you should touch a grounded metal object before the  
TX9000TS to minimize the risk of causing damage to the  
unit.  
3.1. TOOLS REQUIRED  
●
#1 Phillips screwdriver (small)  
●
Drill with 3/16-in. (4.8mm) bit  
●
Wire stripper/cutter  
3.2. LOCATION  
• Your thermostat is a precision instrument. Please  
handle it with care.  
On replacement installations, mount the new  
thermostat in place of the old one unless the  
conditions listed below suggest otherwise. On new  
installations, follow the guidelines listed below.  
• Locate the thermostat on an inside wall, about 5  
ft. (1.5m) above the floor, in a room that is used  
often.  
2. COMPATIBILITY  
The TX9000TS can be used with most 24 volt gas,  
oil or electric heating and air conditioning systems,  
single stage heat pumps or gas millivolt heating  
systems. It cannot be used with 3 wire zone  
valves, 120V systems, or multistage systems.

• Do not install it where there are unusual heating  
conditions, such as: in direct sunlight; near a  
lamp, radio, television, radiator, register, or  
fireplace; near hot water pipes in a wall; near a  
stove on the other side of a wall.  
• Do not locate in unusual cooling conditions,  
such as: on a wall separating an unheated room;  
or in a draft from a stairwell, door, or window.  
7. Press up on the  
thumb latch at the  
bottom of thermostat  
and separate the  
body from its base.  
8. Hold the base against the wall. Route the wires  
through the hole below the terminal block.  
Position the base for best appearance (to hide any  
marks from an old thermostat). Attach the base to  
the wall with the two screws provided.  
• Do not locate in a damp area. This can lead to  
corrosion that will shorten thermostat life.  
• Do not locate where air circulation is poor, such  
as: in a corner or an alcove; or behind an open  
door.  
NOTE:  
If you are mounting the base to a soft material like  
plasterboard or if you are using the old mounting  
holes,  
• Do not install the unit until all construction work  
the screws may not hold. Drill a 3/16-in. (4.8mm)  
hole at each screw location, and insert the plastic  
anchors provided. Then mount the base as described  
below.

14. Install two(2) Energizer or DURACELL "AA"  
size alkaline batteries at this time. For  
instructions, see "BATTERIES &  
MAINTENANCE".  
4. Loosen all screws on the old thermostat and  
remove it from the wall.  
15. Initially, your thermostat will display "SUN  
12:00 AM". To correct the display, refer to  
"Setting the DAY and TIME" in the "OPERATING  
INSTRUCTIONS" section of this manual.  
16. Install your TX9000TS on its base. To do this  
hang the top of the unit by the tabs on the base,  
then snap the bottom of the unit into place. Do not  
use unnecessary force. If the body does not snap  
into place easily, remove the body, re-hang it from  
the tabs and try again.  
3.4. MOUNTING THE TX9000TS  
5. Strip insulation leaving 3/8 in. (9.5mm) bare  
wire ends and clean off any corrosion.  
6. Fill wall opening with non-combustible  
insulation to prevent drafts from affecting the  
thermostat.  
CAUTION:  
Be careful not to drop the body or disturb electronic  
parts. Leave the cover closed while the body is being  
removed from the base.

4.9. SOFTWARE RESET  
• OVERRIDE will be automatically canceled at the  
start of the next program period.  
• OVERRIDE will be cancelled if the set  
temperature is adjusted to its programmed value  
or if the units mode is changed.  
This reset is disabled while the touchscreen is  
locked. When activated it will reset all  
programmable values and settings including the  
lock code and clock, to their default values. Then  
option switch positions will be read before  
resuming normal operation. Record your settings  
and programs before pressing this button.  
4.12. TEMPERATURE HOLD  
HOLD may be used for manual temperature  
control. It is the simplest means to set and  
maintain a fixed temperature in Heat or Cool,  
without concern for programming.  
NOTE:  
• Take care not to inadvertently press the SOFTWARE  
RESET button while programming your unit.  
• Touching HOLD toggles the unit into or out of  
the hold mode with the current status indicated in  
the display. In HOLD adjust temperature as  
desired.

