SPYDER MODEL 7 VAV CONTROLLER  INSTALLATION INSTRUCTIONS

Service Button
Fig. 5  Service Button Location
The service button is used to trigger dedicated events. It 
is important to distinguish different controller 
behaviors which are elicited depending upon whether 
the service button is pressed when the controller is 
powering up or when it is in normal operation. 
See the following dedicated events:
Pressing Service Button during Power-Up
The controller is reset to factory settings when you press 
the service button and turn it on (while the service 
button is pressed). The factory defaults are as follows:
• The application is cleared from the controller.
• The MAC address will be set to 0xFF (255), meaning 
that the controller will now search for a new MAC 
address (Auto MAC will be automatically triggered 
after controller power-up).
• The Max Master setting will revert to its default value. 
See Automatic MAC Addressing on page 25 for the 
default values.
• The max info frames will revert to 10.
• The device instance will revert to its default of 
4194302.
• The device name will revert to WEB-VAxxxx.
• The values of Auto MAC, Min MAC, and Max MAC will 
be reset to default.
• The Modbus, Ethernet, and Bluetooth settings will 
revert to their factory settings. The user settings for 
Modbus and BLE will be erased, the IP address will be 
reset to default, and the device will enter DHCP IP 
configuration.
Pressing Service Button during normal operation
During normal operation of the controller, a short press 
(< 1 sec) of the service button will cause a service button 
message (BACnet WhoAmI as a Private Transfer 
(SerialNo. = 130)) to be sent.
Refer to the Spyder Model 5 and Spyder Model 7 System 
Engineering Guide - 31-00282 for more information.
MOUNTING
To mount the Spyder Model 7 VAV, refer to the mounting 
instructions provided with the controller. Before 
mounting the controller on the damper shaft, review the 
power, inputs and output specifications. See 
Specifications on page 5.
Field devices driven by the analog current outputs must 
have a maximum resistance of 550 Ohms. The resistor 
must be installed on the field device.
NOTE:
Avoid mounting in areas where acid fumes or 
other corrosive vapors can harm the metal parts 
of the controller or in areas where escaping gas or 
other explosive vapors are present.
Before Mounting Actuator
Spyder Model 7 VAV controller includes a direct-
coupled actuator with the declutch mechanism, 
shipped hard-wired to the controller.
1. Determine the direction in which the damper shaft 
rotates to open the damper. Typically, there is an 
etched line on the end of the damper shaft that 
indicates the position of the damper.
