T7560A,B,C Digital Wall Module

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

), 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.

Fig. 2. DWM disassembly (T7560C)

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.

Terminals

1 = Common

2 = Temperature sensor

3 = Setpoint (T7560C: Do not connect!)

4 = Bypass/fan* (T7560C: Do not connect!)

5 = LED input (T7560C: Do not connect!)

6 = Bypass** (T7560C: Do not connect!)

7 = Humidity output

8 = 24 Vac / 22 Vdc input

* With Excel 10 Controllers:

** With Excel 10 Controllers:

W7751 (VAV), W7762 (HYD), and

W7763 (CHC)

For W7753 (UV) and W7761 (RIO),

see below.

NOTE

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).

T7560A,B,C DIGITAL WALL MODULES

EN1B-0146GE51 R0308A

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

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

) with a minimum of 18 AWG

(1.0 mm

) 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.

CONFIGURATION (T7560A,B)

After installation, the T7560A,B DWM must be configured in

order to perform as desired. This is done by using the buttons

and the setpoint wheel (see Fig. 7).

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)

•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.
