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

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.

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.

System Type: Set the mechanical system type to Heat Pump in the Installer Settings Menu
Single Stage Compressor Systems use Y1 for stage 1 heating/cooling, and W1 for stage 2 Aux Heating.
Two Stage Compressor Systems use Y1 for stage 1, Y2 for stage 2 heating/cooling, and W1 for stage 3 Aux Heating.
Change Over Valve: You must configure the thermostat’s changeover valve setting to work correctly with your HVAC
system. Check your system information to be sure.
•

Changeover settings are made in the Installer Settings – System Settings - Mechanical Settings menu.

•

Changeover with cool is the default setting and typical for most systems.

•

If you get cooling when you expect heating, change the C/O type to the opposite setting.

HVAC system transformer: Heat pump systems have one system transformer. Do not cut the RC/RH jumper. Wire the
HVAC systems 24VAC common (blue wire) to the 24Com terminal, and the 24VAC return (red wire) to the 24RC terminal.

HVAC System Operation and Setup
General Heating and Cooling Operation

In the HEATING mode, the heating system will be turned on at one degree below the setpoint and will turn off at the
setpoint. This turn on and turn off offset is referred to as the heating setpoint “delta T” and is adjustable in the Installer
Settings menu of the THERMOSTAT. It is set to the one degree operation by default.
In the COOLING mode, the cooling system will be turned on at one degree above the setpoint and will turn off at the
setpoint. Similarly, the cooling setpoint delta T is adjustable in the Installer Settings menu.
In the AUTO mode, the system will switch between heating and cooling as determined by the heating and cooling
setpoints and the current temperature. Once in a heating or cooling mode of operation, the normal one degree setpoint
control is maintained.
Setpoint Push. Heating and cooling setpoints are forced to maintain a separation between them, with a default setting
of 3 degrees. If the heating or cooling setpoint is changed to be within the setpoint delta, the system will automatically
“push” the other setpoint to maintain the setpoint delta separation. The H/C setpoint delta is also adjustable in the Installer
Settings menu of the THERMOSTAT.

Standard HVAC System Types

Gas or electric heating systems are considered “Standard” HVAC systems. These systems consist of an indoor furnace/
blower assembly and an outdoor AC condensing unit (for those systems with air conditioning installed). These systems in
general are referred to as central forced air HVAC systems.
You must configure the Thermostat to match your HVAC system type for correct system operation.

Setup
Standard System Type Selection
To configure the Thermostat for standard Gas/Electric HVAC system operation, change the Type in the Installer Settings –
System Settings – Mechanical Settings menu option to Gas/Elec.

Fan Type Selection
Gas systems typically do not require a fan output for heating operation. Set the Fan Type in the Installer Settings –
System Settings – Mechanical Settings – Fan Type to GAS.
Electric (and hydronic) heating systems typically do require a fan output with the call for heating. Set the Fan Type in the
Installer Settings – System Settings – Mechanical Settings – Fan Type to ELEC.
Be sure to check your HVAC system’s requirements.

Heat Pump HVAC System Types

Heat Pump HVAC systems are combined heating and cooling systems. The system consists of an indoor “air handler” (a
blower fan and coil assembly) and an outdoor unit. Heat pumps change from heating mode to cooling mode by switching
the refrigerant flow using a “changeover” or “reversing valve”. In both heating and cooling operation the compressor and
fan outputs are on and the state of the changeover output determines if heating or cooling is being provided. Heat pumps
can have one or two stages of compressor operation plus an optional third stage of electric heat strips.
31

Thermostat User Guide
The third stage of heating will be turned on when the current temperature falls 3 deg below the current setpoint and will
turn off at the setpoint.

Setup
Heat Pump System Type Selection
To set the Thermostat for Heat Pump HVAC operation, change the Type in the Installer Settings – System Settings –
Mechanical Settings menu option to Heatpump.

Changeover Type Selection
Most heat pump systems are designed to work normally in the heating mode and require a change over output for cooling
output. Change the C/O Type in the Installer Settings – System Settings – Mechanical Settings menu option to match your
system needs.
Changeover with Cooling: Set C/O Type to w/Cool (This is the default setting).
Changeover with Heating: Set C/O Type to w/Heat.
Note: During Heat Pump operation the changeover relay, once engaged, will stay on until the opposite HVAC call
occurs.
Check your HVAC system requirements for correct settings.

Minimum Run Time (MRT)
The thermostat has a Minimum Run Time after the start of any heat or cool call. This minimum run time assures even
heating and cooling cycles. Minimum Run Time will keep the system on even if you change the setpoint to a temperature
that would satisfy the call, until the MRT expires. Changing the Mode to OFF will cancel the MRT and the system will turn
off immediately. MRT can be adjusted in the Installer Settings Menu of the THERMOSTAT.

Minimum Off Time (MOT)
The thermostat has a Minimum Off Time after any heat or cool call. This delay prevents rapid heating/cooling cycles and
also provides “short cycle protection” for compressor calls. This delay may be noticeable when you change a setpoint and
it does not respond immediately due to another call that has recently completed and the MOT delay timer is preventing the
restart of the system. The MOT delay time can be adjusted in the Installer Settings Menu of the THERMOSTAT. There is
a minimum of 5 minutes delay to assure compressor protection.
Note: “WAIT” will be displayed on the thermostat screen while the minimum equipment off time is being enforced.

Installation
Power

The thermostat requires 24VAC power from the HVAC system it is controlling. Connect the 24VAC Common (typically
the Blue wire/terminal) and 24VAC R (typically the Red wire/terminal) from the HVAC system to the thermostats HVAC
System terminal block 24VCom and 24V RH or 24V RC terminals (the RH and RC terminals are default tied together)

Common or Split Transformer Systems
Most HVAC systems have a common heating and cooling transformer. A jumper wire is connected to tie the RH and RC
inputs together for this configuration. If you have a system with separate heating and cooling transformers, you will need
to separate the RH and RC inputs by cutting the jumper on the PCB.
When wiring split systems, wire the heating systems 24VAC R (red wire) to the thermostat’s RH terminal, and wire the
cooling systems 24VAC R to the thermostat’s RC terminal. Also wire the cooling systems 24VAC Com to the thermostat’s
24VAC Com terminals.
Note: Do not split RC/RH for Heat Pump systems!
