EcoNet Smart Thermostat User Guide
The EcoNet®Smart Thermostat is an easy-to-use programmable thermostat that provides complete control over
your home’s smart air and water comfort systems. It’s smart enough to alert you when an issue is detected, yet
it’s designed to be simple to operate with an intuitive touchscreen interface. And it has built-in WiFi so you can
monitor your system and adjust temperatures and schedules while on-the-go.
More than a thermostat, it’s part of an intuitive system that maximizes comfort and efficiency while offering
complete peace of mind—so you can stay focused on what matters most.

Standby Screen
If the thermostat has not been touched for 30 seconds, the screen dims and the standby screen activates
displaying indoor temperature and outdoor weather conditions. If an alert or alarm is present, the alert / alarm
icon will be displayed as well.
The motion sensor* will automatically wake the thermostat and activate the home screen as you approach.
*Motion Sensor may not be available on all units.
The standby screen can be turned off by disabling the back-light under basic
settings (Menu > Settings > Basic)

System Modes
The EcoNet Smart Thermostat will call for heat or cool based on the current settings and temperature. Cooling
and heating equipment may have a delay period before operation is enabled. The delay can be up to 5 minutes
(if the mode was changed right after equipment turns off). Status screen will show a “Hold-Off Timer” for
Equipment State.
Select the mode icon in the bottom right corner of the home screen to quickly
change the operating mode.
Select from Auto, Heat, Cool, E-Heat, Fan and Off
Auto – Activates the heating or cooling system as required to keep your home
within the configured range of set point temperatures. Select the desired
set point, and then use the large adjustment buttons to set the desired
temperature. To adjust your cooling set point, tap the set point on the right -
it will turn blue, then adjust using the plus and minus buttons. The current
temperature in the center of the screen will temporarily be replaced by the
set point in large font during temperature adjustments.
Note: The default deadband or separation between the heating and cooling set points is 2 degrees.
Heat – Turns on heating when the current temperature drops below your set
point temperature. When there is an active call for heating, the words ‘Heating
To’ will appear above the heating set point.

System Modes (con’t)
Cool – Turns on cooling when the current temperature rises above your set
point temperature. When there is an active call for cooling, the words ‘Cooling
To’ will appear above the cooling set point.
(Cooling set point screen)
E-Heat (Heat Pump Systems Only) – The emergency heat option is a manual
setting, not an automatic function initiated by the heat pump thermostat. The
purpose of the emergency heat setting is to bring the backup heat source
online immediately to deliver 100% of the home’s heating demand while
simultaneously locking out the heat pump.
Fan Only – While in Fan Only mode, the heating/cooling equipment is turned
off. Use the plus or minus adjustment buttons to navigate between fan
speeds from Low to High. Press Mode again to reactivate a heating or cooling
mode. Fan only is a manual override of a set schedule. If a schedule is being
followed, the fan speed will return to the scheduled fan speed when you
reactivate the heating/cooling equipment. You can set continuous fan when in
Heating, Cooling or Auto mode from the Settings screen.

Connecting to WiFi
Your EcoNet Smart Thermostat supports WiFi 802.11 b/g/n. WiFi is normally configured during initial setup. You
may, however, be required to reconfigure the settings if your WiFi network settings change.
Connecting to WiFi will enable you to view the local weather and allow you to remotely manage your comfort and
receive critical alarms should something ever go wrong. To save time, we recommend having your home WiFi
network password and your Internet-connected smartphone or tablet close to the thermostat before you begin.
1. Download the EcoNet App and ensure your smartphone or tablet is already connected to your home
WiFi network.
2. Select ‘Create Account’ and follow the instructions.
3. On the EcoNet Smart Thermostat, tap the WiFi icon in the top right corner of the home screen (See Fig. 1).
4. Select ‘Get Started’ (See Fig. 2).
5. When ‘Ready to Connect’ appears, use the EcoNet App to complete the setup process (See Fig. 3).
6. Follow the in-app instructions to complete your connection.
7. You may be required to enter your network password.
8. Tap ‘Done’ to complete setup (See Fig. 4).
