Power Outages In the event of a power failure, the thermostat will retain information for proper operation of the heating and cooling equipment as well as maintaining the time. It will not display information on the display screen during the power outage. Once power is restored, the thermostat will resume operation maintaining all previously stored settings.
Page 25 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 27 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 When the thermostat exits the Utility 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 30 INSTALLATION AND MAINTENANCE The thermostat must be in the Normal Operating Mode in order to access to the configuration settings required for the installation and maintenance. Mounting the Thermostat Install the thermostat at 5 feet (1.5m) above the floor in an area with good air circulation at average temperature.
