LEGEND
*An “X
“ in the Keypad Entry column indicates that the reading can be
forced by entering a value and then pressing
. The valid force ranges
are listed in the Expansion column.
†Applies to both inlet guide vanes and inverter (variable frequency drive).
NOTES:
1. Alarm no. will only be displayed if ALARM is present.
2. Alert no. will only be displayed if ALERT is present.
3. If unit is not configured for a certain subfunction, that subfunction will not
show up when scrolling through values.
If the display is ENT HGH and the user wants to use out-
door air, pressing
will change the display to ENT
LOW/FORCE 4; overriding or “forcing” the enthalpy status to
be good. This allows economizer operation.
Refer to Table 54 for more information on “forcible” dis-
plays. To discontinue a forced command, press the
key.
This removes the forced value and allows the unit to accept in-
put from the controlling device.
The forced values are useful for problem diagnosis, and as a
preliminary step before running the test function.
(Analog outputs) — This subfunction displays the sta-
tus of the various analog outputs. Press
to access addi-
tional analog outputs. Some outputs can be user forced by
entering a value for the output. For example, press
until
the HCV display appears. The display will indicate an output
value describing the heating coil valve percent open. If the dis-
play reads HEATING COIL VALVE 0 (valve closed) and the
user wants to use the heating coil, pressing
will change the display to HEATING COIL VALVE 100/
FORCE 4; overriding or forcing the heating coil valve to 100%
open. This is useful for problem diagnosis and as a preliminary
step before running the test function.
(Outputs) — This subfunction displays the vari-
ous system discrete outputs. These displays indicate the ability
of the component or device to operate. It does not indicate that
the component or device is functioning, but that the component
or device has been energized by the control. Press
to
access additional discrete outputs. Some outputs can be user
forced.
(Standby) — The Standby/Run mode indicates the
current capability of the unit. Press
to access Standby.
This displays either a STBY NO (unit is in the run configura-
tion) or STBY YES (unit is in standby and is not capable of
operating). To change from STBY YES to STBY NO, either
press
or
. To change from STBY NO to STBY
YES, press
. This change to STBY YES will clear any
alarms present on the unit.
Press
to view external clock input status. This status
indicates when the Remote Start/Unoccupied control of unit is
in effect. A 0 is displayed when there is no external input. A 1
is displayed when an external clock input is present.
