Humidity and temperature transmitters
HTRT10A-420 and HTRT10AD-420 are room transmitters for
measurement of humidity and temperature.
Installation
The transmitter should be mounted in a location with good air circula-
tion where it can be expected to give a representative reading. It may
be mounted on a wall-box or directly on the wall.
To remove the front cover, press the locking tounge in the lower part
of the casing using a 3 mm flat-blade screwdriver (see arrow in the
figure below). Press and twist the screwdriver and at the same time
pull the bottom part of the front outwards. When the bottom end of
the front is free from the bottom part of the casing, slide the cover to-
wards the top of the casing to free the hooks holding the upper edge
of the front cover.
To select the temperature scale °C or °F, set dip-switch 4 as shown in
the figure below.
