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

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 AAA 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“ BATT” flashing on the LCD display. At your
earliest convenience, you need to replace the batteries with 2 new
AAA 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
AAA alkaline batteries, even if you have recently replaced them. Move
the battery out, and then hold any key to release the rest energy. 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.
