Outside air probe (BT11) connection
The outside air probe allows the system water temperature set
point to be compensated during heating or cooling operation.
Installation instructions
The outside air probe must be installed:
• outside of the home
• not in direct sunlight, away from flue gas discharges, air
outlets, or doors and windows.
• on a perimeter wall facing north/north-west
• at a minimum height of 2.5 metres above the ground or at
most half way up the house.
Mounting method:
• Open the cover of the sensor by unscrewing the 4 screws.
• Attach a probe to the wall and the correct position as
described above.
• For the electrical connections see “Connection diagram”.
• Re-place the cover of the sensor.
Below is a list of the electrical connections that the installer needs to complete for the INSIDE MODULE only.
The maximum length of probe cables is 100 m for 1 mm2 cables, and 50 m for 0.5 mm

Water outlet and return temperature probe BT1 and
BT2 connection to heat pump
• Fit probes BT1 and BT2 in the probe sockets on the heat
pump outlet and return fittings using super-conductive
paste.
• Fasten the probes to the corresponding fittings using ties.
• Connect the probes to the inside module terminal block as
shown in the figure.
• Carefully insulate the entire area of the probe socket fit-
tings so as to prevent condensate or energy losses.
• If the probe cables need to be extended make sure the
extensions are positioned indoors or inside the heat pump.
