York YPAL 061, YPAL 050, YPAL 051, YPAL 060 manual TEST/UP Button, ADDRESS/DOWN Button, Alarm/Change

User Interface Control Center

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 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 first 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 five-seconds causes the network address to be displayed for two seconds.

Pressing this button three times within five-seconds resets 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 displayed 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 selected, 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.
