Caution
Warning: If you are setting up this thermostat for an AC unit with electric
heat, or gas furnace, it is imperative that the the “FAN OPERATION”
menu feature is set to ELE or GAS, which ever applies. The default
setting is GAS; if electric heat strips are installed and the default value
of GAS is used, it is possible that the electric heat strips can become
energized without the blower motor on when there is a call for heat.
Reference the Tech Menu Setup section on how to change this feature.

Removing the Private Label Badge
The thermostat should be installed approximately 4
to 5 feet above the floor. Select an area with average
temperature and good air circulation.
Do not install thermostats in locations that are:
• On an exterior wall
• In direct sunlight
• Where there may be concealed chimneys or pipes
behind the wall

Wiring
Wireless Range
Range between the TSTBM3H2CPH6W-A and the
base module is up to 100 feet with no obstructions
and up to 50 feet in standard residential metal,
brick, and concrete construction. To extend the
range try placing the base unit higher if in a
basement or further away from large metal objects.
1. 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.
2. Loosen the terminal block screws. Insert wires
then retighten terminal block screws.
Do not install the base module in locations:
Caution
• Where temperatures could exceed 150°F
• That could be exposed to rain or snow
• That could be exposed to freezing conditions
• That are behind a chimney
• Where high moisture is possible
The base module is NOT water or
weatherproof and should only be installed in a
conditioned space.
All components of the control system and the
thermostat installation must conform to
Class II circuits per the NEC Code.
Wire specifications
Use shielded or non-shielded 18 - 22 gauge
thermostat wire.

Base Module—Attic Installation
Attic installation of the base module should be
avoided. Instead, locate a closet near the air
conditioning unit, then mount the base module high
on the wall inside the closet or on the ceiling of the
closet. This location will insure the base module is
below the 150ºF maximum ambient temperature
specification.
For vertical mount put one screw top and one screw

between TSTBM3H2CPH6W-A
Master Thermostat and the Base
Module
TSTBM3H2CPH6W-A

Step 1.
LED Relay
Indicator
Easy, Two Step Communication Link
To set up the initial link between the Master
Thermostat and the base module please follow
these steps:
1. Press and hold the base module button for 3
seconds. The Blue LED will flash when ready to
receive initial signal from TSTBM3H2CPH6W-A.
(Base module must be powered by 24V. Blue
LED will be continuously on when 24V power is
present.)
2. Hold the Light key of the TSTBM3H2CPH6W-A
for 10 seconds, the Blue LED on the base
module will stop flashing after communication
has been established between base module and
the TSTBM3H2CPH6W-A.
Caution
Insert batteries in the TESTBM3H23PH6W-A
thermostat and have it in hand while at the base
module when performing the initial
communication setup. Having the two devices
together to confirm that communication has
been established will be much easier. Now
place the thermostat on the wall mounting plate
in its intended permanent location.
The Blue LED on the base module will be on
when power is present. The Blue LED will flash
3 times every time it receives a signal from
TSTBM3H2CPH6W-A. When a relay is on the
corresponding LED relay indicator will be on.
Re-linking the thermostat and Base Module is
not necessary for power outages or after a
thermostat battery change.
The base module contains multiple LED lights
indicating the status of the HVAC equipment
Using Multiple TSTBM3H2CPH6W-A
wireless thermostats
Although utilizing multiple TSTBM3H2CPH6W-A
wireless thermostats in one location are all centered
around 916 MHz, a random unique communication
code is established between a specific thermostatbase module combination. This random code will
enable multiple (100+) TSTBM3H2CPH6W-A
wireless thermostats to function in one installation
site without interfering with one another.
If the base module does not receive a signal
from the TSTBM3H2CPH6W-A Caution
for 15 minutes
it will turn off all relays until communication is
reestablished. The Blue LED on the base
module will also turn off to show
communication has been lost.
If communication has been lost for 1 hour and
if the freeze protection feature is enabled, heat
and emergency heat relays will be turned on.
The heat and emergency heat relays will turn
on for 10 minutes every hour if there has been
a call for heat in the last 24 hours.

• Equipment efficiency is maximized by large swings
• Equipment wear and tear is minimized by large

• The ideal swing is one at which the system runs as

homeowner being uncomfortable
The 1st stage will energize at 69°F and turn off at

off at 69°F. The 3rd stage will energize at 67°F and
turn off at 68°F.

• Modern systems are designed to run longer with
fewer cycles for best efficiency
• Staging systems are designed to be most efficient
on first stage (excluding dual fuel systems)
• Equipment life is reduced by frequent on/off cycles
• The 1st stage energizes at 1x swing, the 2nd stage
at 2x swing and the 3rd stage at 3x swing.

With a residential Bosch Heat Pump, it is

energizing the “D” terminal, the fan motor will slow
down to better dehumidify the air by over cooling.
