•
Only properties that are part of the controller programming (stored in non-volatile memory) are editable. This excludes
any objects that are commandable (or may overridden) via the network.
•
Text strings are not editable, therefore character string value (CSV) objects may not be changed.
for a list of all BACnet objects.
While the object list in each model may vary due to feature being added or removed, the order of objects as shown
by the index number in the explorer is maintained and follows the order of the objects as listed in the BACnet
Explorer Guide. The BACnet Explorer Guide is a complete object list covering all models.
4.5.2.7 Factory Defaults
Selecting this menu item will cause the UbiquiSTAT to change all settings to their factory default values. The UbiquiSTAT
will then restart and display the quick start wizard. For example, this feature may be used when re-purposing a thermostat.
All previous programing will be lost!
4.5.2.8 System Event Log
The system event log contains entries for the last 100 events. An event can be one of three classes: info, action, and fault.
Events contain a timestamp, description, and possibly an internal programming code (meaningful only to TCS technical
support). Additional information is displayed for certain events as available.
•
Info
: Describes events in the system for informational purposes only. An example is service status history which records
any service status activity including duration.
•
Action: Describe changes made to the device from a local user or an outside programming source (i.e. Ubiquity Cloud).
•
Fault: These are only reported by the firmware when an unexpected behavior is detected in the code. Report any faults to
TCS technical support.
4.5.2.9 Display
The display setting screen consist of:
•
Temperature Units
: Fahrenheit / Celsius.
This setting only effects how temperature values are displayed on the screen. This does not affect the values
visible through RS-485 communication. All values on the RS-485 port are in units of Fahrenheit.
•
Time Format
: 24 hour / 12 hour.
•
Backlight Brightness
: Low / Medium / High.
When using the “Low” setting for the “Display Brightness”, the display will go completely dark after 10 minutes of inactivi-
ty. Note: Prior to UbiquiSTAT version 1.01.1, the Low setting will dim the display, but it will not go completely dark.
4.5.2.10 System Test Mode
When installing or servicing a controller or HVAC system, it is often necessary to test out the connections and basic setup.
This requires forcing the controller to activate its various outputs to prove that the system has been installed correctly.
The system test mode facilitates this by providing a simple test interface.
When entering the system test mode, all internal control logic is disabled and the outputs are all set to their inactive (re
-
lays) or 0% (analog outputs) state. Control is resumed when the system test mode is exited, or after 10 minutes of inactiv
-
ity.
WARNING:
There is no equipment protection in this mode. Damage may occur if proper and safe sequencing is not followed.
