Lux Products P621Ia Thermostat User Manual


 
By default, this thermostat has 4 separate program periods for both Heat and
Cool mode, they are: MORN, DAY, EVE, and NITE. Each period ends at the start
time of the following period. The heat programs are set in HEAT mode, and the
cool programs are set in COOL mode.
NOTE: If the thermostat is configured to use only 2 periods per day instead of 4
(SYSTEM CONFIGURATION AND SETUP OPTIONS), the thermostat will only use the
DAY and NITE periods. The MORN and EVE periods will not be visible on the
screen.
SET TEMPERATURE PROGRAMS: Move the Set Slide switch to the TEMP PROG
position. Programming will start with all 5 weekdays, Monday through Friday (all
grouped together). Use the UP/DOWN buttons to adjust the start time for the
MORN period, then press the NEXT button to advance. Use the UP/DOWN buttons
to adjust the set temperature for the MORN period, then press the NEXT button to
advance. Now adjust the start time and set temperature for the DAY period,
pressing the NEXT button after each to advance. Continue with these same steps
to adjust the start times and set temperatures for the EVE and NITE program
periods.