6.2. SWING SETTING  
A thermostat works by turning your heating or  
cooling system on and off whenever the room  
temperature varies a certain number of degrees  
from the set-point temperature. This variation is  
the "swing." Your system should cycle on about 3  
to 6 times per hour. A smaller swing number  
increases the number of cycles, so room  
temperature is more constant. A larger swing  
number decreases the number of cycles, saving  
energy in most cases. To change the SWING value  
from the main menu:  
• Use UP/DOWN ARROW to change the flashing  
temperature setting for MON EVE.  
• Touch YES to accept the displayed temperature  
and advance to Set MON NITE start time.  
• Use the UP/DOWN ARROW to change the  
flashing start time for MON NITE.

advance to program temperature.  
• Use UP/DOWN ARROW to change the flashing  
temperature setting for MON NITE.

and advance to Set TUE MORN start time.

week.

7.2. SMART RECOVERY SWITCH #2  
The Program Lock allows the owners/operators to  
prevent unauthorized changes to the thermostat’s  
settings. When the thermostat is locked, a three  
digit code is set (000 to 999). That code must be  
re-entered before locked settings can be changed  
without performing a hardware reset of the unit.  
The status of the lock is indicated by an open or  
closed padlock icon.  
Smart Recovery allows your HVAC system to  
attempt to recover from a setback period and  
reach your desired comfort temperature set point  
by the beginning of your programmed comfort  
period. This option allows you to choose whether  
to use Smart Recovery.  
When enabled, Smart Recovery will initiate if:  
• Recovery is from an evening setback to  
morning comfort or day setback to evening  
comfort period.  
• In Heat mode the temperature set point of the  
comfort period must be higher than the setback  
period.  
• In Cool mode the temperature set point of the  
comfort period must be lower than the setback  
period.  
• The estimated Smart Recovery time must be  
longer than 15 minutes for a Smart recovery to be  
initiated.

repeatedly ignored by your thermostat. That is an  
indicator that you should modify your program so  
that the recovery can be achieved within the 1  
hour limit.  
• A Smart Recovery may not be initiated for 48  
hours after the units programs have been  
changed. This allows the unit to gather the data  
necessary to predict a Smart Recovery time.  
2. Remove the used batteries. See battery location  
and polarity in figure on Page 12.  
3. Install two new Energizer® or DURACELL®  
"AA" size alkaline batteries in the battery  
compartment. Observe the polarity marking  
shown in the compartment.  
4. Hang the top of the unit by the tabs at the top  
corners of the base, then snap the bottom of the  
unit into place. Do not use unnecessary force. If  
the body does not snap into place easily, remove  
the body, re-hang it from the tabs and try again.

option, repair or replace it. This warranty does not  
cover damage by accident, misuse, or failure to  
follow installation instructions. Implied warranties  
are limited in duration to three years from date of  
original purchase. Some states do not allow  
limitations on how long an implied warranty lasts,  
so the above limitation may not apply to you.  
Please return malfunctioning or defective units to  
the participating retailer from which purchase was  
made, along with proof of purchase. Please refer  
to "Technical ASSISTANCE" before returning

This table is printed on the circuit board. To  
change a switch position move switch down or up.  
After settings have been changed with batteries  
installed, press the Hardware Reset (H.W. Reset)  
button on the rear of the unit's circuit board for  
changes to take effect. See jumper and switch  
positions figure on Page 12.  
7.6. GAS/ELECTRIC JUMPER  
In HEAT mode, the position of this jumper controls  
when the thermostat requests the system fan to  
run. In Gas mode the fan is normally controlled by  
the heating system itself. In Electric mode, the fan  
is controlled by the thermostat. See jumper and  
switch positions figure on Page 12.  
8. BATTERIES AND MAINTENANCE  
The TX9000TS requires batteries to operate your  
heating/cooling system. Replace the batteries  
when the battery REPLACE indicator appears in
