RESET SWITCH
See the Troubleshooting section at the end
of this document for more information about
the function of this switch.
E2/P SWITCH
The E2/P switch is located on the back of the
thermostat body (see fig. 2). This switch
controls how the E2/P terminal of the
thermostat will be energized. When the
switch is in the E2 position (down), the E2/P
terminal will be energized only when in
emergency heat. When the switch is in the P
position (up), the E2/P terminal will always
be energized except when in emergency heat.
Consult the equipment manufacturer or a
qualified heating/cooling service person
before setting this switch. If your system has
no connection to E2/P, no change in the
switch setting is required.

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 single
stage heat pump system. In this configura-
tion, 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 (multi-stage/heat pump 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
proper selection using
or , then
momentarily press TIME
FWD
to change
the display to the next step or TIME
BACK
to return to the previous item.
To exit the menu at any time and return to
program operation, press PROGRAM
RUN
.
HEAT PUMP COMPRESSOR
CONFIGURATION.
(Installer table step 1) Use this item to select
the number of heat pump compressors and
how they are connected.
ELECTRIC HEAT FAN
CONFIGURATION.
(Installer table step 2.) 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 immedi-
ately 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. Note that with heat
pump systems, the fan always cycles with the
compressor.
SET CYCLE HEAT, COOL, AUX
(ANTICIPATION).
(Installer table steps 3 through 5). These
items allow the cycle times in heating,
cooling and auxiliary 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
9 to 40 for heat pump. The factory preset is
13. The adjustment range for COOLING is
from 9 to 40. The factory preset is 13. The
heating and cooling settings will not go
below 9 because compressors require a
longer cycle. The adjustment range for
AUXILIARY is from 1 to 40. The factory
preset is 6.
