Installing the thermostat
1. Install the base onto an elec-
trical box.
2. Place the FAN switch as fol-
lows:
3. Place at Yes if you have a
fan-forced heater (to pre-
vent premature burnout of
the motor).
4. Leave at No for better tem-
perature regulation if you do
not have a fan-forced heater.
FAN switch
If you change the FAN switch position after
you have already applied power to the thermo-
stat, disconnect power to the thermostat at the
electrical panel for 3 seconds. The thermostat
will use the new setting when you reapply
power.

Default schedule
When placed in Automatic mode (see page 9), the thermostat follows the programmed
schedule. By default, the thermostat is programmed with the following schedule:
The schedule consists of 4 periods per day, which represents a typical work day. However,
you can program the thermostat to skip (cancel) the periods that do not apply to your sit-
uation. For example, Leave and Return periods are skipped for the weekend in the default
schedule. You can choose a different program every day; i.e., each period can have a dif-
ferent starting time and a different temperature every day.
Monday to Friday
(Mo, Tu, We, Th & Fr) Saturday and Sunday (Sa & Su)

Modifying the schedule
To modify the schedule, proceed as follows:
To skip a period: When the hour or the temperature of the period is flashing, press the Up
and Down buttons at the same time. (Alternatively, set its hour between 23:00 [11:00
PM] and 0:00 [midnight] or its temperature below 5°C [41°F].) Its time and temperature
display will be replaced by dashes (-).
NOTE:
If you do not press any button for one minute, the thermostat will automatically
save any changes you have made and will
return to its normal display .

Set the temperature you wish to use when the thermostat is in Away mode
(see page 11).
2Daylight Saving Time
When the Daylight Saving Time function is enabled (On), the thermostat
automatically switches to Daylight Saving Time on the second Sunday of
March and to normal time on the first Sunday of November.
3Early Start
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
periods; thus there is a delay before you reach the desired temperature.
