ing and cooling setpoints.
4.5.2 Advanced Settings
4.5.2.1 Analog Output
For more information on analog outputs, see
. The first screen provides a summary of the current configuration
for each of the two analog outputs and an entry point to the programming screens. On the programming screen, text on
the right side describes how the current configuration behaves at either end of the output range.
The programming screen offers limited programing options in order to allow for quick and simple initial setup. Use the
internal BACnet explorer to perform full configuration.
Mode
:
Off: No control is performed. Analog output is fixed at 0%. The actual output in milliamps depends on action and range
settings below.
Heat
:
The analog output operates at or below the heating setpoint to modulate heating equipment.
Cool
:
The analog output operates at or above the cooling setpoint to modulate cooling equipment.
Economizer
:
The analog output operates at or above the economizer setpoint to modulate an outdoor air
damper. The economizer is enabled using the dry bulb setpoint mode.
Action
:
Direct Acting: The analog output increases as the input increases.
Reverse Acting: The analog output decreases as the input increases.
Range: Selectable as 0-20mA or 4-20mA.
4.5.2.2 Temperature Calibration
The UbiquiSTAT has four temperature inputs: three RTD inputs (T1, T2, T3), and an internal digital temperature sensor.
These inputs are factory calibrated. However, an installation may have inherent measurement inaccuracies from sources
such as sensor lead resistance and sensor placement. Therefore, a field calibration may be required. Factory calibration is
permanently stored in the thermostat and is not affected by field calibration. The calibration is a simple offset applied to
the raw temperature reading.
When preforming this calibration, use the up and down arrows to match the temperature reading on the screen to the ref-
erence temperature (Settings > Advanced > Temp Calibration). The calibrated reading, as well as the original reading, and
calibration offset, are displayed on the screen and are adjusted by increments of 0.1 degree Fahrenheit or Celsius.
4.5.2.3 Room Temp Source
Room temperature is used for all of the UbiquiSTAT temperature control logic. Select the temperature source: internal,
remote, or average of internal and remote. The temperature source buttons each display a live reading corresponding to
their source. When the averaging method is chosen, the averaging controls become visible. Use the up and down arrows
to set the averaging ratio as desired. Each touch of the up and down arrows changes the value by 5%. See
for
more information.
4.5.2.4 Network Settings
•
RS-485
-
Baud Rate
: All controllers on the network must use the same baud rate.
-
Mode
: All controllers on the network must use the same protocol. Mixing BACnet, ModBus, or other protocols on the
same network is not allowed. TCSbus must be used when the UbiquiSTAT is used on an existing TCS network.
-
Address
: All controllers on the network must have a unique address.
-
Device Instance Number (BACnet MS/TP Only): This number must be unique across the entire BACnet network. The
default value is a combination of the TCS BACnet vendor Id (496) and the previously entered network address. This is
