SECTION 6 – USER INTERFACE
If the program button is pushed while in the program
mode, the control will exit the program mode and store
any changed data even if the operator failed to press
the Alarm/Change button to accept any changes.
TEST/UP BUTTON
When not in the program mode, if the Test/Up button
is pushed and released once within five seconds, the
control skips any short cycle delays for one cycle. This
is a useful aid for the technician servicing the system
without having to wait for delays to time out.
If this button is pressed and released twice within five-
seconds a lock-out is released. This serves the same
function as temporally breaking the 24VAC circuit to
the Unit Controller.
When in the program mode this button scrolls up
through the parameter addresses.
See the Parameter
Points list to identify the desired parameter.
Parameters
are items that can be viewed and changed in the control
such as setpoints, year, date, time, time delays, etc.
ADDRESS / DOWN BUTTON
When in the program mode this button scrolls down
through the parameter addresses.
This button is also used to set the controller up on a
network. When wired to a network through the RS-485
terminals on the board, pushing this button once when
not in the program mode causes the control to scan the
communication bus. The control automatically locates
the first vacant communications address and changes
its address to that address. It will then display the ad-
dress on the display for two seconds. The controller is
then connected to the network.
When connected to a network, pressing the button
twice within five-seconds causes the network address
to be displayed for two seconds.
Pressing this button three times within five-seconds re-
sets the network address to one.
ALARM / CHANGE
When this button is pressed and released one time
within five-seconds, it automatically scrolls through
the five alarms held in memory. The first alarm dis-
played is the latest and the last displayed is the oldest.
When this button is pressed and released twice within
five-seconds, it clears all alarms in memory.
When in the program mode and with a parameter se-
lected, this button when pressed once causes the data
value for that parameter to begin flashing. At this point
the data value can be increased or decreased using the
Test/Up and Address/Down buttons. When pressed
again the current data setting is accepted and stored.
CHARACTER DISPLAY ADDRESSES AND
CODES
shows the address for each con-
trol function as well as the unit of measurement for that
function, the available range of adjustment and the fac-
tory setting as the unit left the factory.
