Away temperature
2
Set the temperature you wish to use when the thermostat is in Away mode
(see page 6).
Daylight Saving Time
3
When the Daylight Saving Time function is enabled (On), the thermostat au-
tomatically switches to Daylight Saving Time on the second Sunday of March
and to normal time on the first Sunday of November.
Year, Month, Day
4
These parameters are available only if the Daylight Saving Time function is
enabled (On).
Early Start
5
Early Start is used in Automatic mode only. When Early Start is enabled (On),
the thermostat determines when to start heating so the desired temperature
is attained at the beginning of Wake and Return periods. When Early Start is
disabled (Off), heating starts only at the beginning of Wake and Return peri-
ods; thus there is a delay before you reach the desired temperature.
Keypad lock
6
The settings are locked. The temperature adjustment buttons only allow you
to view the temperature setpoint.

Troubleshooting

Your thermostat requires little or no attention. Most problems can generally
be traced to the following:
Problem
Thermostat is hot.
Wrong temperature is
displayed.
Wrong time is displayed.
Temperature does not
change according to the
programmed schedule.
LP appears on the
screen or the screen is
blank despite there is no
power outage.
The settings cannot be
changed.
Solution(s)
This condition is normal. Ensure that the heater capacity does not
exceed the thermostat's maximum load.
Correct it if any of the following situations exists:
• The thermostat is exposed to an air draft.
• The thermostat is located near or above a heat source such as a
light dimmer
The thermostat was without power for more than 5 hours.
Check that the thermostat is in Automatic mode.
Check the schedule and clock settings. If the thermostat is
configured in 12-hour format, ensure that PM appears on the screen
when afternoon times are displayed.
The thermal circuit breaker in the heater is opened.
This can happen if the heater is obstructed by furniture or curtain
and has overheated, or if the thermal circuit breaker is defective or
too sensitive.
The settings are locked (see page 7).
