Setup

BAUd RAte SeLeCtion
The SZ2165 must be programmed
using a PC and TCS Basys Controls
-
software. A communication baud
PA
rate must be set by placing one
VA
jumper in the area shown. This
baud rate must be the same for all
devices.
XMTR
For a 4.8K baud rate.
For a 9.6K baud rate.
For communication wiring, use twisted, shielded 18
1
AWG. Must be run separately.
24 VAC transformer. See powering instructions.
Sensor input wiring 18 AWG, twisted, shielded pair.
Dry contact. Must not be powered.
For a 19.2K baud rate.
External relay. 24 VAC Coil

Programming

The SZ2165 must be programmed with a PC. A jack on the face
allows local access for programming. If you plan to program the con-
troller while it is on a network, prior to putting the controller on the
network, a unique address must be set in the controller by accessing
it through the port on the front.
For more information on programming using a PC and the
TCS Insight software, consult your TCS software manuals.
ContRoLLeR AddReSS
The factory default
address for an SZ2165 is
165 . On the "Network>
Poll" tab, right click on
the desired controller and
select "Change Address
from the menu that appears. Next, select the desired address from
the use the drop-down menu and hit ENTER. Finally, click "Yes" in
the Change Controller Address window that appears.
inteRnAL time CLoCK
On the "Schedules>
Date and Time" tab, you
can see and modify the
controller's time (military
time), day of the week,
date and year. Click on
"Read" if you would like to see the current time, day of week and
date in the controller. Click on "To PC Time" read these parameters
from your computer instead and automatically program them into the

On the "Schedules>
Schedules" tab there
are two occupied time
periods per day, and thus
two time schedules (A
and B). Let us say that
the occupied time for
a particular day is from
8:00AM to 12:00PM and
from 1:00PM to 5:00PM.
In the "A" schedule you
could enter 8:00 to 12:00,

and in the "B" schedule
you could enter 13:00 to
17:00. You can reverse
the "A" and "B" sched-
ules also. You can also
enter 8:00 to 17:00 for the "A" schedule and 0:00 to 0:00 for the "B"
schedule. 0:00 (12:00AM)starts the day, and 24:00 (12:00AM) ends
the day. Note: occupied times that span midnight have to be coordi-
nated using two days' time schedules.
NOTE: The start of an occupied period is delayed by the
power-on delay value.

On the "Schedules>
Holiday" tabs the holiday
schedules set which days
in a year will use Holiday
1 & Holiday 2 schedules
as defined. Each holiday
consists of a month
and date, as well as the
number of days that the
holiday will be in effect.

The "Monitoring" tab
displays the current tem-
peratures and the status
of all inputs and outputs.
These values are auto-
matically read when
accessing this tab initially
and are automatically
refreshed periodically
while viewing the tab. By
right clicking on a particu-
lar point, you can view
a live graph of that point
over time.
