1. HARDWARE LAYOUT
¾
N-L-Earth:
Direct input with 230VAC-50Hz European Union standard voltage.
¾
T1:
6-wired input, for interconnection with the system’s thermostat. I t allows the
communication with the zone’s control on the demand/ no-demand state in order the
set-point temperature to be established.
¾

Type B Cable and in a tube separate from the rest of the cables connecting to the
electronic control panel.
2. POWER SUPPLY CONNECTION
The electronic control panel is supplied with 12Volts of direct current, supplied by a stabilized
Airzone source connected to the electricity supply with the European Union standard voltage
level: 230 volts of alternate current 50Hz.
