start/stop times for additional occupied periods will be prompted.

PROGRAMMING NOTES

• If only 1 Occupied period is selected in step 1 on page 3, Occupied 2
and 3 programming steps are skipped. Further, if only 2 occupied
periods are selected, Occupied 3 programming steps are skipped.

• Heat and Cool set points for Occupied 1 are the same for every day
of the week. Heat and Cool set points for Occupied 2 and 3 can be
adjusted differently for each day of the week, if desired.

• If the start time is set later in the day than the stop time, the pro­gram will run from the start time to midnight and from midnight to the
stop time on the same day.

on Monday. In this example the program will run from 12:00am Mon­day to 8:00am Monday and again from 9:00pm Monday to 12:00pm
Monday.

• The Unoccupied settings take effect at all times when: (1) the pro­gram is on and (2) the current time is outside a preset occupied
period. For this reason start and stop times are not necessary for
unoccupied.

• If the same start and stop times are programmed in for an occupied
period, then it will run 24 hours.

• If one occupied period starts and stops within another occupied
period the lower occupied number has priority.

pied 3 is programmed to be “on” 24 hours, and Occupied 2 is pro­grammed to run that day, then Occupied 2 settings will take over from
Occupied 3 between Occupied 2 start and stop times.

• To program Occupied 2 and Occupied 3 modes repeat programming
steps for Occupied 1.

About Advanced Features and Operation

• CLOCK BACKUP — In the event of a power loss, the
thermostat internal clock will continue to keep proper
time for a minimum of 48 hours without external power
or batteries.

• TWO-STAGE OPERATION — The Second Stage of
heat (Heat pump models only) is turned on when (1)
the first Stage has been on for a minimum of two min­utes, and (2) the temperature spread from the set
point is equal to or greater than:

deadband, plus 2 degrees.

The Locked icon will disappear from the display.

• DRY CONTACT SWITCH — The terminals are ‘nor­mally open’. Closing or completing the circuit will
cause the thermostat to enter Occupied 1. This feature
allows an external device such as a Central Time
Clock, Occupancy Sensor, or a Telephone activated
device to force 1 or more thermostats into Occupied 1.
For the Dry Contact to work the thermostat must be in

• MINIMUM HEAT/COOL SET POINT DIFFERENCE —
The Heat and Cool set points will not be allowed to
come any closer to each other than the value set in
Advanced Setup

Step 5, on page 4

. This minimum
difference is enforced during Auto changeover and
Program On operation.

• ENERGY SA VING SMART FAN — If Fan On is
selected, the fan will run continuously at all times,
except in Off, and will only run if there is a heating or
cooling demand in Unoccupied periods.

• OVERRIDE — As explained on

page 3

, pressing the
Override button during a programmed, Unoccupied
period will force the thermostat into Occupied 1, tem­porarily, up to 4 hours. If the Override button is
pressed during an Occupied period, the thermostat
will be forced into Unoccupied and the occupied num­ber

(1,2 or 3)

, it was forced out of will be turned off,

only for that day.
During Override periods the set points may be

adjusted, but they will not be remembered after Over­ride ends.

• HEAT — First Stage = Heat Pump. Second Stage =
Heat Pump and Electric Heat.

• F AN PURGE TIMER — When this feature is activated,
the fan will turn on during Unoccupied at a preset
amount of time prior to Occupied 1. This preoccu­pancy fan purge timer may be set as instructed on

page4,Step12

, from 0 to 3 hours. 0 = this feature

turned off.

• KEYPAD LOCK — To prevent unauthorized use of the
thermostat, the front panel buttons may be disabled.
To disable, or ‘lock’ the keypad, press and hold in the
Mode button. While holding the Mode button in,

• HOLID AY MODE — Th is f eatur e f orc es the t hermosta t
into Unoccupied for a preset duration, up to 99 days.
The Holiday setup display is entered as follows:

1

HOLIDAY

2

The thermostat will enter the Holiday mode when the
clock crosses midnight.

During Holiday mode Unoccupied set points are
enforced.

The Override button is active during Holiday mode. It
will override to Occupied 1 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 Holiday imme­diately, enter the Holiday setup screen and select 0.

• SOFT START — This feature is utilized in multiple
thermostat installations controlled by the Dry Contact
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 thermostats
connected, at the same time. Each Soft Start number

Page 5

represents a multiple of 30 seconds from the Dry Con­tact closure. For example, 1 = turn on 30 seconds after

Dry Contact closure, 2 = turn on 60 seconds after clo­sure, 3 = turn on 90 seconds after closure, and so on.
See

page 4, 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 program­ming Occupied and Unoccupied periods, the thermo­stat 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 4.

When entering the Auto mode from Cool, the Heat and
Cool set point temperatures will remain spread apart
by the amount that they were adjusted, prior to enter­ing Auto.

For example: If the Cool set point was set to 80 while
in the Cool mode and the Heat set point was adjusted
to 70 while in the Heat mode, upon entering the Auto
mode the Heat and Cool set points would be 80 and

70. Both

set points 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 points closer together,
enter the Cool or Heat mode by pressing the Mode
button, then adjust the set point(s) closer together.

is limited to how close it can come to Cool by

Step 5, page 4

• 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 thermostat. The thermo­stat automatically recognizes when a Remote Sensor
is connected. When reading the temperature from the

remote, the degree icon
above the room tempera-

ture blinks once a second.

The Override button on
the Remote Sensor works
slightly different than the
Override button on the
front panel. Each press of
the ‘External’ Override

Optional Sensor

Optional

button 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 wraparound as the

Override button on the thermostat does, so the second
or greater button press 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 500 ft of 20 ga. or 300 ft of
18 ga. thermostat wire.

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 sec. All icons will appear. Press and hold in the
Fan button until Fd appears. This resets all factory set­tings. To calibrate room temperature

, press the Up
and Down buttons at the same time twice. At this point
use the Up and Down buttons to calibrate room tem­perature, if needed. Press the Mode button to return to
normal operatio n.
