The dew point will vary depending on temperature and humidity. The
higher the humidity, the higher flow temperature is required to remain
above dew point and avoid condensation.
The condensation sensors will send a signal to the operating system
when they sense condensation and stop the cooling.
Instructions for installation and handling are included with the
condensation sensor.
7.18.1 Condensation monitoring, fan coils only
If only fan elements with drainage and condensation insulated pipes are
used, the flow temperature can be set to 7 °C. The lowest recommended
temperature is 10 °C for balanced cooling as the freeze guard is
activated at 5 °C.

Temperature sensor installation
The user interface in the delivery configuration automatically regulates
the flow temperature based on the outdoor temperature. A room
controller can be installed for greater comfort. If cooling mode is used, a
room controller is a must.
7.19.1 Room controller (accessories, see separate instructions)
▶ Install the room controller in accordance with its instruction.
▶ Connect the room controller to a terminal EMS on the installer
module in the heat pump module electric box.
▶ Set room controller CR10 as remote control before the installation is
put into operation (
Room controller's instruction). CR10H does
not have this option.
▶ Make circuit settings on the room controller before the installation is
put into operation (
Room controller's instruction).
▶ Indicate when the installation is put into operation that room
controller (CR10 or CR10H) has been installed (
a user interface for heating circuit 1.
▶ Make room temperature settings according to Chapter 12.3.2.
If there is already a connection on the EMS terminal, the connection is
made parallel to the same terminal in accordance with Fig. 16. If several
EMS modules are installed in the system, these must be connected in
accordance with Fig. 33, Chapter 8.12.

7.19.2 Flow temperature sensor T0
The sensor is delivered with the heat pump module.
▶ Fit the sensor in the pocket on the safety assembly (
on the buffer cylinder if one is installed.
▶ Connect flow temperature sensor T0 to terminal T0 on the installer
module in the heat pump module electric box.
7.19.3 Outside temperature sensor T1
The outside temperature sensor cable must meet the following minimum
requirements:
Cable diameter: 0.5 mm
2
Resistance: max. 50 ohm/km
No. of conductors: 2
▶ Install the sensor on the cold side of the house, normally north facing.
It must be protected from direct sunlight, ventilation air or anything
that can affect the temperature measurement. The sensor must not
be installed directly beneath the roof.
▶ Connect outdoor temperature sensor T1 to terminal T1 on the
installer module in the heat pump module electric box.
NOTICE:
Damage due to moisture!
Moisture may be transferred to surrounding materials if
there are gaps in the condensation insulation.
▶ Apply condensation insulation to all pipes and
connections up to the fan element for cooling.
▶ Use condensation insulation material that is
intended for condensation cooling systems.
▶ Connect the drain to the drain outlet.
▶ Do not use condensation guard.
If the room controller is installed after the system has
been put into operation, it must be selected as room
controller for heating circuit 1 in the start-up menu (
A screened cable must be used if the outside
temperature sensor cable is longer than 15 m. The
screened cable must be grounded in the inside unit. The
max. length of a screened cable is 50 m.
