Base Module Mounting Tips
Range between the thermostat and the base module is up to 100 feet
with no obstructions and up to 50 feet through standard building
materials. To optimize the range try placing the base module with no
metal between it and the thermostat.
The base module is designed to be mounted behind the front grille
of a packaged terminal air conditioner (PTAC). Refer to the PTAC
manufacturer’s manual for instruction to remove the front grille.
Check clearance to ensure the t of front grille after base module
installation. See below for a few location recommendations.
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.

When Working With A Vertical Unit
1. Do not mount Module inside the cabinet of the unit, or in a
metal enclosure.
2. Mount on the outside of the unit to maximize wireless
communication.
When Working With A Metal Sleeve Cabinet, Room Cabinet,
or PTAC Cover
1. If cabinet has open bottom, mount the module just inside the
cabinet as close to the open bottom as possible without placing it in
danger of being bumped or touched by furnishings, vaccum, etc.
2. Another good module location would be on the underside of the
top of the cabinet or cover. Directly behind the open Louver/Grill.

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 G terminal.
Loosen the terminal block
screws. Insert wires then
retighten terminal block screws.
Place nonammable insulation
into wall opening to prevent
drafts.

Wireless Network Specications
• The thermostat will attempt to pair with the rst Base module it
“hears”. Do not attempt to create more than one“pair” at the same
time in the same place.
• To ensure paring success, place the T731W/O within a few feet of
the Base module while pairing. Once paired, the signal strength
tech menu can be used to ensure a robust wireless connection.
• Placing either device in or around large metal objects can severely
degrade the wireless range.
• The wireless network will automatically recover in the event of a
power loss or temporary signal loss.
