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 tech
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
TM
).
Fault
: These are only reported by the firmware when an unexpected behavior is detected in the code. Please report
any faults to TCS tech 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.
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
(relays) or 0% (analog outputs) state. Control is resumed when the system test mode is exited, or after 10 minutes of
inactivity.
WARNING:
There is no equipment protection in this mode. Damage may happen if proper and safe sequencing is not fol-
lowed.
