Subbase Installation
The thermostat should be installed approximately 4 to 5 feet above the
oor. Select an area with average temperature and good air circulation.
• Close to hot or cold air ducts
• That are in direct sunlight
• With an outside wall behind
the thermostat
• In areas that do not require
conditioning
• Where there are dead spots
or drafts
(in corners or behind doors)
• Where there might be
concealed chimneys or
pipes

Vertical Mount
Horizontal Mount
For vertical mount put one screw on the top
and one screw on the bottom.
For horizontal mount put one screw on the
left and one screw on the right.
All of our products are mercury free.
However, if the product you are
replacing contains mercury, dispose of
it properly. Your local waste
management authority can give you
instructions on recycling and proper
disposal.
Pick an installation location that is easy for
the user to access. The temperature of the
location should be representative of the
building.

Thermostat Quick Reference
The low battery indicator is displayed when the AA battery power is low. If the user
fails to replace the battery within 21 days, the screen will only show the low battery
indicator but maintain all functionality. If the user fails to replace the batteries after
an additional 21 days (days 22-42 since rst “low battery” display) the setpoints will
change to 55˚F (Heating) and 85˚F (Cooling). If the user adjusts the setpoint away from
either of these, it will hold for 4 hours then return to either 55˚F or 85˚F. After day 63
the batteries must be replaced immediately to avoid freezing or overheating because
the thermostat will shut the unit o until the batteries are changed.

If you are replacing a thermostat,
make note of the terminal
connections on the thermostat that
is being replaced. In some cases
the wiring connections will not be
color coded. For example, the green
wire may not be connected to the G
terminal.
Loosen the terminal block screws.
Insert wires then retighten terminal

Features
Temporary and Permanent Hold Feature
When cool or heat is turned on, the thermostat will display HOLD
and RUN SCHED on the left of your screen when you press the
or button.
Temporary Hold: At this time if you do nothing, the temperature will
remain at this setpoint temporarily for 4 hours.
Permanent Hold: If you press the HOLD key on the left of your
screen, you will see HOLD appear below the setpoint temperature in
the display. The thermostat will now permanently stay at this
setpoint and can be adjusted using the or keys.
To Return to Running Schedule: Press the RUN SCHED button on
the left of your screen to exit either temporary or permanent hold.
Filter Change Reminder
If your installing contractor has congured the thermostat to remind
you when the air lter needs to be changed, you will see FILT in the
display when your air lter needs to be changed.
Resetting the lter change reminder: When FILT reminder is
displayed, you should change your air lter and reset the reminder
by holding down the second button from the top left side of the
thermostat for 3 seconds.

Wiring Tips
C Terminal
The C (common wire) terminal does
not have to be connected when the
thermostat is powered by batteries.
Wire Specications
Use shielded or non-shielded
18-22 gauge thermostat wire.
Installation Tip: Do not overtighten terminal block screws, as this
can damage the terminal block. A damaged terminal block can
keep the thermostat from tting on the subbase correctly or cause
system operation issues. Max Torque = 6in-lbs.
Power supply
Factory - installed jumper. Remove only when installing on a 2 transformer systems.
Swing Setting Tip
Temperature swing, sometimes called dierential or cycle rate, can be customized
for this individual application. For most applications choose a swing setting that is
as long as possible without making the occupants uncomfortable.

Note: This thermostat is
hardwire powered when the
24V transformer is
connected to the Common

thermostat.
Use either O or B terminals for changeover valve.
Optional 24 VAC common connection when thermostat is used in battery power mode.
Note: In many systems
with no emergency heat

This thermostat has a technician setup menu for easy installer
conguration. To set up the thermostat for your particular application:
1. Press the MENU button.
2. Press and hold the TECH SET button for 3 seconds. This 3
second delay is designed so that homeowners do not accidentally
access the installer settings.
3. Congure the installer options as desired using the table below.
Use the or keys to change settings and the NEXT
or PREV key to move from one step to another.
Note: Only press the DONE key when you want to exit the
Technician Setup options.
4. Press the DONE key to exit.
The swing setting often called
“cycle rate”,“dierential”or
“anticipation”is adjustable. A
smaller swing setting will cause
more frequent cycles and a larger
swing setting will cause fewer
cycles.
Cooling
Swing
The cooling swing setting
is adjustable from 0.2˚ to
2˚. For example: A swing
setting of 0.5˚ will turn the
cooling on at approximately
0.5˚ above the setpoint
and turn the cooling o at
approximately 0.5˚ below
the setpoint.
0.5 0.5˚
Swing Setting Tip
The second stage will turn on at 2x the swing setting. The second stage will
turn o when 1x the swing is reached. For example, if the swing setting is .5
degrees for heating and the thermostat is set at 70˚F, the rst stage will turn
on at approximately 69.5˚F. The second stage will turn on at 69˚F. The second
stage will turn o at 69.5˚F and the rst will turn o at 70.5˚F. If the third
stage is used, it will turn on at 68.5˚F and turn o at approximately 69˚F.
