Temperature transmitters
TRT5-420 and TRT5D-420 are wall mounted room transmitters for
temperature measurement.
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 towards 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.
