MULTI-STAGE TERMINAL OUTPUTS
Refer to equipment manufacturers’ instructions for specific system wiring information.
You can configure the thermostat for use
with either multi-stage electric heat systems
or multi-stage gas systems. When configured
for electric heat, the G terminal (blower/fan)
will be energized on a call for heat.
This thermostat is designed to operate a
single-transformer system. If you have a twotransformer system, cut and tape off one
transformer. If transformer safety circuits
are in only one of the systems, remove the
transformer of the system with NO safety
circuits. If required, replace remaining
transformer with a 75VA Class II transformer.
After disconnecting one transformer, the two
commons must be jumpered together.
Use the terminal output information below to
help you wire the thermostat properly for
your multi-stage system. After wiring, see

INSTALLER CONFIGURATION
BEFORE TURNING POWER ON, please
read the following instructions. Before
operating the system, you must configure
the thermostat to operate properly with
your equipment.
The thermostat, as it comes from the factory,
is configured to operate a standard multistage electric forced hot air system with a
single stage air conditioning compressor.
In this configuration, the thermostat will turn
on the fan immediately on a call for heat. If
you are unsure whether your system requires
the thermostat to control the fan, contact
your furnace/air conditioning system
manufacturer or a qualified heating/air
conditioning service person.
Your new thermostat has an Installer menu,
which allows you to customize the thermostat
to meet your requirements. (The thermostat
also has a User menu and a Keypad
Lockout menu; these menus are explained
further in the Operating Instructions.)
The menu settings can be changed at any time
to meet system or personal requirements.
ENTERING THE CONFIGURATION
MENUS.
After properly wiring the thermostat, turn on
power to the system. Momentarily press
PROGRAM RUN to make certain the
thermostat is in the run program mode, then
press TIME FWD and TIME BACK at the
same time to enter the User Configuration
menu. When the display changes to the first
item in the configuration menu, release the
buttons. Then press and hold SET TIME and
SET DAY for approximately 3 seconds to
enter the Installer menu. The display will
change to show the first item on the Installer
menu (Electric Heat Fan selection). Use the
following text, along with the Installer table
on page 5, to guide you through the menu.
Once in the menu, you set each item to the
or
, then
proper selection using
momentarily press TIME FWD to change
the display to the next item or TIME BACK
to return to the previous item.
To exit the menu at any time, press PROGRAM RUN .
ELECTRIC HEAT FAN
CONFIGURATION.
(Installer table step 1.) This menu item
determines whether fan control will be
through the thermostat or through the heating
system. If you have an electric heat or other
system that REQUIRES the thermostat to
control the fan, set this item ON. This allows
the thermostat to energize the fan immediately on a call for heat. If you are unsure if
the system requires the thermostat to control
the fan, contact the equipment manufacturer
or a qualified heating and air conditioning
service person. If your system controls fan
operation (as with most fossil fuel systems),
set this item to OFF.
SET CYCLE HEAT, COOL
(ANTICIPATION).
(Installer table steps 2 and 3). These items
allow the cycle times in heating and cooling
to be increased or decreased. The factory set
values can be adjusted higher for longer
cycles or lower for shorter cycles.
NOTE: Some manufacturers still instruct you
to set the anticipator to the current draw of
the equipment. That instruction applies only
to mercury bulb or mechanical thermostats; it
does not apply to this digital thermostat. As
configured at the factory, this thermostat will
maintain an accurate temperature. No
further adjustment is necessary, although
you can use these menu items to customize
the performance of the thermostat to your
requirements.
The adjustment range for HEATING is from
1 to 40. The factory preset is 5. The adjustment range for COOLING is from 9 to 40.
The factory preset is 13. The cooling will not
go below 9 because compressors require a
longer cycle.
The chart below shows how this adjustment
range affects thermostat performance.
PROGRAMMABLE COOL FAN-OFF
AND FAN-ON DELAY.
(Installer table steps 4 and 5.) These items
allow a selection of 0 to 127 seconds of fanoff delay after the thermostat has satisfied the
call for cool, or a fan-on delay of 1 to 30
seconds on a call for cool.
HEATING
Anticipation Value Cycle Length
The fan-off delay allows the fan to continue
running after the compressor has shut off.
This distributes the cool air that would
otherwise stay trapped in the air conditioning
coils through the ducts. Ideally the timing
would be set so the fan shuts off just as the
cool air is exhausted. If this timing is set too
long the fan may begin blowing warm air
before it shuts off. Shortening the fan-off
delay will prevent this.
A short delay to allow the A-coil to cool
off before the fan turns on may be preferred. This also allows the compressor and
the fan to come on at slightly different
times, which allows full power to the
compressor on start up. Recommended
setting for fan-on delay is 10 seconds or
less. A system that does not have a high
head pressure cutout should have a delay of
10 seconds or less.
