OPERATING FEATURES
Now that you are familiar with the thermostat
display and buttons, read the following informa-
tion to learn about the many features of the
thermostat.
• COMPUTED ENERGY MANAGEMENT
RECOVERY (EMR) — The thermostat’s
microcomputer can be set to automatically
calculate the time it will take to change the
temperature to the next program setting.
Then the thermostat will activate the heat-
ing system to change the temperature so
that the desired temperature is reached at
the beginning of the next program period.
As an example of this feature, assume that
you have programmed your thermostat to
provide an overnight heating temperature of
62
°
F, and that during the next program
period, beginning at 6:00 AM, you have
programmed a temperature of 70
°
F. The
thermostat will automatically activate the
heating system at about 5:00 AM, so that
the programmed 70
°
F temperature is
reached by about 6:00 AM.
The thermostat is configured at the factory
so that this feature is disabled. If you wish
to have this feature, refer to the installation
instructions for this thermostat, or contact
your local heating/cooling contractor.
• TWO HOUR TEMPERATURE OVER-
RIDE — Press or until the
display shows the temperature you want.
The thermostat will override current pro-
gramming and keep the room temperature
at the selected temperature for two hours.
After two hours, the thermostat will auto-
matically revert to the program.
