▫
Connected (Green): The UbiquiSTAT
™
has detected a valid network connection. For BACnet MS/TP, this means
that the device has successfully joined the token ring.
▫
Troubleshoot (Yellow): The UbiquiSTAT
™
is able to communicate, but is detecting problems with the network that
may cause the communication to be unreliable. Check the RS-485 wiring and network con
fi
guration on other
devices.
▫
Disconnected (Red): The UbiquiSTAT
™
has not detected a valid network connection. For BACnet MS/TP this
means the device has not joined the token ring.
-
Activity
: There are two indicator lights; one for data received (Rx), and one for data transmitted (Tx). These lights
blink whenever data is received or transmitted to or from the device respectively. They are useful as a basic
diagnostic in determining whether data is
fl
owing across the network.
-
Rx Traf
fi
c
: This is a statistic that indicates how much network traf
fi
c has been received by the UbiquiSTAT
™
.
Shown are both the number of messages and the total number of bytes. This number should be increase whenever
the thermostat is monitored or programed via the network (Gateway and/or Ubiquity
TM
).
-
Tx Traf
fi
c
: This is a statistic that indicates how much network traf
fi
c has been transmitted by the UbiquiSTAT
™
.
Shown are both the number of messages and the total number of bytes. This number should be increase whenever
the thermostat is monitored or programed via the network (Gateway and/or Ubiquity
TM
).
-
Last Traf
fi
c
: This shows the time stamp of the last time network traf
fi
c was received by the UbiquiSTAT
™
.
-
Clear
: This button clears the network traf
fi
c statistics. This includes: Rx Traf
fi
c, Tx Traf
fi
c, and Last Traf
fi
c.
• Other
:
-
USB Activity
: This indicator light is lit whenever there is traf
fi
c detected on the USB port.
-
Network Override
: This indicator light is lit whenever any of the BACnet objects are being commanded remotely
from the network. This occurs, for example, whenever a sub system is implemented for the network through
Ubiquity
TM
. The internal BACnet explorer screen can be used to determine precisely which BACnet object(s) is/are
being externally commanded
(see section 4.5.2.6)
.

SERVICE STATUS
Service Status is defined as a state of the controller or HVAC equipment that requires action by the end user to resolve.
When a service status is active, a red badge is visible on the top of the home screen to the right of the TCS logo.
Touching this badge presents the service status viewer, which shows all active service statuses and when they were
detected. The UbiquiSTAT
™
may be configured to report the following service conditions:
Fan Proving Failure
: When a DI is configured for Fan Proving, the system will shut down if the fan is not detected as
operational after a call from the controller. More information on this feature can be found in
section 5
. The fan
proving status can be reset from the service status screen, thereby re-enabling system control.
Check Filter
: When a DI is configured for Check Filter, service status will indicate the need to replace the air filter.
The Check Filter status is present whenever the DI is active, and is absent when the DI is inactive. This status is
automatically cleared when the filter is changed and the status becomes inactive.
Discharge High
: When the discharge temperature exceeds the high limit value, the heat control is shut down until the
condition no longer exists.
Discharge Low
: When the discharge temperature drops below the low limit value, the cool control is shut down until
the condition no longer exists.
DI1 - DI3
: When a DI is configured for reporting service status, it indicates when the DI is active. A text message can
be customized for each DI.
