• HOLIDAY MODE — This feature forces the thermo-
stat into Unoccupied for a preset duration, up to
99 days. The Holiday setup display is entered as
follows:
The thermostat will enter the Holiday mode when
the clock crosses midnight.
During Holiday mode Unoccupied period set points
are enforced.
The Override button is active during Holiday mode.
It will override to the Occupied 1 period settings up
to 4 hours then return to Holiday mode. The dry
contact switch is ignored.
The thermostat will exit Holiday mode at midnight of
the final programmed day. To terminate the Holiday
mode immediately, enter the Holiday mode setup
screen and select 0.
• SOFT START — This feature is utilized in multiple
thermostat installations controlled by the dry con-
tact terminals. Assigning a unique soft start number
to each thermostat will stagger the turn on times,
even though the dry contact closes, for all the ther-
mostats connected, at the same time. Each soft
start number represents a multiple of 30 seconds
from the dry contact closure.
For example, no. 1 =
turn on 30 seconds after dry contact closure, no. 2
= turn on 60 seconds after closure, no. 3 = turn on
90 seconds after closure, and so on. See
page 3,
Step 13,
to configure the thermostat for Soft Start.
• DUAL SET POINT BEHAVIOR — The adjustable
set point range is: 35 to 99 degrees in Fahrenheit
and 7 to 35 degrees in Celsius. When in the modes
Heat or Cool, this adjustable range is unhampered.
When adjusting any Auto mode, including program-
ming Occupied and Unoccupied set points, the ther-
mostat will not allow the Heat set point to get closer
to the Cool set point than the value programmed as
the minimum difference in
Step 5, page 2.
When entering the Auto mode from Cool, the Heat
and Cool set points will remain spread apart by the
amount that they were adjusted, prior to entering
Auto mode.
For example: If the Cool set point was set to 80 F
while in the Cool mode and the Heat set point was
adjusted to 70 F while in the Heat mode, upon
entering the Auto mode the Heat and Cool set
points would be 80 F and 70 F.
Both
set point tem-
peratures would then move up and down together,
(in this example spread by 10 degrees), by pressing
the up or down buttons.
To move the Heat and Cool set point temperatures
closer together, enter the Cool or Heat mode by
pressing the Mode button, then adjust the set point
temperatures closer together. Heat is limited to how
close it can come to Cool by
Step 5, page 2

• REMOTE SENSORS
(Optional Accessory)
—
When connected to terminals RS+5, RS, and GND
on the back of the thermostat, the thermostat will
read the temperature from the remote sensor and
ignore the temperature sensor inside the thermo-
stat. The thermostat automatically recognizes when
a remote sensor is connected. When reading the
temperature from the remote, the degree icon
above the room temperature blinks once a second.
The Override button
on the remote sensor
works slightly different
than the Override but-
ton on the front panel.
Each press of the
‘External’ Override but-
ton adds 2 hours to the
override timer. If the
timer was already active,
the first button press will
round the runtime to either
2:00 or 4:00.
Subsequent button presses will not wrap around as
the Override button on the thermostat does, so the
second or subsequent button presses will set the
runtime to 4:00. The Locked feature has no effect
on the external Override button. The
wired
remote
sensor is connected to the thermostat with
up to
450 ft of 22 gage, 300 ft of 20 gage or 150 ft of
18 gage thermostat wire
.
See the Remote Sensor
instructions for further details.
• FACTORY DEFAULTS — Before restoring factory
defaults, set thermostat to OFF mode. If, for any
reason it is desirable to return all stored settings
back to the factory default settings, press the Mode
button. While holding the Mode button in, press the
Fan button for 5 seconds. All icons will appear.
Press and hold in the Fan button until
Fd
appears.
This resets all factory settings.

temperature,
