9.1.3 Damper Test Mode

Damper Test Mode gives the user the ability to open
specific dampers to verify the dampers are performing
properly. Each damper can be driven independently or in
any combination. The blower will operate during an active
damper test. The blower speed is determined by the sum
of the Zone Size's of each damper selected to be tested.
Damper Test Mode will automatically timeout after 30
minutes or immediately if "Stop" is pressed.
Upon entering Damper Test Mode, all system operation
will stop and each damper will be driven full open. Once a
damper(s) is selected for test, the non-selected dampers
will be driven fully closed.

Within the Diagnostic screen are two items related to alerts:
• Current Alerts – Alerts which are currently active
• Alert History – Cleared Alerts (last 30 days)

is when the alert was asserted. For Alert History the date/

9.3.2 Summary Table

The 1050 Control has a Summary Table which lists all
the communicating devices that have been discovered.
In addition to viewing the status of each communicating
device, the Summary Table can be used to remove "offline"
devices. The screen is made up of three fields:
• Device Information: Lists the device name and model/
serial number
• Enabled: Identifies whether the device has been
enabled
• Status: Identifies whether the device is currently
reporting on the bus (Only "Offline" devices can be
removed)
The Enabled and Status field can be used to troubleshooting/
informational purposes:
• Enabled + Online: Device has been enabled and is
currently reporting on bus
• Enable + Offline: Device has been enabled but is not
reporting (Err.126.00 will typically be triggered during
this condition).
• Disabled + Online: Device has not been enabled but
is reporting (verify device has been configured in the
installer settings).
• Disabled + Offline: Device has not been enabled and
is currently not reporting.
