1. LonWorks Interface Overview
This interface is a communications interface for connecting
LonWorks to an air conditioner unit control network.
From the host connected to LonWorks, basic settings and
status monitoring is possible for up to 16 groups of A/C units.
Product Overview
•Up to 16 groups of indoor units (maximum 64 units) can be controlled with 1 LonWorks Interface unit.
For 17 or more groups of indoor units, connect additional interface units.
•Install a remote controller (or system controller, etc.), which can control the A/C units, to an inter-unit control
wiring other than the LonWorks Interface unit.
•Before making the connection to the LonWorks Interface unit, set the central control addresses in the indoor
units.

(*1) When a temperature above the upper limit of the temperature which can be set by the indoor units has been specified,
it will be set to the upper limit; conversely, when a temperature below the lower limit has been specified, it will be set to
the lower limit.
(*2) Two options can be selected using the setting switch from among remote-controller prohibit, fan speed setting, air
direction setting and filter sign.
(*3) When indoor units are under group control, an alarm is determined to have occurred when the alarm occurs at one or
more of the units.
(*4) The number of the indoor unit at which the alarm has occurred is notified. This makes it possible to identify at which
indoor unit of the indoor unit group the alarm has occurred.
(*5) When indoor units are under group control, the room temperature of the main unit in the group is notified.
(*6) When an alarm occurs at one or more indoor units, the alarm code is notified as the indoor unit status.
(*7) All the data which can be output is output at the set interval.
(*8) The same data is not output continuously at the set interval.

3. Assigning Central Control Addresses
(1) Turn the power switch (S001) on the LonWorks Interface
power board to OFF.
(2) Turn the setting switch (S006-2) to OFF (so that central
control addresses are set with the DIP switches).
(3) Set the first central control address with the address switch
(S005). When assigning serial numbers, a consecutive series
of numbers is assigned for the central control addresses.
<Example> If the first central control address is “5,” then this
circuit board assigns central control addresses “5,”
“6,” “7,” and “8.”
(4) Make the enable/disable settings with the indoor unit enabling
switches (S004).
<Example> If central control addresses “6” and “8” do not exist,
enable only “5” and “7.”
(5) Turn the power switch (S001) on the LonWorks Interface
power board to ON.
•Before assigning central control addresses for the
LonWorks Interface, use the remote controller to make
central control address settings for A/C units.
•Follow only the steps for "Assigning Central Control
Addresses" when a system controller or other central
controller is already provided.

network input SNVT_temp_p nviSetpoint_01;
network input SNVT_temp_p nviSetpoint_02;
network input SNVT_temp_p nviSetpoint_03;
These input network variables are used to change the indoor unit
temperature setting.
If the temperature setting is only changed from an A/C unit side (as
with the remote controller), then it is not necessary to use these
network variables.
