• To measure the outdoor temperature as accurately as possible,
the sensor must be positioned 2/3 of the way up the facade on
houses up to three storeys high. For higher buildings, the sensor
should be positioned between the second and third storeys. Its
location must not be completely protected from the wind but
not in a direct draft. The outdoor sensor should not be placed on
reflective panel walls.
• The sensor must be positioned at least 1 m from openings in the
walls that emit hot air.
• If the sensor cable is connected through a pipe, the pipe must be
sealed so that the sensor is not affected by outgoing air.
Then connect the sensor to the heat pump control system in
accordance with the instructions below.
1. Route the outdoor sensor connection cable through the cable
bushing in the top panel to the terminal block.
2. Connect the sensor to the terminal blocks according to the con-
nection diagram.
