The outdoor sensor measures the outside temperature and, to a lesser degree, solar
radiation, the effect of wind and the temperature of the wall.
The sensor has a plastic casing with a removable cover. The connection terminals can
be accessed after removing the cover. Cable entry is either from the rear (concealed
wiring) or from below (surface-run wires). A cable entry gland PG11 can be screwed
into the bottom of the casing.
The sensor is used as a:
- Reference sensor for weather-dependent flow temperature control.
- Measuring sensor for optimization functions, value display or for connection to a
building management system.
