Setting the limit for the wind sensor measurement message.
You must set compensation area limits in volts. The minimum limit
indicates where in the emitter's measurement area compensation
begins and the maximum indicates at which measurement area the
compensation is at a maximum level. (To set the amount of
compensation see p. 6)

Measurement 6 can be used as a free temperature measurement,
Room temperature measurement, wind measurement or measurement of
the pressure in the heating or ventilation network. It is factory set as a free
temperature measurement labelled “Cold water”. The label for
Measurement 6 can be changed using the text editor.
0…10V transmitters are used in wind-/pressure measurements. In this
mode you can set the wind transmitter area that wind compensation occurs
at. The wind compensation temperature amount is set in Settings (see p.6).
A pressure transmitter can be used to set alarm limits for upper limit, fill,
and lower limit alarms.

E.g., the effect of wind compensation on supply water
A wind sensor is in use which has a measurement area of 0… 20m/s. You
want wind compensation to begin when the wind velocity is 6 m/s and
compensation to be at maximum value when the wind velocity is 14 m/s.
Wind compensation is set at 4°C (setting range -7 …7°C).
See the next page for instructions on setting the measurement area for the
network pressure and setting pressure alarms.
