HONEYWELL EXCEL 5000 OPEN SYSTEM
INSTALLATION INSTRUCTIONS
BEFORE INSTALLATION
All wiring must comply with local electrical codes and
ordinances or as specified on installation wiring diagrams.
Digital Wall Module (DWM) wiring can be sized from 16 to 22
AWG (1.5 to 0.34 mm
2
), depending on the application. The
max. length of wire from a device to a DWM is 164 ft (50 m).
Twisted pair wire is recommended for wire runs longer than
100 ft (30.5 m).
CAUTION
EMI Noise Introduction.
Risk of erratic system operation.
Keep wiring at least one ft (305 mm) away from large
inductive loads such as motors, line starters, lighting
ballasts and large power distribution panels. During
installations, try to avoid areas of high EMI noise.
Run DWM wiring separately from 50 Vac or greater
power wiring.
WARNING / CAUTION
Risk of electric shock or equipment damage!
►Do not touch any live parts inside the DWM housing.
►Disconnect the power supply before making connections
to or removing connections from the DWM's terminals.
►Do not reconnect the power supply until you have com-
pleted the installation.
►If the DWM is powered via terminal 8 and connected to
earth ground, then the cable must be shielded.
►Observe precautions for handling electrostatic sensitive
devices.

NOTE: A software module (ModAL module GNRSC02A) is
available to adapt the DWM to the respective Excel
20, 50, 100, 500, 600, or 800 controller, making any
further configuring obsolete. Contact your local
Honeywell distributor for further details.
DWM DISASSEMBLY
The T7560A,B,C comes packed with a sub-base that mounts
separately for ease of installation. The cover is fixed by a
latch on the underside of the unit. Remove the cover as
shown in Fig. 1 (T7560A,B) or Fig. 2 (T7560C):
1. Insert the tip of an awl or a similar narrow, pointed object
into the small hole in the latch (T7560A,B) or simply
depress the latch by hand (T7560C).
2. Pry off the cover.

INSTALLATION
Mount the DWM on an inside wall approximately 54 in.
(1.3 m) from the floor (or as specified on the installation
drawings) to allow exposure to the average zone temperature.
Do not mount the DWM on an outside wall, on a wall
containing water pipes or near air ducts. Avoid locations that
are exposed to discharge air from registers or radiation from
lights, appliances, or the sun.
The DWM is furnished with a terminal block; all field wiring
connections are made to these eight terminals.
The DWM has to be mounted in vertical position with the LCD
display to the top.
Mount the subbase directly on a wall (see Fig. 3) using the
type of screws appropriate for the wall material.
Fig. 3. Mounting of DWM (T7560A,B shown)
See Fig. 6 for T7560A,B,C mounting dimensions.
Wiring
Wire the terminal blocks as follows:
1. Strip 3/16 in. (5 mm) of insulation from the conductor.
2. Insert the wire in the required terminal location and tighten
the screw to complete the termination.
IMPORTANT
Deviation from this rule can result in improper
electrical contact. See Fig. 4.
3. Verify DWM is wired according to Fig. 4.
NOTE: For specific wiring requirements, see the following
Power section.

Fig. 4. Wiring of DWM
NOTE: If connected to W7753 (UV) Controller, both
terminals 4 and 6 must be connected.
W7761 Remote I/O Controller supports only
terminals 2 (temperature), 7 (humidity), and
1 (common), as well as terminal 8 as voltage supply.
Wiring with terminal 8 is not necessary if:
a) An FCU or CHC controller with software is
connected (see table 2).
b) An Excel 500 with 6V/8V/10V signaling from the
controller is used.
c) The T7560A is then powered by terminal 5.
Power
The DWM can be powered as follows:
•T7560A: preferably via the 5 V LED input (terminal 5); via
terminal 8 is also possible
•T7560B,C: via the 24 Vac/dc input (terminal 8).
IMPORTANT
The DWM can be powered only via terminal 5 with
those controllers listed in Table 2, and if a
SW version listed in Table 2 or higher is installed.
If the DWM is powered via terminal 5, the Excel 10
controller must be configured for LCD_DISPLAY
(LED output continuously ON).
NOTE: The 24 Vac power supply is needed only with the
T7560B,C DWM (for the humidity sensor).

