SWING (HVAC cycling rate) This feature allows you to set the desired variance in temperature
between the CT30 setting and the room temperature required before the heating or cooling system
will turn on—from 0.5° to 2.0° F (.25° to 1° C). For example, if SWING is set to 2.0° F and the CT30
is set to 70°F Target Temperature, the heat cycle will start when room temperature drops to 68°F.
Similarly, the cooling system will start when the room temperature increases to 72°F. The HVAC then
runs and will shut off at the Target Temperature.
To set SWING:
Touch SWING.
Touch the left/right arrows to set the SWING from 0.5° to 2.0°F.
The HVAC will run more frequently at .5°F and less at 2°F. Default is 1°F.

CALIBRATE
Your thermostat was accurately calibrated at the factory to ±1° F of actual ambient
temperature. You do have the option, however, to change the display temperature to match that of a
previous thermostat, or to match another thermostat already in your home. The range of change is
from -6°F to +6°F or -3°C to +3°C.
To change your Thermostat Calibration, touch MENU and then touch CALIBRATE.
Use the + / - to adjust the displayed temperature up or down, as desired.
The DELTA FACTOR that appears on the screen will also automatically increase or decrease
for each 0.5° (F or C) adjustment so you can see your change. The large display will show the
modied temerature reading that will be displayed on the HOME screen and used as the new room
temperature.
Touch to return to the Home screen.
DIFF (Used for 2 stage normal or heat pump with auxiliary only, not on screen for single stage)
The differential is the number of degrees between the room temperature and the Target Temperature
at which the 2nd stage will be used. Default is 2°F.
Touch MENU and then DIFF. Use the arrows to set the DIFF.
Recommend 2°F for very cold climates and the 4°F for warm climates.

MANUAL Screen Functions
The CT30 has 4 manual override commands. The manual screen is accessed by touching the large
current temperature display in the middle of the HOME screen.
IMPORTANT: The Mode must be in HEAT or COOL to access the manual screen.
TEMPORARY override Touch the + / - arrows to select your desired temporary Target
Temperature. Touch HOME to return to operation. The TEMPORARY icon will display indicating
you have modied the Target Temperature for the current Time Slot only. It goes back to the
program target at the next period. Also, when in TEMPORARY, if the target is set the same as the
programmed target for that period, the word TEMPORARY will go out.
HOLD This will hold the target temperature you set indenitely, until you turn HOLD off. HOLD will allow
you to operate your thermostat as a manual thermostat. It will keep whatever temperature you set until
you change it or cancel hold. Take care using the HOLD function as the program is now bypassed. To set
a hold target temperature, touch HOLD and use the +/- icons 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 the manual screen and de-select HOLD by touching it. Hold
is also canceled when you set the mode to OFF.
HOLIDAY This is a single program that repeats day after day until you turn it off. It supersedes the

PG 14
PG 14
weekly program. To use it touch HOLIDAY on the temporary screen. The default holiday program is
shown below. To modify this program, touch the PROGRAM button and then touch the DAY area until
HOLIDAY appears (after SAT). The default HOLIDAY program is set as 2 time slots; all day (same
target MORN, DAY and EVEN) and a different target for NITE. [Default program: HEAT 70oF all day
and 62oF at night. COOL 78oF all day and 82oF at night.]
EMER (in HEAT PUMP type)
If you set your CT30 for HEAT PUMP with auxiliary heat, EMER function is available on the MANUAL
screen. If you touch EMER, it displays EMER|ON. Your HEAT PUMP is disabled and auxiliary heat
is your sole source of heat. This manual override stays active until you toggle EMER off. Auxiliary
heat is more expensive than the heat pump so use EMER only if the heat pump cannot keep up or is
defective.
Other Functions
Save Energy Button
The “Save Energy” feature on the CT30 provides a simple, easy-to-use way to help you manage your
energy use. SAVE ENERGY automatically adjusts your Target Temperature up in COOL or down in
HEAT by 4oF. To use Save Energy, press the Save Energy button in the upper left corner of the unit.
The screen will now read “Save Energy”. To return to normal operation, press the “Save Energy”
button again. This is useful to save energy if you are gone for a short time.

The mode button sets the CT30 to HEAT COOL or OFF modes. Press it once to step to the next
mode. If the CT30 is in OFF and you want to return to the mode you were previously in, touch the
OFF indicator on screen.
FAN Button
The fan control is normally in AUTO mode, meaning that the fan operates automatically with the
HVAC system and the thermostat. When the fan button is pressed the fan goes ON; the fan will run
continuously in this manual override until switched back to AUTO by pressing the FAN button again.
[NOTE: Fan ON function is available in the OFF mode to allow simple ventilating.]
Simple Screen
This display mode limits the amount of information on screen and limits the functions to just the +/-
arrows and the MENU button.
Hold down the PROGRAM button for 12 seconds to access the limited display screen.
Hold down the PROGRAM button for 12 seconds to leave the limited display screen.

Compressor Protection The CT30 has a minimum cycle time of 4 minutes to protect your
compressor in cool and in heat pump (if you have one). The Home screen will show a small clock and
A/C during this time and the compressor will not come on until the 4 minute delay is over.
Communicating Thermostat
The CT30 has 2 RTM-1 radio ports. These allow your thermostat
to communicate with other systems.
Using USNAP Radios The USNAP ports allow you to connect
your CT30 to a wireless 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 efcient energy management sites that
can help you save money and protect the environment.
To Insert a USNAP radio module:
Power off the CT30. Insert the radio module in either slot on the
back of the CT30. Power up CT30.
To connect to a network follow the instructions that came with the
USNAP module.
