OPERATION
System Selector Switch
The System Selector Switch on the front of the thermostat determines the
Operating mode of the thermostat. You may select COOL ,OFF ,
HEAT,AUTO. In order to take full advantage of this thermostat’s
feature, we recommend using the AUTO mode. Refer to the Auto
Season Changeover information on Auto Season Changeover..
NOTE: Anytime you install or remove the thermostat form the wallplate, slide the System
Selector to the OFF position to prevent the possibility of a rapid system On-Off.
Fan Switch
The Fan switch should normally be located in the AUTO position.
The Fan will be turned on along with normal operation of your
system. In a normal gas or oil furnace, the Fan will be turned on by
your furnace after its warm-up delay. For electric heat, air conditioning, and heat pump
operation, the Fan will turn on with the system. To run the Fan on continuously, slide the
Fan switch to the ON position.

At the next program change, the Temporary Override, and the next program
temperature becomes the set point temperature. To end the Temporary
Manual Override:

Auto Season Changeover
When the System Selector is in AUTO position , the thermostat will automatically
change between Heating and Cooling systems, depending on your program .We
recommend keeping your programmed heating and cooling temperature at least 4˚F
(2˚C) apart to allow the Auto Season Changeover to occur when the appropriate
temperature span has been reached. However, if your heating and cooling programs set
temperatures are close, there is a built-in program to prevent the thermostat is in
Temporary, a Designated Day Override or Permanent Override , as these overrides are
energy saving settings. Auto Season Changeover will still function in Home Today mode,
as this is a comfort setting.
For example, you may have the following temperatures programmed at a given time:
Heat Set Temp=68˚F Cool Set Temp=78˚F
If the room temperature rises above 78˚F, then the thermostat will automatically change
to cool mode and turn on the air conditioner.
Likewise, the thermostat will automatically change to heart mode and turn
On heat when the room temperature falls below 68˚F.
HOME TODAY
This patent pending feature allows you to quickly and temporarily override your energy
saving program setting on days when you are normally away from home with one key
press.
■ Press to enter the Home Today override .The highest program temperature for
today will be selected from your programs in Heat mode
and become the set temperature.(In Cool mode ,Home
Today will select the lowest program temperature for today
to be the set temperature.)
■ The display will alternate between “HOME” and the current time.
■ When pressed during the day, the thermostat will remain in Home Today mode
until the first program of the next day.
■If the system is changed between Heat and Cool modes (either manually or by
Auto Season Changeover) during the “Home Today” override period, the setpoint
temperature will be automatically update.It will automatically change from the highest
heat program setpoint to the highest heat program setpoint .
■ Press to exit Home Today mode before the schedule ending time. “Home
Today” override period, the setpoint temperature will be automatically updated. It
will automatically change from the lowest cool program setpoint to the highest
heat program setpoint.
■ Press to exit Home Today mode before the schedule ending time.”HOME” is no
longer displayed on the LCD screen, and the thermostat returns to the current
program.
■ You can manually change the setpoint temperature while in Home Today mode.
Refer to the Temporary Manual Override instructions .Manually changing the set
temperature while in Home Today mode will not affect the Home Today ending
time, However, the set temperature will not change automatically with a manual
or Automatic change between heating and cooling.
Energy Monitor
■ The Energy monitor feature measures and stores the
amount of time the heating and air conditioning system
operates. Usage can be display for Today (since 12 am),
Yesterday, This Week (since Monday), Last Week (last
Monday through Sunday), and Total (up to 999 Hrs).By monitoring your energy
usage, you see how much the set-back periods are saving , and you can test
program adjustment to save even more. To review energy usage, press to cycle
through Today, Yesterday, this Week, Last Week, and Total. Press again to return
to normal mode, or wait 15 seconds for the display to return to normal mode .You
can also return to normal mode at any time by pressing RERURN.
■ For example: This LCD display shows Today’s usage to be 10 Hours, 26
minutes.
■ Press and hold for 3 seconds to reset the Energy Monitor’s counters.
The display will blink, and counters will be cleared to zero.
NOTE: Clearing the Energy Monitor counter will also clear the Filter Monitor
counter , as Filter usage and Total Energy usage are the same. Also, clearing the
filter Monitor counter will clear ALL Energy Monitor counters as well.
Filter Monitor
Your thermostat also keeps a record of the number of hours your filter has been in use.
To maximize your system’s performance and energy
efficiency, change or clear your filter regularly.

Backlighting
Your thermostat has an electroluminescent lamp that backlights the display for easy
viewing in the dark.
When any key is pressed the display is illuminated.
The display will remain illuminated for 8 seconds after the last key is pressed. This
allows the light to stay on if you need to operate several keys.
Note: If the thermostat is in Low Battery warning condition, the backlight will not operate.
Replace with 2 new AA alkaline batteries to restore the Backlight function.
Low Battery Warning
Your thermostat has a two-stage lower battery warning system. When the batteries are
first detected to be weak, the first stage low
battery warning is indicated by
battery symbol flashing on the LCD display. At your earliest
convenience, you need to replace the batteries with 2 new AA
alkaline batteries.
When the batteries become too week for normal operation, the
thermostat enters the second stage low battery warning which shuts
down the thermostat. In this condition, “BATT” flashes alone on the
display, and the thermostat will turn your system Off. Your system
will remain shut-off until the batteries are replaced.
Note: The thermostat will still keep the current Set Temperature and Filter run time in
memory until new batteries are installed. After confirming that new batteries have been
inserted, the thermostat will return to normal operation.
Error Mode
If the thermostat is unable to control your system due to an unexpected battery problem,
the thermostat will enter Error Mode. In this condition, the
thermostat flashes “E1”or “E2”on the LCD display, and shuts off
your system. To correct this problem, replace the batteries with 2
new AA alkaline batteries, even if you have recently replaced them.
Move the battery out hold any key then place the battery again. You
will need to reprogram your thermostat and confirm normal
operation.
If Error Mode returns, please call us for further information.
Auto Cut Off
Your thermostat will automatically cutoff in Heat mode if the room temperature rises
above 95˚F (35˚C). It will cutoff in Cool mode if the room temperature drops below
40˚F (4˚C).
Note that if your system has malfunctioned and no longer responds to thermostat
controls, the Auto Cut-Off will have no effect.
