Installation Tips
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
Wall Locations
Pick an installation location that is easy for the user to access. The temperature
of the location should be representative of the building.
Installation Tip
Do not install thermostat in these locations:

When performing an attic installation, instead of placing the
equipmentmodule in the attic, locate the closet nearest to the air
conditioning unit. We reccomend mounting the Equipment module
high on the wall inside the closet or on the ceiling of the closet. This
location will insure the equipment module is below the 150°F
maximum ambient temperature specication while also allowing easy
technician viewing.
Installation Tips
Do not install the base module in locations:
• That are behind a chimney
• Where temperature could exceed 150°F
• Where rain or snow or extreme hot or cold is possible
Note: This base module is NOT weatherproof.
Equipment Module -Attic Location
The PROsync System has been tested in many dierent types of building construction including wood, steel beam, and brick in spaces over
5500 square feet. The wireless range performs well across multiple oors successfully. The PROsync radios constantly search for open
channels to avoid interference and ensure messages are received. The PROsync system has been shown to reliably transmit data across
hundreds of feet indoors and over 1000 feet line of sight.

Wireless Communication Setup
Follow these steps to setup the PROsync Wireless System
1. Choose the equipment module location.
2. Remove the front cover and attach the equipment module to the wall.
3. Wire the equipment module to the air handler.
4. Snap the cover back on. The C terminal light should be illuminated
indicating the equipment module is powered.
5. Install batteries in the main thermostat and ensure it is communicating
with the equipment module. Any changes to the main thermostat
that create a call will now be displayed at the equipment module
in the LEDs associated with the terminals.
6. Choose the install location for the T755WHO. In the tech settings, check
the “Signal Strength” tech setting and ensure the value is greater than zero.
7. Remove the subbase and attach it to the wall using screws and
anchors in the box.
8. If you want to hardwire the thermostat, connect the R and C wires.
9. Snap the thermostat onto the subbase. Make sure the connection
is secure and the display is illuminated.
10. Add any additional remote sensors as desired.
Note.
Each time a message goes back and forth between the remote
thermostat and the equipment module, the light on the equipment
module will blink blue twice, and the antenna icon on the remote will
blink twice.
Getting to know your thermostat
The low battery indicator is displayed when the AA battery power is low. Replace the
batteries when the indicator appears. If the system is in the low battery state for an
extended period, the system will operate with reduced temperature control. If battery power
is lost, the system will cease operation even if the equipment module is still connected.

Caution:
Electrical Hazard
All components of the
control system and the
thermostat installation must
conform to Class II circuits
per the NEC Code.
Warning:
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.
Installation Tip
Max Torque = 6in-lbs.
Wiring
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 Gterminal.
Loosen the terminal block screws.
Insert wires then retighten the
terminal block screws.
Place nonammable insulation into
the wall opening to prevent drafts.

Failure to disconnect the power
before beginning to install this
product can cause electrical shock

Adding A Remote Sensor
Establishing communication between a remote sensor and
the equipment module
The main thermostat and equipment module in this package are linked at
our factory. Upon power up, they will automatically begin to communicate.
If you wish to add additional remote sensors, follow the instructions on this
page.
1. Press the PAIR button on the equipment module. The equipment
module will begin double blinking pink for 2 minutes while it listens for a
new remote.
2. Press and hold the light button on the unpaired remote sensor to be
added. The remote sensor will show “PAIRING” on the main screen.
3. When the remote sensor is successfully paired to the equipment module,
the LCD will display“PAIRED” and the equipment module Pair button LED
will blink green.
4. Repeat the process for additional remote sensors.

System Averaging
System Averaging will average all remotes together to provide a more accurate temperature of the entire home. Adjusting
the temperature from any remote will temporarily put that room in control of the system. If the upstairs thermostat reads
80 while the basement reads 70 the system will condition the home to a 75 ambient.
Scheduling
With scheduling the system you can make dierent rooms in control for each part of the day. For homeowners with
predictable schedules, this ensures each room will be the target temperature when scheduled to be used. Making the
kitchen in control in the morning, your home oce during the day, your living room in the evening, and your master
bedroom at night is a great hands-free approach to maximize comfort. To turn Scheduling on or o, see the
instructions for the “Program Mode” tech setting in this manual on page 22.
Occupancy Sensing (Last Seen Mode)
This is the perfect solution for homes with a single occupant with less predictable schedules, using the built-in
occupancy sensors moves the comfort around the home without the need for scheduling. As soon as someone
enters a room, it takes control of the system. To turn Last Seen Occupancy Sensing on, see the instructions for
“Occupancy Mode”tech setting in this manual on page 31.
Occupancy Sensing (System Average Mode)
This is an excellent solution for a home with multiple occupants. Each time a remote senses occupancy, it starts an
automatic, internal timer. The system is controlled using the average of the temperatures from only the remotes with
active timers. When a remote’s timer expires, the system removes that remote from the average. To turn System
Average Occupancy Sensing on, see the instructions for “Occupancy Mode” tech setting in this manual on page 31.

Two methods are available for
using occupancy sensing to run
the HVAC system providing
exibility to the homeowner
based on their family and
lifestyle.
In both methods, once the
Duration of Occupancy has
expired for all remotes, the
system will enter the
Unoccupied Mode.
NOTE: Enabling
either type of occupancy
control will enable the occupancy
sensor on all remote sensors as
well (if applicable).When no
remote sensors are connected,
available options are“OFF”and
“ON”(System Average).
OF=OFF
The occupancy sensor is o
and the thermsotat
defaults to a traditonal
programmable or
nonprogrammable
thermostat.
LS = Last Seen
This option only allows one
sensor to be in control at
a time. Any time a person
enters a new room, the entire
system will prioritize that
remote’s settings to condition
the entire home until another
remote takes control or
the Duration of Occupancy
expires, entering Unoccupied
Mode.This is a great solution
for a household with a single
occupant.
SA = System Average
This option allows multiple
sensors to be in control at
a time. If multiple remotes
sense occupancy
simultaneously, the system
will average all remotes
currently in Occupied Mode
together. Each remote will
drop o individually as
its Duration of Occupancy
expires. This is a great option

(If using programming)
All our programmable thermostats are shipped with an energy saving default
program. You can customize this default program by following the
instructions in the set program schedule section starting on page 38.
Programming
Your thermostat can be programmed to have each day of the week
programmed uniquely (7 days), all the weekdays the same with a separate
program for Saturday and a separate program for Sunday (5+1+1), or
non-programmable.
A Note About Programmable Fan:
The programmable fan feature will run the fan continuously during any
time period it is programmed to be on. This is the best way to keep the
air circulated and to eliminate hot and cold spots in your building.
