THERMOSTAT CONSERVATION MODE
The Conservation Mode of the thermostat allows either you or your utility to modify scheduled and
HOLD SETPOINTs to reduce energy consumption.
There are two Conservation Modes: User Conserve and Utility Conserve.
These controls are active when in the Conservation Mode:
• CONSERVE Status Light
• CONSERVE Button
• HOME Led
Page
26
User Conserve Mode
You can initiate the User Conserve Mode in your thermostat by pressing the Conserve Button. This
action will turn ON the Conserve Status light Green.
The purpose of the User Conserve Mode is to save energy by incrementing, in the case of Cooling,
or decrementing, in the case of Heating, the scheduled target temperature by a specified fixed
value.
If a temporary HOLD or the current scheduled SETPOINT expires, the incremental temperature
change is applied to the next scheduled SETPOINT.
Note that you will not be able to change any scheduled or HOLD SETPOINTs while you are in the
User Conserve Mode, you will have to exit this mode before you can make those changes.
At this point, the thermostat will set back the current SETPOINT
(HOLD or scheduled SETPOINT) by a fixed value of 1°C to
conserve energy. The SETPOINT’s name at the Home Screen of
the thermostat will be replaced by a label showing “Conserve”.
Page

During the Conserve Mode you will only be able to modify the following parameters:
Language
24 hour Time Format
Change Filter Reminder
Contact Information
Exit from User Conserve Mode
To exit the User Conserve Mode, press the Conserve Button again and the thermostat will go back
to its regular schedule or applicable HOLD. The Green Conserve Status light will turn OFF.
When the thermostat exits the User Conserve Mode, it enters the Normal Operation Mode, w here
the SETPOINTs are as programmed by the Schedule or HOLD and you are able again to modify
any configuration parameter of the thermostat.
Page
28
Utility Conserve Mode
If your utility offers a energy reduction plan and you are enrolled in the program, your utility can
start a Utility Conserve Mode. This allows your utility to send a signal over the communications link
to increment the temperature a few degrees (when using the cooling system) or decrement it a few
degrees (when using the heating system).
If a temporary HOLD or the current scheduled SETPOINT expires, the incremental temperature
change is applied to the next scheduled SETPOINT.
At this point, the thermostat will set back the current SETPOINT
(HOLD or scheduled SETPOINT) by a fixed value of 2°C to
conserve energy. The SETPOINT’s name at the Home Screen of
the thermostat will be replaced by a label showing “Conserve”.
When entering a Utility Conserve Mode, your thermostat will show
the word “UTILITY” under the room temperature and the Conserve
Status Light turns on Amber
Page
29
Note that you will not be able to change any scheduled or HOLD SETPOINTs while you are in the
Utilty Conserve Mode, you will have to exit this mode before you can make those changes.
During the Utility Conserve Mode you will only be able to modify the following parameters:
Language
24 hour Time Format
Change Filter Reminder
Contact Information
Exit from Utility Conserve Mode
The Utility Conserve Mode ends when your utility sends a signal to the thermostat to end the Utility
Conserve Mode, or y ou opt-out of the Utility Conserve Mode by pushing the Conserve Button.
In the case you opt-out of the Utility Conserve Mode, you will not be able to go back to it. The only
Conserve Mode you will be able to enter is the User Conserve Mode