PROGRAMMABLE HEAT FAN-OFF
DELAY.
(Installer table step 6.) This item allows a
selection of 0 to 127 seconds of fan-off delay
after the thermostat has satisfied the call for
heat if ELECT HEAT FAN (step 1) is
selected ON.
The fan-off delay allows the fan to continue
running after the burner, heating element,
etc. has shut off. This distributes the heat that
would otherwise stay trapped in the ducts.
Ideally the timing would be set so the fan
shuts off just as the warm air is exhausted. If
this timing is set too long the fan may begin
blowing cool air before it shuts off. Shortening the fan-off delay will prevent this.
COMPRESSOR LOCKOUT.
(Installer table step 7). This thermostat is
capable of protecting the system against
premature compressor failure by “locking
out” the compressor for at least five minutes
after each cycle. When the thermostat is in
compressor lockout, the word COOL will
flash on the display. With heat pump
systems, the word HEAT will flash if the
lockout occurs during a heat cycle. During
this period, the compressor will not be
energized.

THIS FEATURE DUE TO POSSIBILITY OF EQUIPMENT OR PROPERTY DAMAGE, OR PERSONAL
INJURY.
COMPRESSOR SHORT TERM CYCLE
PROTECTION
If this thermostat has been configured to
provide short-cycle protection, during the
5-minute lockout period the thermostat
will lock out the compressor to allow
head pressure to stabilize. To override
this feature for one cycle while testing
thermostat operation, press SET TIME
and SET DAY buttons at the same time.
ECONOMIZER FEATURE.
(Installer table step 8). This item allows
longer Y1 cycles for cooling with outdoor
air.
the remote sensor for proper installation and
wiring.) After installing and connecting the
remote sensor(s) to the thermostat, use these
menu items to enable each remote indoor
temperature sensor (A, b and/or C). Note that
if SENSOR A, b or C are set to ON in the
menu, but no sensor is installed, or if the
sensor is not functioning, when you exit the
menu, CHECK STAT SYSTEM will be
displayed. To correct this, check for proper
remote sensor installation and wiring. If
necessary, return to the menu and be sure that
the remote sensor items are set correctly.
The temperature at each remote sensor can
be displayed by pressing the light button
twice within one second with the thermostat
in program run or hold mode. Temperatures
at the outdoor and indoor remote sensors will
be displayed with subsequent presses of the
light button in the following order (if
connected): outdoor sensor, sensor L, A, b, C.
(Installer table step 13). If you wish to sense
indoor temperature using ONLY the remote
sensor(s), use this menu item to disable the
temperature sensor in the thermostat
(designated as the L sensor).
When operating with remote sensor(s), the
thermostat will calculate an average of the
sensed temperatures in all enabled sensor
locations (A, b, C and/or L), then display the
average temperature as the room temperature. During programming, you can also
assign each enabled sensor different
priorities during different program periods.
This allows the system to maintain a
comfortable environment by giving higher
DISABLING AUTOMATIC
CHANGEOVER MODE.
(Installer table step 9). This thermostat, as
configured at the factory, provides automatic
changeover, which allows the thermostat to
switch between heating and cooling to
maintain temperature. In this configuration,
when you press the SYSTEM button, the
thermostat will go through HEAT-OFFCOOL-AUTO modes (HEAT-EMER-OFFCOOL-AUTO for heat pumps). Select
HEAT(-EMER)-OFF-COOL to disable the
automatic changeover feature.
OPTIONAL REMOTE TEMPERATURE SENSE.
(Installer table steps 10 through 12). Up to
three remote sensors (part # F145-1328) can
be attached to this thermostat to sense indoor
temperature at locations away from the
thermostat. Each sensor may be located as
far as 200 feet away from the thermostat.
This is an excellent feature if the thermostat
is in a poor location for sensing temperature
or if you want to install the thermostat in a
separate room to prevent tampering. (Refer
to the installation instructions included with
priority to occupied locations. At the same
time, efficient system operation is enhanced
by giving lower priority to unoccupied
locations. For detailed instructions on this
feature, see the Operating Instructions.
After using the Installer menu to properly
configure the thermostat for your system,
press PROGRAM RUN .
OUTDOOR TEMPERATURE
SENSE.
This thermostat can also display outdoor
temperature, if you install an outdoor remote
sensor with an outdoor temperature sensor
probe (F145-1378). Refer to the remote
sensor installation instructions for proper
installation and wiring. Refer to the Operating Instructions to enable this feature and
display outdoor temperature on the thermostat.
