you do not show up, the temperature returns to the
economy level until next weekend.

The economy mode has two periods which should be set as follows:

Period Temperature Setting Start Time Setting

Set to a comfortable

1

level.

Set to an economy

2

level.

Set a time where the temperature
starts to rise to reach a comforta­ble level by the time you arrive.

Set a time where the temperature
starts to drop to an economy level
if you do not show up.

The economy mode should be used as follows:

 Place the thermostat in economy mode during your absence.
 When you arrive, place the thermostat in automatic mode or in

manual mode before the temperature drops back to the
economy level.

 When you leave, switch the thermostat back to economy mode.

During a power outage, the thermostat display remains lit for
approximately the first 15 minutes during which the LP (low power)
indicator appears. The settings are saved in memory. However, if the
power failure exceeds 5 hours, only the thermostat’s clock must be
re-adjusted. When power returns, the thermostat returns to the mode
of operation preceding the power outage.
