Honeywell RLV450 - Manuel (Page 3)

RLV450 69-2201EF-03 2009-08-04 3/4
The schedule consists of 4 periods per day which represents a typi-
cal weekday. You can program the thermostat to skip the periods that
do not apply to your situation. For example, you can skip periods 2
and 3 for the weekend.
The Comfort ( ) temperature is used in periods 1 and 3 and the
Economy ( ) temperature is used in periods 2 and 4. For example,
when the period changes from 1 to 2, the setpoint automatically
changes from Comfort setting ( ) to Economy setting ( ).
You can have a different program for each day of the week; i.e., each
period can start at different time for each day of the week. The
thermostat has been programmed with the following schedule.
To modify the schedule:
n Press Pgm to access the programming mode. Period 1 is
selected.
o Press Day to select the day to program (hold for 3 seconds to
select the entire week).
p
Press Hour and Min to set the start time of the selected period,
or press Clear if you want to skip the period (--:-- is displayed).
q
Press Pgm to select another period, or press Day to select
another day. Then repeat step 3.
r Press Mode to exit the programming mode.
NOTE: If no button is pressed for 60 seconds, the thermostat will
automatically exit the programming mode.
During a power outage, LP (Low Power) appears for the first two min-
utes. Then the screen becomes blank. The settings are stored in
memory. However, if the power failure exceeds 4 hours, the thermo-
stat’s clock must be re-adjusted and, if you are using the automatic
Daylight Savings Time changeover function, it must be re-enabled.
When power returns, the thermostat will return to the mode of opera-
tion active prior to the power failure.
