ARMCHAIR PROGRAMMING
1. You can program your thermostat prior to installation by following these instructions
and starting at the configuration menu. This can be done while you relax in your favorite
chair and is a very good way to familiarize yourself with all the functions of your
thermostat.
The following time and temperature settings are pre-programmed into the thermostat:
Temperature in ˚F (˚C)
Program Number Time Heat
1 6:00 am 68˚F(20˚C)
2 8:00 am 60˚F(16˚C)
3 4:00 pm 68˚F(20˚C)
4 10:00 pm 60˚F(16˚C)
COMPRESSOR PROTECTION
2. The thermostat provides a 4 minute delay after shutting of the heating or cooling
system before it can be restarted. This feature will prevent damage to your compressor
caused by rapid cycling. Note that this delay also applies to the heating system control.
It does not provide a delay when there are power outages. You can select the function
on or off at the configuration.
TEMPERATURE RANGE
3. This thermostat can be programmed between 45˚F and 95˚F (7˚C and 35˚C).
However, it will display room temperatures from 30˚F to 99˚F (0˚C and 37˚C). "HI" will be
displayed if the temperature is higher than 99˚F (37˚C), and "LO" will be displayed if the
temperature is lower than 30˚F (0˚C).This thermostat will automatically cutoff in Heat
mode if the temperature rises above 95˚F (35˚C), and automatically cutoff in Cool mode
if the temperature drops below 45˚F (7˚C).
POWER SUPPLY
4. The thermostat is supplied with a Li-battery. You can charge the Lithium battery
through a USB cable (included) connected to a PC. During the charge process the
battery icon will flash on and off.
Note: The Lithium battery should be charged over 12 hours for the first 3 times to
properly condition the battery.

display. The Multi-stage configuration can be toggled to "SS1" or "HP1" by pressing the
up or down key. In Multi-stage configuration, EMER mode is useless.
2）This thermostat is configured from the factory to operate a heat/cool, fossil fuel (gas,
oil, etc.), forced air system. It is configured correctly for any system that DOES NOT
require the thermostat to energize the fan on a call for heat. If you system is an electric
heat or heat-pump system that requires the thermostat to turn on the fan on a call for
heat, locate the HE/HG in the menu and SELECT the HE position. This will allow the
thermostat to energize the fan immediately on a call for heat. If you are unsure if the
heating/ cooling system requires the thermostat to control the fan, contact a qualified
heating and air conditioning service person. When the thermostat is configured for Heat
Pump, the thermostat will always power the circulator fan on a call for heat in the HEAT
mode. The HE/HG must be set to match the type of Auxiliary heat your system uses for
proper operation in the EMERGENCY mode.
All wiring diagrams are for typical systems only. Refer to equipment manufacturers'
instructions for specific system wiring information.

Centigrade or Fahrenheit as required
8) Selects time format display 12hours or 24hours
9) Select Compressor Lockout COMP OFF or ON
Selecting COMP ON will cause the thermostat to wait 4 minutes before turning on the
compressor if the heating and cooling system loses power. It will also wait 5 minutes
minimum between cooling and heating cycles. This is intended to help protect the
compressor from short cycling. Some newer compressors already have a time delay
built in and do not require this feature. Your compressor manufacturer can tell you if
the lockout feature is already present in their system. When the thermostat compressor
time delay occurs it will flash the set point for about 4 minutes.
10) This mode is used to set the communication channels. The thermostat and controller
must be re-matched after changing channels.
11) Select "1" to restore factory default settings. This will require the thermostat and
controller to be re-matched.

information.
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 2˚F (2˚C) apart to
allow the Auto Season Changeover to occur when the appropriate temperature span
has been reached. There is a Designated Day Override or Permanent Override.
However, these overrides are not energy saving settings. Auto Season Changeover will
still function in Override 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 heat mode and turn on heat when
the room temperature falls below 68˚F.

temperature is already comfortable by the start of the comfort
temperature program period. Auto Recovery works in both Heat
and Cool modes.
■When the thermostat is in Auto Recovery mode, the display will
alternate "RECO" with time, and the program indicator will flash.
