T7560A,B,C Digital Wall Module
HONEYWELL EXCEL 5000 OPEN SYSTEM
SPECIFICATION DATA
GENERAL
The T7560A,B Digital Wall Modules (DWM) display and
provide space temperature, setpoint, Occupied/Unoccupied
override, and fan mode/speed selection for the Honeywell
Excel 10 W7750, W7751, W7752, W7753, W7761, W7762,
W7763, and Excel 600, 500, 100, 50, 20 Controllers, as
applicable (a software module ModAL is available to adapt
the wall module to the respective Excel 20, 50, 100, 500, 600
controller. See T7560A,B,C Installation Instructions (product
literature no.: EN1B-0146GE51) for details.
Using the three buttons, the user can change room
temperature setpoint, fan mode/speed, initiate/cancel bypass,
and change configuration information such as the DWM’s
engineering units.
The T7560C Digital Wall Module (see inset above) has no
user interface (e.g. LCD, buttons, or setpoint dial) and issues
only temperature and humidity values.
These wall modules are not compatible with Honeywell
W7751A,C,E,G (VAV1) and W7752D1 (FCU1) Controllers.

Temperature Sensor Accuracy
The DWM is furnished with a 20kΩNTC temperature
sensor that follows a specific temperature-resistance curve.
See Fig. 1. Honeywell controllers used with the DWM
employ an algorithm that provides readings close to the
actual temperature. Table 2 summarizes the DWMsensor
accuracy for normal operating temperatures. Across the
range of 43 to 104°F (6 to 40°C), the accuracy is better
than ±0.75°F (±0.42°C).

General
The T7560A and T7560B feature three buttons, a setpoint
dial, and the LCD display (see Fig. 2). This section describes
the functions of these elements. Table 7 shows the functions
available with the different Excel 10 Controllers.
Fig. 2. Control elements of DWM.
NOTE:
If not specified differently, the graphics given below
show example display settings; depending on
configuration, the actual indications may vary from
those shown hereinafter.
Set Temperature
Depending on the configuration, you can adjust the
temperature within the limits given below:
°C absolute
⇒
12 to 30°C (in 0.5 steps)
°C relative
⇒
-5 to +5 (in 0.5 steps)
°F absolute
⇒
55 to 85°F (in 1.0 steps)
°F relative
⇒
-10 to +10 (in 1.0 steps)
Turn the SETPOINT DIAL
up/down to decrease/increase
the room temperature setpoint.
The display toggles the setpoint
value (either relative or absolute,
as configured).
After the new setpoint has been
set, the display returns to normal
mode after approx. 5 sec.
Set Fan Speed
The manually set fan speed is represented by a bargraph.
Depending on configuration, the fan speed can be set as
follows:
Three-speed fan override
⇒
AUTO, OFF, 1, 2, 3
Two-speed fan override
⇒
AUTO, OFF, 1, 2
Fan mode override
⇒
AUTO, OFF, ON
NOTE:
The default setting after power-up is AUTO. The
manually set fan speed overrides the controller’s
control algorithm.
Three-speed fan override
Press the FAN OVERRIDE button to toggle between:
AUTO
(fan speed from controller)
MANU OFF
(fan off)
With this setting, depending on
configuration, the display may
also read:
MANU 1
(fan speed 1)
MANU 2
(fan speed 2)
MANU3
(fan speed 3)
Two-speed fan override
Press the FAN OVERRIDE button to toggle between:
AUTO (fan speed from controller; display: see above)
MANU OFF (fan off; display: see above)
MANU 1 (fan speed 1; display: half bargraph)
MANU 2 (fan speed 2; display: full bargraph)
Fan mode override
Press the FAN OVERRIDE button to toggle between:
AUTO (fan speed from controller; display: see above)
MANU OFF (fan off; display: see above)
MANU ON (fan on; display: full bargraph)

With this setting, depending on
configuration, the display may
also read:
Humidity Display
If applicable, the humidity is indicated by the bargraph at the
top of the LCD. Each segment of the bargraph represents 4%
of relative humidity:
NOTE:
Humidity display is not available with fan control.
Humidity mode
(e.g. left 12 segments ON =
50% relative humidity)
Set Bypass/Occupancy Mode Display
The bypass function can be used to override the control
algorithm generated by the controller (e.g. for an event after
normal office hours, or for a room known to be unused).
The status of the occupancy mode can be seen from the sun,
moon, and snowflake symbols. The following LCD behaviors
are possible, depending on configuration. See T7560A,B,C
Installation Instructions (product literature no.: EN1B-
0146GE51) for configuration options:
Occupancy mode display for Excel 10 LCD signaling
