTING TO HEAT PUMP OR INDOOR
MODULE
ECS 40/ECS 41 contains an accessory board (AA5) that
connects directly to the main product’s PCB (terminal
block AA2-X30).
If more accessories are to be connected, or are already
installed, the boards are connected in series.
Because there can be different connections for accessor-
ies with accessory board (AA5), you should always read
the instructions in the manual for the accessory that is
to be installed.

Program setting of ECS 40/ECS 41 can be performed
via the start guide or directly in the menu system.
Start guide
The start guide appears at first start-up after installation
of the heat pump/indoor module, but is also found in
menu .7.7.
Menu system
MENU 7.2.1 - ADD/REMOVE ACCESSORIES
Add or remove accessories here.
Select: "Climate system 2-8".
MENU 1.1 - TEMPERATURE
You make temperature settings for your installation here.
MENU 1.3 - ROOM SENSOR SETTINGS
Here, you make your settings for room sensors and
zones. The room sensors are grouped by zone.
MENU 1.30.1 - CURVE, HEATING
Curve, heating
Setting range: 0 – 15,0
In menu "Curve, heating" you can view the heating curve
for your house. The task of the heating curve is to
provide an even indoor temperature, regardless of the
outdoor temperature. It is from this heating curve that
ECS 40/ECS 41 determines the temperature of the water
to the climate system, the supply temperature, and
therefore the indoor temperature. Here, you can select
heating curve and read off how the supply temperature
changes at different outdoor temperatures.
TIP
It is also possible to create your own curve.
This is done in menu 1.30.7.
Caution
With underfloor heating systems, the maxim-
um supply temperature is normally set
between 35 and 45 °C.
Check the max floor temperature with your
floor supplier.
TIP
Wait 24 hours before making a new setting,
so that the room temperature has time to sta-
bilise.
If it is cold outdoors and the room temperature
is too low, increase the curve slope by one in-
crement.
If it is cold outdoors and the room temperature
is too high, lower the curve slope by one incre-
ment.
If it is warm outdoors and the room temperat-
ure is too low, increase the curve offset by one
increment.
If it is warm outdoors and the room temperat-
ure is too high, lower the curve offset by one
increment.
MENU 1.30.3 - EXTERNAL ADJUSTMENT
Climate system
Setting range: -10 – 10
Setting range (if room sensor is installed): 5 – 30 °C
Connecting an external contact, for example, a room
thermostat or a timer allows you to temporarily or peri-
odically raise or lower the room temperature. When the
contact is on, the heat curve offset is changed by the
number of steps selected in the menu. If a room sensor
is installed and activated the desired room temperature
(°C) is set.
MENU 1.30.4 - LOWEST SUPPLY HEATING
heating
Setting range: 5 – 80 °C
15Chapter 6 | Program settingsECS 40/ECS 41
S
Program settings

Set the minimum temperature on the supply temperat-
ure to the climate system. This means that
ECS 40/ECS 41 never calculates a temperature lower
than that set here.
MENU 1.30.5 - LOWEST SUPPLY COOLING
cooling
Depending on which cooling accessory is used, the
setting range can vary.
Setting range 7 – 30 °C
Alarm, room sensor during cooling operation
Setting range: on/off
Set the minimum temperature on the supply temperat-
ure to the climate system. This means that
ECS 40/ECS 41 never calculates a temperature lower
than that set here.
Here, you can receive alarms during cooling operation,
for example if a room sensor malfunctions.
NOTE
Cooling flow line must be set with regard to
which climate system is connected. For ex-
ample, floor cooling with too low cooling flow
line can cause condensation precipitation,
which in the worst instance could lead to
moisture damage.
MENU 1.30.6 - HIGHEST SUPPLY HEAT
climate system
Setting range: 5 – 80 °C
Here, you set the highest supply temperature for the
climate system. This means that ECS 40/ECS 41 never
calculates a temperature higher than the one set here.
Caution
With underfloor heating systems, "Maximum
supply temperature for heating" should nor-
mally be set between 35 and 45°C.
Check the max floor temperature with your
floor supplier.
MENU 1.30.7 - OWN CURVE
Own curve, heat
Caution
Curve 0 must be selected for own curve to
apply.
You can create your own heating curve here, if there
are special requirements, by setting the desired supply
temperatures for different outdoor temperatures.
Supply temp
Setting range: 5 – 80 °C
Own curve, cooling
Caution
Curve 0 must be selected for own curve to

You can create your own cooling curve here, if there are
special requirements, by setting the desired supply
temperatures for different outdoor temperatures.

Setting range: 10 – 300 s
The shunt amplification and shunt waiting time for the
different extra climate systems that are installed are
also set here.
MENU 7.5.3 - FORCED CONTROL
Here you can force control the various components in
the installation. The most important safety functions
remain active however.
NOTE
Forced control is only intended to be used for
troubleshooting purposes. Using the function
in any other way may cause damage to the
components in your climate system.
Caution
Also see the Installer Manual for the relevant
heat pump.
