Advanced Pendant Control
Operation of Pendant (continued)
The first task to do when first using the Advanced
Pendant Control on a Therm-O-Flow Plus system is to
ensure the number of zones of the system are config-
ured properly within the pendant. This tells the pen-
dant how many zones are there to communicate with.
The second task is to tell the pendant which zones are
ACTIVE and which are UNUSED. An example of this
is a 6 Zone Therm-O-Flow Plus unloader assembly.
Zone # 1 is dedicated to the FOLLOWER PLATE,
Zone #2 to the PUMP. Zones #3, #4, #5 and #6 can be
used as needed. If for example Zones #5 and #6 are
unused, the pendant needs to know that these are
UNUSED. This lets the pendant know that sending
commands and setting SV temperatures are not
needed because there are no devices connected to the
zone. Place the zone in STOP mode manually and the
pendant will not try to communicate with it.
NOTE: All zones must be properly setup for commu-
nications. This includes the proper address, baud rate,
parity, data bits and stop bits. This is always done
from the factory. If for some reason communication
errors exist with the pendant to the temperature con-
troller zones, reference manual 309100, section Check
Communication Parameters. Zone #1 is address 1,
zone #2 is address 2, etc.
To configure the zones properly in the pendant, pro-
ceed to the SETUP selection, enter the correct pass-
word and CHG the Configured Zones.

Change the configured zones to match the total num-
ber of zones of the Therm-O-Flow Plus system. Do
this by pressing F4 (CHG), and using the numeric keys
to enter the correct number of zones. Press ENTER
when done editing the zones. Press F1 (BACK) to
return back to the MAIN screen.
NOTE: While in any screen other than the MAIN
screen, all screens (except EDIT DATE/TIME) will time
out and proceed to the previous screen when no
activity is seen on the keypad. This forces the pen-
dant to maintain communication operations that hap-
pen while in the MAIN menus screen. The screens will
automatically timeout, returning to the previous screen
until it reaches the MAIN screen.
