Z-Wave™ Thermostat

The Z-Wave™ thermostat provides for typical thermostat control of a central heating and cooling HVAC system plus has the added feature of Z-Wave™ communications for remote control.

The thermostat has a large, backlit graphical display, control buttons, status LEDs and a temperature sensor. The thermostat can display multiple screens for different functions of the thermostat. In the default thermostat control screen, shown below, it displays the current temperature, setpoint, system mode, manual fan mode, time, outside temperature and other information.

Display operation

Thermostat control screen

Normally the thermostat displays the thermostat control screen as shown above. Using the Menu button, you can access other screens and functions of the thermostat.

Minimized Display Mode

Optionally, you can set the thermostat to show only the temperature in a minimized display mode.

This mode can be set on or off in the thermostat Users Settings screen if enabled. (See page 16 for more information)

Other screens

Other standard screens are selected by the Menu button and include: Schedules, User Settings, Usage Graph, ESM Setpoints and Thermostat Info. Other screens, such as the Schedules screen, may be present and selectable from the

menu button depending on options included or selected in the installation setup process.

Backlight

The thermostat has a backlit display for low light and night visibility. It can be set to remain on constantly, or to turn off after a 20-45 second delay. These are selectable in the User Settings menu.

Z-Wave™ Operation and Programming

Z-Wave™ controllers from various manufacturers may support the Z-Wave™ Thermostat General V2 Device class used by the Trane Z-Wave™ Thermostat. The following procedure will allow the thermostat to be added to a Z-Wave™ network.

If you are using a controller that is not a Schlage bridge, consult the instructions that came with the controller to ﬁnd out how to enroll a new device.

Inclusion

Hold the bridge within 6 feet (1.8 meters) of the thermostat throughout all of step 2.a.

Note: After you begin the enrollment process, you have 30 seconds to complete the remainder of the steps. Study the steps below before beginning.

Press and release the plus (+) button on the bridge.b.

Press the c. MENU button on the thermostat.

Scroll down to d. Z-Wave Install, and press the Select button.

Press the e. Yes button to enroll the thermostat.

Observe the lights on the bridge. The orange light will blink while enrollment is taking place. Enrollment is f. complete when the orange light becomes solid.

Exclusion

Hold the bridge within 6 feet (1.8 meters) of the thermostat throughout all of step 2.a.

Note: After you begin the enrollment process, you have 30 seconds to complete the remainder of the steps. Study the steps below before beginning.

Press and release the minus (-) button on the bridge.b.

Press the c. MENU button on the thermostat.

Scroll down to d. Z-Wave Install, and press the Select button.

Press the e. Yes button to exclude the thermostat.

Observe the lights on the bridge. The orange light will blink while exclusion is taking place. Exclusion is f. complete when the orange light becomes solid.

Inclusion and Exclusion

Inclusion or exclusion is started by putting the controller into add node or remove node state and performing the procedure outlined above. As part of the process, the thermostat sends a node information frame at normal power. Low power inclusion or low power exclusion is not possible.

Operation

Thermostat Control Buttons

The Thermostats buttons are “Soft Keys” meaning that they change functions when you change screens. The function of the button is deﬁned by “on-screen labels” that are dynamic and change when you change screens.

LEDs

The Thermostat has four LED’s that displays status information. The LEDs have dynamic “on-screen” labels that can change with the screen being displayed.

Thermostat Screens

A unique feature of the Thermostat graphical display is the ability to have multiple display screens. In addition to a main thermostat control screen, menus and other control screens for special functions are provided. This makes an intuitive and easy to use “user interface”. It allows the many functions of the Thermostat to be easily navigated.

The main screen is the Thermostat Control Screen. From this screen you can access a menu screen that will list other control screens or setup screens.

Thermostat Control Screen

This is the thermostats default screen and the only screen needed for basic thermostat operation (temperature setting and heat/cool mode selection). All other screens will automatically timeout and return this screen after 120 seconds of no activity.

Minimized Thermostat Screen

(This feature is disabled by default. See page 16, Screen Timeout for more information)

The main thermostat screen will go to a “minimized” screen after a 30 second timeout period. This presents a simple uncluttered display of the current room temperature.

Menu Selection Screen

Pressing the Menu button on the Thermostat Control Screen will go to the Menu Selection screen. This screen presents a list of the other functions or setup screens that can be selected.

Schedules Screen

(Optional screen) Only shows up in the Menu Selection list if local scheduling is enabled. (See Installer Settings, then System Settings Menu and then Schedule Enable on page 23).

This screen is used to view and edit the time based setback schedules for the thermostat.

Thermostat User Guide

User Settings Screen

This screen is a submenu of user settings for the initial setup of the thermostat. You can set the clock, minimized screen timeout, Fahrenheit or Centigrade selection, sensor calibration and display settings.

Usage Graph

Shows daily heating and cooling runtime hours for a week.

ESM Setpoints

This screen is a submenu of the Energy Savings Mode settings. You can set the heating and cooling setpoint setback temperatures. These settings are used when the thermostat is in the ESM mode.

ZWave Install

This screen is a submenu for installing the thermostat into a Z-Wave network. When the Z-Wave network controller is ready to install the thermostat, press the YES button to install.

Thermostat Info Screen

This is a quick reference list of the thermostat ﬁrmware versions, Z-Wave network addresses and HVAC system setup.

The main Thermostat Control Screen is the default display screen and is the screen that is normally displayed on the Thermostat.

Temperature Display

The Thermostat will display the current temperature from the internal temperature sensor.

Setpoint Display

The heating and cooling setpoints are displayed next to the Setpoint Up/Down buttons. In the HEAT mode, the Up/Down buttons change the heat setpoint. In the COOL mode, they change the cooling setpoint. When in AUTO mode, the buttons change the last call’s heating or cooling setpoint. Note that the setpoints will “push” each other if they are adjusted to get within the minimum Heat/Cool separation setting. This is normally 3 degrees.

Clock Display

The current time is displayed in the upper left corner of the main screen. Set the clock from the User Settings Menu.

The time will blink when the clock has not been set.

Thermostat Control Screen Buttons

Setpoint Up and Down Buttons

Pressing the Up or Down button in the main Thermostat Control Screen will take you to the Heating Setpoint or Cooling Setpoint screen, as shown below.

The UP and DOWN buttons adjust the setpoint temperature. Pressing the UP button will increment the setpoint value by one degree and conversely, pressing the Down button will decrement the setpoint one degree. Pressing and holding a button down will cause the setpoint to continuously change until the button is released.

Setpoint Range: The setpoints can be set from 55°F to 90°F (12°C to 32°C) for Heating or 60°F to 99°F (15°C to 37°C) for Cooling.

Setpoint Push: Note that you cannot lower the cooling setpoint below the heating setpoint. The thermostat will push the heating setpoint lower if you try to lower the cooling below the heating setpoint. It maintains a 3 degree separation between the heating and cooling setpoint. The same is true for raising the heating setpoint above the cooling setpoint. Again the thermostat will “push” the cooling setpoint up to maintain the 3 degree separation.

NOTE: If the system mode is OFF, pressing the setpoint Up or Down buttons will take you to the system mode screen. You must set the mode to an operating mode before you can change the setpoints.

To change the Heat Setpoint you must be in Heat mode, to change the Cool Setpoint you must be in the Cool mode.

If you are in Auto mode when you press the Up or Down buttons, you will go to the last call’s mode, heating or cooling, setpoint setting screen.
