• for the serial connection use three-wire shielded cable, AWG 20-22. The
length of the network must not exceed 500 m. For extended networks
fi t a 120 Ohm resistor between RX/TX+ and RX/TX- on the fi rst and last
device, to avoid possible communication problems.
Assembly for the fl ush mounting
To fi t the rear part of the terminal use a fl ush mount box with a min.
diameter of 65 mm and a minimum depth of 31 mm.
1. Detach the front from the rear of the thT thermostat using a
screwdriver;
2. Make the electrical connections according with the schematic;
3. Fasten the rear to the fl ush mount box using the 2 screws supplied:
4. Finally reposition the thT thermostat the original position and ensure
to fi x it with clicks into place.
