2 Important information/Safety instructions
2.1 General safety precautions
Warning This appliance can be used by children aged 8
years and above, and by persons with reduced
physical, sensory or mental capabilities or lack
of experience or knowledge, provided that
they are supervised or have been instructed in
the safe use of the appliance and understand
the hazards involved. Children must not clean
or carry out user maintenance on the appli-
ance except under adult supervision.
Warning Ensure that children do not play with the
product.
Warning The installation must only be carried out by a
qualified installation engineer, following ap-
plicable rules and regulations in addition to
these installation instructions.
Caution Installation and connection should be carried
out in accordance with the instructions, in or-
der to avoid subjecting local residents to noise
disturbance.

Caution The cooling appliance must be mounted
hanging vertically on a wall. that can support
the gross weight of the heating appliance. The
central distance for mounting holes is 530
mm. Pipe installation is carried out according
to the diagrams.
N
To prevent leaks ensure that there are no
stresses in the connecting pipes!
N
It is important that the heating and brine cir-
cuits are completely bled after installation.
N
Bleed valves must be installed where necessa-
ry.
Caution Only spare parts approved by Danfoss Värme-
pumpar may be used for this appliance.

2.2 Electrical connection
Warning Hazardous electrical voltage! The terminal
blocks are live and can cause death through
electric shock. All power supplies must be iso-
lated before electrical installation is started.
The cooling module is connected internally at
the factory, for this reason electrical installa-
tion consists primarily of the connection of
the power supply.
Caution Electrical installation may only be carried out
by an authorized electrician and must follow
applicable local and national regulations.
Caution The installation may only be commissioned if
the heating system, water heater and brine
system have been filled and bled. Otherwise
the circulation pumps can be damaged.

3 Area of use
3.1 Area of use
The passive/active cooling module can be used for cooling requirements greater than what can be obtained
through only passive cooling (free cooling). For cooling requirements at max 20 kW.
The cooling modules make it possible to retain either passive or passive/active cooling from the rock –ground-
water collectors. The distribution system for this can be the radiator system (fan coils) or under floor heating
systems. Cooling starts when the outside temperature exceeds the set value for seasonal stop.

4 Installation
4.1 Dimensions and connections, Passive
The cooling module must be mounted vertically on a
wall. The central distance between holes is 530 mm.
Pipe installation is carried out according to the dia-

5 Configuration in the control system
5.1 Display description
Start screen
IMPORTANT! Requires Genesis software version 5.0 or later. Please note that a restart of the control system is
required for the installation to establish communication between the heat pump and the Expansion module.
This is indicated by the following icon in the display top bar (the same symbol is used in "Operating mode" in
the display to execute a restart):
To enable cooling control, navigate to “Cooling” in the
“Settings” menu in the display and turn on the
switches for“Enable passive cooling” and "Cooling
with expansion module 2". Set the parameters accord-
ing to the current installation. Confirm settings by
pressing the green tic in the bottom right corner. A re-
start is required.
1. Press on the Start screen to open the Menu
screen.
2. Press
3. Enter the code for installer access: 60,70,80.
4. Press on Settings .
5. Press to go to the menu page for cooling.
6. Press on the text Cooling.
7. Enable passive and/or active cooling depending
on what unit the end customer have.
8. Ability to change the seasonal cooling tempera-
ture. Factory settings: 25 oC)

5.2 Function during cooling operation
Cooling season integral
In order for Passive and Active cooling to start it is required that the heat pump is in cooling season. This is
determined by the seasonal cooling temperature setting and the outdoor temperature.
These two combined with time creates a cooling season integral. When the integral reaches the start-/stop lim-
it cooling season begins/ends. (From software 5.01)
▪Start limit cooling season integral: ≥100 (Upper limit: 300)
▪Stop limit cooling season integral: ≤-100 (Lower limit: -300)

Passive cooling
The user can choose to enable / disable passive cooling regardless of active cooling.
Passive cooling circulates the brine to the ground source. If another heating function has activated the com-
pressor, cooling from the evaporator will be credited in operating mode as "passive cooling".
Active cooling
The user can choose to enable / disable active cooling regardless of passive cooling.
In addition to passive cooling, active cooling will also use the compressor and evaporator to cool. The condens-
er heat that is created from cooling is used to fulfill other demands such as heat, pool, or tap water if possible, if
all demands are fulfilled, then the excess heat will be dumped into the ground source. The compressors RPM
when doing active cooling is controlled in a way that "brine out" has a set point that equals to the estimated
stop temperature for active cooling.
Start/Stop temperature Passive/Active cooling
Start temperature for passive cooling and stop temperature for active cooling is automatically calculated
from the start and stop temperature settings. . Start and Stop temperatures refers to the cooling supply line.
Example. Start temperature = 18°C, Stop temperature = 15°C.
1. Active cooling start (Start temperature cooling)
2. Passive cooling start (Calculated)
3. Active cooling stop (Calculated)
4. Passive cooling stop (Stop temperature cooling)
