T7770C or D Wall Module Override LED

The remote override LED, located on either the T7770C or 

T7770D Wall Module will display the Manual Override mode of 

the controller. The modes are:

1.

LED = Off. No override active.

2.

LED = Continuously On. Bypass mode (timed Occupied 

override).

3.

LED = One flash per second. Continuous Unoccupied 

override.

4.

LED = Two flashes per second. Remote only, 

continuous Occupied override.

Step 3. I/O Tests

The controller can be configured using the L

ON

S

PEC

™, or 

E-Vision PC configuration tool. Once this is done, the 

W7751H can be commanded to MANUAL mode, and each 

output and input can be exercised/viewed to verify proper 

wiring connections and equipment operation.

W7751H Actuator Checkout

To check out the actuator on the W7751H, determine the 

direction the damper shaft moves to open the damper (CW or 

CCW). See Fig. 5.

NOTE: Devices for use only if used for Energy Management: 

Q7740A,B and Q7751A.

Devices for use on an Energy Management and/or Smoke 

Control:

— 14507287 Series Power Supplies,

— W7751B2010, W7751D2016, W7751F2011, 

— W7751H2025 Series 9, 

— W7761A2010, 

— Q7750, 

— Q9200, 

— XFL521, XFL522, XFL523, XFL524, 

— XL500, 

— XLINK.

Connect the controller with the laptop PC. To do this, the 

controller on the W7751H must be wired, powered, and 

connected to the portable PC via the SLTA. The SLTA 

connects to the controller on the W7751H via the Jack for 

Network Access on T7770 Wall Modules or by the B-Port on 

the Q7750A Zone Manager. From L

ON

S

PEC

™, or E-Vision 

Software, drive the actuator on the W7751H open and then 

closed. Observe the operation of the actuator; if the damper is 

closed, it should begin to open. If the damper is open, it 

should begin to close.

NOTE: Once finished programming, disconnect the portable 

PC.

If no movement is observed, check to see if 24 Vac is present 

at the controller on the W7751H. With proper wiring, 24 Vac 

present, and proper commands from the software, the 

actuator should operate properly. If not, the W7751H Smart 

VAV Actuator may need to be replaced.

Step 4. Verify Sequences of Operation

For the detailed descriptions of the sequences of operation, 

see the Excel 10 VAV System Engineering form 74-2949.
