Analog Outputs (Ao); On Screen Quick Start Wizard - TCS UbiquiSTAT US4010 Product Manual

INITIAL SETUP

3.6 Analog Outputs (AO)

There are up to two analog outputs (depending on model), AO1 and AO2. Both may be configured in programming as
0-20mA or 4-20mA and direct or reverse acting. These settings are available via the touchscreen under Settings>Ad-
vanced>Analog Outputs.
• Direct Acting: The analog output increases as the input increases.
• Reverse Acting: The analog output decreases as the input increases.
• Output Range: Selectable as 0-20mA or 4-20mA.
The output can be converted to 0-10V or 2-10V by connecting the included 500 Ohm resistor between AO and
Ground terminal.
The factory defaults are direct acting and 4-20mA. Analog outputs can be configured for:
• Heat: If set for heating, the analog output operates when the room temperature is at or below the heating setpoint, where
4mA is maximum heat (valve open) and 20mA is minimum heat (value is closed), by default.
• Cool: If set for cooling, the analog output operates when the room temperature is at or above the cooling setpoint, where
4mA is minimum cooling (valve closed), and 20mA is maximum cooling (value is open), by default.
• Economizer: The analog output operates when the mixed or discharge temperature is at or above 55°F by
default, where 4mA is minimum cooling (damper is closed), and 20mA is maximum cooling (damper is open), by default.
By default, the economizer is enabled when the following conditions are met:
• Outdoor air is below 55F (free cooling available).
• Occupancy mode is occupied.
• Call for cooling is needed.
Economizer operation requires an outdoor air and discharge or mixed air input.
The following are additional features that can be programed using the internal BACnet explorer:
• Heat and Cool Aquastat
• Midpoint Control
• Demand Ventilation (CO
2
• Pre-occupancy Purge

3.7 On Screen Quick Start Wizard

When first powering on the UbiquiSTAT (or after a factory reset) a sequence of configuration screens will appear that must
be completed before the thermostat becomes operational. All thermostat control and communication are disabled until
the quick start wizard is complete.
Choose your desired settings for the following pages:
• Display Settings
• Date & Time
• Thermostat Type
• System Mode
• Occupied Fan Mode
• Communication Mode: TCSbus allows the UbiquiSTAT to reside on a network with TCS controllers. TCSbus mode re-
quires a software upgrade of the Ubiquity Site Gateway.
- US4100: TCSbus, BACnet MS/TP, BACnet/IP, None
- US4000: TCSbus, BACnet MS/TP, None
• Network Address: This must be unique for each controller on the RS-485 network (* Not shown if BACnet/IP was select-
ed). The valid address range is from 1-127. If an address of value 0 is desired this can be entered after the initial setup.