Alternatively, a DC voltage source with 5...15 V can
be connected to terminal 5 (see IMPORTANT note
above).
Alternatively, a DC voltage source with 18...30 V
(e.g. 22 Vdc from W7750 CVAHU) can be connected
to terminal 8.
Input ratings
Terminal 5:
min. 5 Vdc I
max
3 mA
max. 15 Vdc I
max
4 mA
or LED output of any Excel 10 controller
Terminal 8:
24 Vac from controller; I <6 mA
or
18 Vdc (I <2.4 mA) ... 30 Vdc (I <10 mA)
Controllers with the following output ratings can be connected
to terminal 5
(ratings are met by all Excel 10 controllers):
•5 V with 389 Ω
•4.3 V with 100 Ω
•14.3 V with 1.5kΩ
Use up to 16 AWG (1.5 mm
2
) with a minimum of 18 AWG
(1.0 mm
2
) wire for connecting 24 Vac power to terminal 8.
CAUTION
Low Voltage Equipment.
Risk of equipment damage.
The 24 Vac power source for the DWM must be a
Class II Power Source. To conform to Class II
restrictions, transformers must not be larger than
100 VA. A transformer that is CE certified and meets
the Low Voltage Device (LVD) requirements must be
used in Europe for all installations of this product.
The DWM power usage is <0.2 VA at 24 Vac. The DWM
does not require a dedicated transformer. The DWM can get
power from any convenient location in the 24 Vac power
circuit.
The 24 Vac power can come from the 24 Vac power terminals
on the nearest controller or directly from a 24 Vac
transformer, whichever is closer.
When all wiring is complete, attach the cover of the DWM as
is shown in Fig. 5.
NOTE: Make sure that the latch on the underside of the
DWM engages properly.

Normal Operating Mode
After the DWM is powered up by the controller, it will display
the room temperature and will operate as configured by
default; the respective default setting is marked with an
asterisk in the following.
After power-up, all display segments are switched on for
approx. one second (see Fig. 8).

P7 Temperature offset
* Temperature offset; values of 0 through 99
are valid. 50 = no change (default),
49 = -0.1 °C, 51 = +0.1 °C, etc.
This offset varies the LCD display value, only.
It must be set separately in the XL10 controller.
P8 Switch back fan / temperature offset if unoccupied
*enable FAN Key / enable Setpoint Key
•enable FAN Key / disable Setpoint Key
•disable FAN Key / enable Setpoint Key
•disable FAN Key / disable Setpoint Key
To "disable" means to switch back to FAN= auto / Setpoint
offset = zero and disable operation.
To "enable" means to make normal operation possible (no
action if unoccupied).
"Unoccupied" means:
•Effective Unoccupied (moon on continuously)
or
•Override Unoccupied (moon flashing).
Works only with configuration P4:1: LCD signalling
Setpoint will be set to zero only if set to relative: P1:1 and
P1:3.
P9 Limit setpoint
•-
Limit setpoint to ±0 … 5 °C (if set to Celsius) or to
0 … 9 °F (if set to Fahrenheit).
Default (if set to Celsius):
Default (if set to Fahrenheit):
Example (units set to Celsius): A setting of
means that the set point offset is limited to -3 to +3 °C.
Example (units set to Fahrenheit): A setting of
means that the set point offset is limited to -8 to +8 °F.
PA Limit for humidity low limit output value
•-
Limit the output value to 10 … 20% relative humidity in
steps of 5%.
This affects the output voltage on pin 7, only, and has
no effect upon values appearing in the display.
= 10%, = 15%, = 20% (default).
How to Check the Software Version
Press the left and right button for approx. 5 seconds: After a
LCD display test, you will see the current SW version of the
device.
