CHECKING THE INITIAL CONFIGURATION
Check the following items:
1. AC unit-system communication: Set the Airzone system to an operation mode other
than Stop and turn on the zone to generate demand. Verify that the mode imposed on
the master thermostat appears on the indoor unit thermostat and that the set-point
temperature changes on the same.
2. AC unit-system communication: Set the Airzone system to Stop mode and verify that the
AC unit turns off and dampers open.
3. Opening/closing of the dampers and control outputs: Turn on and generate demand in
all the zones. Then turn each zone off and on to check that the associated control outputs
are correct.
4. Check that the static pressure in the ducted AC unit is in accordance with the conditions of
the airow distribution network in which it is installed (see the manufacturer's manual for
the AC unit if you need to modify this parameter).

SYSTEM PARAMETERS
• System address. (Not available on systems with BACnet gateway) This allows you to dene
the number of the system in your installation. By default, it displays the value 1. The system
will show the free address values with a maximum value of 99.
If you have address 1 and have an Airzone production control board (AZX6CCPGAWI) in the
installation, you can use the Supermaster function, which imposes the operation mode of
system 1 on the other systems connected to the AZX6CCPGAWI in a semi-forced way:
• Temperature range1.This allows you to select the maximum temperature for heating mode
(19 – 30 °C) and minimum temperature for cooling mode (18 – 26 °C), in steps of 1 °C. If you
want, you can disable any of the modes. By default, the maximum heating temperature is
set to 30 °C and the minimum cooling temperature to 18 °C.
• Combined stage1. (Only available in installations with AZCE6OUTPUT8 modules) This
allows you to activate/deactivate the combined stage of the "Control stages" parameter in
the user "Zone settings" menu.
• Hysteresis Cong1. This denes the temperature differential between the room
temperature and the set-point temperature to begin to apply the RadianT algorithm, which
aims to prevent underoor heating installations overheating. In installations with radiators,
set this value to 0 °C. By default, it is set to 0 °C.
• Type of opening*1. This allows you to enable/disable the proportionality of the system
dampers. Proportionality scales the opening or closing of the damper in 4 steps according
to the temperature demand of the zone, adjusting the zone airow rate. By default, it is set
to All/Nothing.
Operation mode of system 1 Available operation modes of the
other systems
*Note: Changing this parameter affects all motorized dampers in the installation. It is not
recommended for RINT and RIC smart grilles.
