JOHNSON CONTROLS

FORM 100.50-NOM6 (1207)

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.

When not in the program mode, if the Test/Up button 
is pushed and released once within fi ve 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 fi ve-
seconds a lock-out is released.  This serves the same 
function as temporally breaking the 24 VAC 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.

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 fi rst vacant communications address and changes its 
address to that address.  It will then display the address 
on the display for two seconds.  The controller is then 
connected to the network.

When connected to a network, pressing the button twice 
within fi ve-seconds causes the network address to be 
displayed for two seconds.

Pressing this button three times within fi ve-seconds 
resets the network address to one.

When this button is pressed and released one time within 
fi ve-seconds, it automatically scrolls through the fi ve 
alarms held in memory.  The fi rst alarm displayed is the 
latest and the last displayed is the oldest.

When this button is pressed and released twice within 
fi ve-seconds, it clears all alarms in memory.

When in the program mode and with a parameter 
selected, this button when pressed once causes the data 
value for that parameter to begin fl ashing.  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.

Table 6-2 shows the address for each control function 
as well as the unit of measurement for that function, the 
available range of adjustment and the factory setting as 
the unit left the factory.
