Operation Guide CT80
The CT80 programmable communicating
thermostat operates via a high-quality, easy-to-use
touch screen. To program or adjust your CT80,
simply touch your nger rmly to the screen. The
screen will automatically light up. The screen will
respond differently to different types of touches, so
you may want to experiment with your nger or a
stylus (not included), to see what works best for you.
The “beep” sound is heard when the CT80 senses
a valid touch of the screen.

MANUAL Screen The Manual Screen control screen is where you can make
temporary changes to your CT80’s operation. The CT80 has 6 manual override commands. These
are accessed by pressing the +/- buttons or touching the current temperature on the HOME screen.
IMPORTANT: The Mode must be in
HEAT or COOL to access the manual screen.
Temporary OVERRIDE -
• Press the + / - buttons to select your
desired temporary Target Temperature.
• Press HOME to return to operation.
The TEMPORARY icon will display
indicating you have modied the Target
Temperature for the current Time Slot
only.
HOLD -
This will hold the target temperature
you set indenitely, until you turn it off.
Take care using the HOLD function. To
set a hold, touch HOLD to initiate a hold temperature. You can use the +/- buttons to select your hold
temperature. The HOLD icon will display on the HOME screen indicating you have changed the Target
Temperature. The system will HOLD this temperature until you return to this screen and de-select HOLD,

HOLIDAY PROGRAM - This is a single program that repeats day after day until you turn it off. It
supersedes the weekly program. To modify it touch PROGRAM on the MANUAL screen. It uses the
Calendar method for programming (see pg7 ).
VACATION - This function will hold a pre-set temperature until you turn it off. The preset is saved for
next time.
FRESH AIR - If you have a fresh air bafe connected to the EX terminal, the CT80 will use this
outside air source as the 1st stage of heating or cooling. Useful in desert climates where outside air
temp can change very quickly or just to freshen indoor air quality.
EMER HEAT - This is available if you have a HEAT PUMP with auxiliary heat. When you select this
your HEAT PUMP is disabled and auxiliary heat is your sole source of heat. This manual override
setting stays active until you turn it off. (This command is not displayed if you do not have a heat
pump). Remember auxiliary heat is more expensive than the heat pump.
Run the pre-set program
The CT80 comes pre-programmed with an EPA approved program. This program was recommended
by the EPA for energy efciency. We strongly recommend that you run this program for one week,
and see if it works for you. If it does not t your needs you can always input a custom program.
• To run the EPA program, press and select HEAT or COOL with the mode selection. Set the time
and day and Press HOME. The unit is now running the EPA program.

COMFORT The Comfort Settings on the CT80 allow you to maintain consistent comfort with
the highest levels of temperature control precision, accuracy and energy efciency.
HVAC CYCLING: This feature allows you to set the desired variance in temperature between the
CT80 setting and the room temperature required before the heating or cooling system will turn on—
from 0.5° to 3.0° F (.25° to 1.5° C). For example, if HVAC CYCLING is set to 2.0° F and the CT80 is
set to 70°F, the heat cycle will not start until the room temperature drops to 68°. Similarly, the cooling
system will not kick-in until the room temperature increases to 72°F. The HVAC shuts off at the target.

PG 9
To set/adjust HVAC CYCLING:
1. Press Menu and then touch “COMFORT.”
2. Touch the temp offset setting.
3. Use the +/- buttons to raise or lower the variance setting—from 0.5° to 3.0° F.
4. Press HOME to return to the Home screen.
2nd STAGE ON AT : This feature allows you to adjust the settings that control the next stage heating,
cooling, and AUX depending upon the climate you live in (see page 18 for more information). This can
be modied for maximum efciency or comfort. It is displayed for a multistage system in HVAC SET-UP.
To set/adjust 2nd STAGE ON AT:
1. Press Menu and then touch COMFORT
2. Touch and highlight the user setting (next to 2nd STAGE ON/AUX ON AT ).
3. Use the +/- buttons to raise or lower the setting—from 2.0° to 6.0°F (1.0° to 3.0° C).
The “NEVER” option allows the user to not use AUX heat except for EMER.
4. Press HOME to return to the Home screen.
RECOVERY - ECON or FAST - In multi stage HVAC systems, ECON takes a bit longer but uses less
energy to get to the Target Temp. FAST recovery uses all available stages all the way to target temp and
uses a little more energy (see page 18 for more information).
Chirp set - Touch this to turn the audible chirp sound on or off.
F/C Set - Touch this to switch the temperature display scale from oF to oC .

desired minimum humidity level.
4. The CT80 can be toggled <ALWAYS> run the
humidier when the humidistat calls for humidity (in
HEAT or cool with fan) or can be set to run only when
the humidistat is calling for humidity and the heat is also
running <W/ HEAT>.
DE-HUMID BY A/C - The CT80’s humidistat can also control the Air Conditioner for de-humidifying. To
set a maximum humidity level (using the air conditioner):
1. Press MENU, then touch the HUMIDITY, then view DE-HUMID by A/C.
2. Touch MAX 90% and use the +/- buttons to set the desired maximum humidity level.
(You cannot change MAX humid % until you set it to ALWAYS or HST+TST)
3. The CT80 can be toggled to <ALWAYS> run the air conditioner when the humidistat calls to de-
humidify or can be set to run the air conditioner only when the humidistat calls to de-humidify AND the
thermostat is also calling for COOL <HTS+TST> (HST=humidistat, TST=thermostat).

Communicating Thermostat -
The CT80 has 2 RTM-1 radio ports. These allow your
thermostat to communicate with other systems. Alarm
systems using the Z-Wave standard take advantage of
the CT80s control and monitoring features.
Depending on your area Power Company, programs
may be available to connect your thermostat to power
grid status information. This can make it easy for you
to moderate your energy use at peak hours and use
power when it is less expensive.
The RTM-1 ports also allow you to connect your CT80
to your home WiFi network. This can give you access to your home’s HVAC system even when you
are away. It can also give you access to web based efficient energy management sites that can help
you save money and protect the environment.
