7.2.3 Additional Outdoor air temperature probe for Climatic curves
If the positioning of the HP unit is non-representative to measure the Outdoor air temperature for a correct
calculation of the water set point by Climatic curve, an additional temperature probe can be provided.
Additional Outdoor air temperature 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 2.5m above the ground or at most
half way up the house.
With additional Outdoor air temperature probe and Par5109=1 (enable), the detected temperature is applicable to
the followings;
7.2.2 Climatic curve
8.2.3 Heat pump + DHW heater
8.3.1.2 Depends on Outdoor air temperature
8.3.2 Backup heater in supplementary mode
