SWING (HVAC cycling rate) This feature allows you to set the desired variance in temperature
between the CT100 setting and the room temperature required before the heating or cooling system
will turn onSwing range: 0.5° to 4.0°F (.25° to 2°C). For example, if SWING is set to 2.0° F and the
CT100 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 4.0°F (.25° to 2°C).
The HVAC will run more frequently at 0.5°F and less at 4.0°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

DIFF (Used for multiple stage systems 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. DIFF may be set to a different value for HEAT or COOL. Default
is 2°F , range is 2°F to 6°F (1°- 3°C).
To set the differential for the current mode, touch MENU and then DIFF. Use the arrows to set the
DIFF. Recommend 2°F for very cold climates and 6°F for warm climates.

MANUAL Screen Functions
The CT100 has 2 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, COOL, or AUTO to access the manual screen.
TEMPERATURE Touch the +/- arrows to select your desired Target Temperature. Touch HOME to
return to operation.
EMER (in HEAT PUMP type)
If you set your CT100 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
MODE Button
The mode button sets the CT100 to HEAT, COOL, AUTO, or OFF modes. Press it once to step to the
next mode. If the CT100 is in OFF and you want to return to the mode you were previously in, touch
the OFF indicator on screen.

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.]
RESET button The RESET button re-boots the CT100 processor. It does not effect the target
temperatures that have been stored in permanent memory.
Compressor Protection The CT100 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 icon
during this time and the compressor will not come on until the 4 minute delay is over.
RH% Display
To display relative humidity touch the time display on the HOME screen - touch again to return.
