8.2 Ordinary displayed data
a. Ordinary displayed data are displayed in all display pages.
b. If the unit system is under running state, i.e. one or more than
one Modular unit is under running operation, there will be a
dynamic display of . If the system is under OFF state, there
is no display.
c. If the communication with the main unit Modular unit is fail, it
displays E2
d. If it is under the host computer network control,
otherwise there is no display.
e. If it is under wired controller locked or button locked state, it
displays the lock mark. There will be no display after the lock
is unlocked.
8.3 Treatment of display data
The data display area is divided into Up area and Down area,
with two groups of two-digit half 7-segment digital display,
respectively.
a.Temperature display
Temperature display is used for displaying the total outlet water
temperature of unit system, outlet water temperature ,condenser
pipe temperature T3A of system A, condenser pipe temperature
T3B of system B, outdoor environmental temperature T4,
anti-freezing temperature T6 and setting temperature Ts, with
allowable data display scope -15℃～70℃. If the temperature is
higher than 70℃, it is displayed as 70℃. If there is no effective
date, it displays "— —" and indication point
b. Current display
Current display is used for displaying Modular unit system A
compressor current IA or system B compressor current IB, with
allowable display scope 0A~99A. If it is higher than 99A, it is
displayed as 99A. If there is no effective date, it displays "— —"
and indication point A is on.
c. Failure display
It is used for displaying the total failure warning date of unit or
that of Modular unit, with failure display scope E0~EF, E
indicating failure, 0~F indicating failure code. "E-" is displayed
when there is no failure and indication point
time.
d. Protection display
It is used for displaying the total system protection data of unit or
the system protection data of Modular unit, with protection
display scope P0~PF, P indicating system protection, 0~F
indicating protection code. "P-" is displayed when there is no
failure .
e. Unit number display
It is used for displaying the address number of the currently
selected Modular unit, with display scope 0~15 and indication
point # is on at the same time.
f. Display of online unit number and startup unit number
They are used for displaying the total online Modular units of the
whole unit system and the number of the Modular unit under
running state, respectively, with display scope 0~16.
Any time when the spot check page is entered to display or
change Modular unit, it is needed to wait for the up-to-date data
of the Modular unit received and selected by wired controller.
Before receiving the data, the wired controller only displays
"——" on the data display Down area, and the Up area displays
the address number of the Modular unit. No page can be turned,
which continues until the wired controller receives the
communication data of this Modular unit.

8.4 Query display
Press the "▲" or "▼" key of wire controller to adjust the main unit
serial number can query 16 sets main units' status information from
#0～#15. Press " " or "
number of one main unit then can query all the status information of
this unit.
