CT1700A ultrastat ™ MOTION-ACTIVATED
LINE VOLTAGE THERMOSTAT
Programmable control for baseboard heaters.
Temperature Setting Range: 44 F to 80 F [7 C to 27 C].
Motion Detection: Infrared detection up to 23 ft [7m]; 60 degrees vertical
and 110 degrees horizontal viewing angle.
Light Detection: Photoresistive element with adjustable light level
sensitivity.
Switching: Triac based (spst).
Ratings: 10.5A maximum at 208 to
240 Vac, 50/60 Hz, 2500W. (To
determine baseboard wattage,
check the nameplate or
measure the length of the
baseboards the thermostat will
control. Generally, if the length of
the baseboards is more than ten
feet per thermostat, the wattage
is probably over 2500W. You
need to call an electrician.)
Not for use with central heating
systems or fan-forced heaters.

Tap the SEL key to move between modes. The
display changes in the following order: occupied-
light, unoccupied-light, unoccupied-dark, occu-
pied-dark, L, F or C.
NOTE: To lessen temperature changes when an
occupant leaves an area, the CT1700 will not
change from an occupied to unoccupied
setting for 60 minutes (light setting) or for three
hours (dark setting). If you notice your pet
activating the program, cover up the lower half
of the sensor window or program temperature
changes for only light and not occupancy.
YOUR HONEYWELL THERMOSTAT
Your new Honeywell CT1700 adjusts room temperature to
maximize comfort and energy savings by sensing light and
motion. It provides 15% to 23% energy savings compared to
nonprogrammable electric heating thermostats. The CT1700
replaces any two-wire, spst, line voltage thermostat used for
controlling electric baseboard heat.

Program Light Level
Consider the ambient outdoor and
indoor lighting over a 24 hour period
when setting the light level. The three
light level settings are: L1—the most
sensitive so it is used when you want
the thermosat to respond to a low light
level, like the TV or reading light; L2—
average setting so it is used for most
rooms; L3—the least sensitive setting
so it is used in well-lit areas.
Tap the SEL key until the LCD
displays L1, L2 or L3. Tap the
SET key to change the light
setting.
Review Program
Tap the SEL key to scroll
between settings. If you want to
change any setting, tap the SET key
until the display shows the desired
setting.
Make certain that your
heating system is
working, especially if it has
been inoperative for a length of
time. If the system does
not work, contact your local elec-
trician for assistance.

Reading Current Temperature
Tap the SET key. The room
temperature and four indicators
will be displayed for about ten sec-
onds. The display range is 40 to 86 F
[5 to 30 C]. When the room tempera-
ture is warmer than 86 F [30 C], the
two upper indicators will be displayed.
When the room temperature is colder
than 40 F [5 C], the two lower
indicators will be displayed.
Loss of Power
The CT1700 maintains the program
during loss of power without batteries.
The display will go blank and when
power is restored, the display will go
through the steps in the CHECK OUT
THERMOSTAT section.
