GENERAL REQUIREMENTS
Strictly follow the directions outlined in this manual:
• This system must be installed by a qualified technician.
• Verify that the units to be controlled have been installed according to the manufacturer's requirements and operate
correctly before installing the Airzone System.
• Locate and connect all the devices of the installation in accordance with the electronic regulations in force.
• Verify that the air conditioning installation to be controlled is in accordance with the regulations in force.
• It is necessary to use a Blueface Thermostat to have all the features of the Airzone system.
• Follow these recommendations to locate the thermostats:
• Perform all the connections with total abscense of power suppliance.
• In order to connect the elements of the system, use a proper cable cable: shielded twisted pair cable formed by 4 wires:
2x0,22 mm
2
+ 2x0,5mm
2
.
• Do not place the system bus close to lines of force, fluorescent lights, LED lamps, motors, etc. It might cause
interference on the communications.
• Respect the connection polarity of each device. A wrong connection may seriously damage the product.
• For elements externally powered at 110 /230 Vac, for the communications, it is only necessary to connect the poles "A"
and "B" of the bus.
• For elements externally powered at 110/230 Vac, respect the connection polarity. A wrong grounding may produce
electric shocks.
• According to the current local and national regulations, it is mandatory to add a switch (or other element to disconnect
the system) to the external supply wiring so that a constant separation between poles is guaranteed. The system will
restart automatically if the supply is eventually turned off. Use an independent circuit from the controlled system
for the power supply.
• Once the Airzone system is configured, verify that the static pressure of the duct system complies with the air
distribution network conditions where is installed (check the Manufacturer’s Manual of the equipment if you need to
modify this parameter).
