Test/Up Button; Address/Down Button; Alarm/Change; Character Display Addresses & Codes - York Eco 2 Quick Start Up Manual

TEST/UP BUTTON

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.

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 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.
28
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.

ALARM/CHANGE

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.
