General
This accessory is used when your climate unit is installed
in buildings with several climate systems1that require
different supply temperatures, for example in cases
where 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 connected 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.

SETTING THE CIRCULATION PUMP
LEK
GP10-SF4
LEDs
I II III
The circulation pump (GP10) is equipped
with five LEDs. In normal mode, the
LEDs show the pump’s setting by light-
ing up in green and/or yellow. The LEDs can also indicate
an alarm, in which case they light up in red and yellow.
The circulation pump’s (GP10) various settings are se-
lected by pressing the switch (GP10-SF4).
Choose between 5 different settings on the circulation
pump.
• proportional pressure auto adapt (PPAA)
• constant pressure auto adapt (CPAA)
• proportional pressure (PP)
• constant pressure (CP)
• constant curve (CC).
The circulation pump’s factory setting is PP, speed 2.
PROPORTIONAL PRESSURE AUTO ADAPT
(PPAA)
The circulation pump continually regulates the flow
through the system with a great deal of freedom, to
ensure minimum pump power consumption.
The setting is intended for radiator systems. Due to
optimisation to low pumping capacity, the flow may be
insufficient in certain systems.

Program settings
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.
Here, you select the zone to which a sensor will belong.
It is possible to connect multiple room sensors to each
zone. Each room sensor can be given a unique name.
The control of heating, cooling, humidity and ventilation
are activated by ticking each option. Which options are
shown depends on which type of sensor is installed. If
control is not activated, the sensor will be the displaying
sensor.
Caution
A slow heating system such as underfloor
heating may be inappropriate for controlling
with room sensors.
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
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.

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
