This type of actuator is for use on applications where the criteria of the RTN51..
standard versions are not satisfied. This actuator can be fitted in any position. The
sensing element must not be covered and it must not be affected by direct solar
radiation or air drafts.
In case of unknown conditions (especially in new buildings), it is always advisable to
use this version.
For comfort reasons, the sensing element should be located as shown in the following
illustration:
10 cm min.
1.2 m - 1.5 m
