1. INTRODUCTION AND GENERAL CHARACTERISTICS
Numerical displays DC-24 and DC.21 are temperature and humidity displays.
DC-24 displays admit form 1 to 5 sensors, calculating the
mean value of all them. It automatically detects the number of
sensors and displays its state once the display is initialized.
The temperature and humidity sensor is placed in a case that
permits a very easy installation using the support included in
the package. The recommended position of the sensor is at
1,7m from the floor. The display can include RS-485, Ethernet
or Wifi connectivity as options.
DC-25 displays are aesthetically identical to the DC-24 but do
not have sensor. They must receive the data from RS-485,
Ethernet or Wifi.

1.5. Display mounting
1.5.1. Mounting of the DC-24S and DC-25S.
The DC-24S and DC-25S displays can be fixed to the wall in two ways:
1–Hanged. Place 2 of the supplied plug at 410mm from one to the other. Insert the
screws leaving their head outside for 4mm. Hang the display using the upper-side zig-zag.
2–Screwed. Remove the methacrylate cover. Place the 4 supplied plugs at the distance
showed in the drawing. Place the 2 upper screws, leaving their head outside for 4 mm. Hang the
display using the upper-side zig-zag. Place the lower screws Tighten all the screws. Replace
the methacrylate cover.
The screws and plugs are provided with the display
