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 or cooling system to change the tem-

perature so that the desired temperature is

reached at the beginning of the next pro-

gram 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 ac-

tivate 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 dis-

play shows the temperature you want. The

thermostat will override current program-

ming and keep the room temperature at the

selected temperature for two hours. After

two hours, the thermostat will automatically

revert to the program.
