Smart Stat Navigation and Indicators

| Home Screen Layout

On the upper left corner of the Local Interface Sensor screen you will find the signal bars for the 900 MHz mesh network.
If signal bars are white the Smart Stat is paired to Central Control Unit and communicates over a 900 MHz mesh network.
If signal bars are dark grey the Smart Stat is not paired to a CCU.
To the right of the signal bars you will find the fan icon. Which indicates a fan called on the connected equipment.
To the right of the fan icon is the operation mode icon which is represented by a snowflake for cooling mode or a flame for heating mode.
Below the three previously mentioned icons the current space temp and humidity are displayed.
On the front cover of the Smart Stat lower left corner you will find the orange fan mode override button. This button has four functions noted below.

Fan Off / System Off

The fan runs during conditioning only

Fan low runs during occupied

Fan high runs during occupied

If the Smart Stat zone has a schedule and the fan is ON. You will see Changes to unoccupied at x: xx. (Ex. x: xx meaning scheduled off time of the zone)
At the noon position below the transparent ring you will find the temperature/humidity sensor.
On the front cover of the Smart Stat lower right you will find the occupancy sensor. The sensor can be turned ON or OFF depending on the installed location of the Smart Stat and application.

| Touchpad Layout

On the Local Interface Sensor middle cover, there is a transparent ring that is touch sensitive with 14 segmented indicator LEDs. For this document, we will use a clock as a reference for the touchpad points.

The 5 or 7 o’clock position = Down

The 9 o’clock position = Left

The 12 o’clock position = Up

The 3 o’clock position = Right

| Input Screen

Using a paper clip or piece of solid 16-gauge wire bent at a ninety-degree angle press the recessed mode button in the upper left corner of the Local Interface Sensor.
The first item on the menu screen shows Inputs connected to the Smart Stat.
Press the down (5 or 7 o’clock) buttons to scroll through the list of inputs on the menu. Inputs on the list will show a value only if the input is connected to the Smart Stat. (Example: Analog 1, Analog 2, Thermistor 1, Thermistor 2, etc.)
Along with the standard inputs there are some unique inputs specific to the Smart Stat. (Example: Light, UVI, C02, C02 EQ, VOC, and Sound.)

| Outputs Screen

Pressing the right (3 o'clock) button or once from the menu screen takes you to the outputs menu.
On the outputs menu you can find the outputs for two cooling stages, one fan stage, two heating stages, and a reversing/three-way valve output if used with a heat pump.
Press the down button to scroll through the list of outputs on the menu. The list will show an ON/OFF command next to each output. (Example: O/B -> ON/OFF etc.)
In addition selected outputs can be turned ON/OFF for testing or troubleshooting purposes.

| Performing Output Test

Selected outputs can be tested using the following steps.
From the outputs menu press the down button to select the desired output.
Press the right button and note the status of the output. Press the up and down buttons to toggle the output ON/OFF.
After testing the return output to its default setting, press the left (9 o’clock) button twice to return to the menu.

| Smart Stat Information Screen

Pressing the right (3 o'clock) button twice from the menu screen takes you to the Smart Stat Information Screen.
The information found on this screen is view only and displays information about the Smart Stat such as the connected Room, Zone or Equip name, the Pairing Address of the Smart Stat to CCU, Firmware Version, Bootloader Version, and the Serial Number of the Smart Stat.
The support team may need information from this screen for troubleshooting purposes.

| Installer Options Screen

Pressing the right (3 o'clock) button three times from the menu screen takes you to the Installer Options Screen.
On the installer screen menu, you will find a menu item paired with CCU which will be selected when pairing the Smart Stat to CCU during installation.
other menu items are used for troubleshooting such as:

Temp Offset (Used to calibrate onboard temp sensor), Hardware Test (Used to check and test functions of the Smart Stat), BLE Debug, and Factory Reset (which will restore the Smart Stat to the default configuration.

Enable Temp Slave - this will enable the Local Interface Sensor to function as a sensor. This would be for connecting a Local Interface Sensor to a Smart Node for VAV/DAB.

Enable Lighting Slave - this will enable the Local Interface Sensor to function as a daylight harvesting sensor. This would be for connecting a Local Interface Sensor to a Smart Node for lighting.
