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.

TSTBM3H2CPH6W-A Wiring Notes:
- In systems with no emergency heat relay, a
jumper can be installed between E and W2
- Due to the internal circuitry, a voltage
potential will exist across any terminal and
common if that terminal is not connected to a
resistive load.
- Bosch Water Source Heat Pumps utilize “O”
type reversing valve operation. If your heat
pump utilizes “B” type reversing valve
operation, substitute the wiring for the “O”
terminals for “B”.

POWERING THE TSTBM3H2CPH6W-A
MASTER THERMOSTAT
If remote sensors (TSTBM-OTS--TW-A or
TSTBM-RRS--TW-A) are to be used with the wireless
system you must hardwire the TSTBM3H2CPH6W-A
master thermostat.
Once the base module and the thermostat have been
securely mounted and both have been completely
wired for the applicable system, communication can
be established between the two.

ESTABLISHING COMMUNICATION
BETWEEN TSTBM3H2CPH6W-A
MASTER THERMOSTAT AND THE BASE
MODULE
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 ash 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 ashing 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 conrm that communication has
been established will be much easier. Now
place the thermostat on the wall mounting plate
in its intended permanent location.
Caution
The Blue LED on the base module will be on
when power is present. The Blue LED will ash
3 times every time it receives a signal from
TSTBM3H2CPH6W-A. When a relay is on the
corresponding LED relay indicator will be on.
If the base module does not receive a signal
from the TSTBM3H2CPH6W-A 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.
Step 1.
LED Relay
Indicator
Caution
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 specic thermostat-
base module combination. This random code will
enable multiple (100+) TSTBM3H2CPH6W-A
wireless thermostats to function in one installation
site without interfering with one another.
Caution
The base module is not water proof.
Do not install the base module in the following
locations:
Behind a Chimney
Where Temp exceeds 150F
Where rain, snow or extreme hot/cold is
possible.

Balance Point:
The system operates differently when a balance
point is used on a dual fuel system. The balance
point outdoor temperature setting will be the
outdoor temperature at which the thermostat
chooses either the heat pump or gas furnace. For Example:
A balance point setting of 30ºF will turn on only the heat
pump above 30ºF and only the gas furnace below 30ºF. Y1
will be stage one above 30ºF and W2 will be stage one
below 30ºF.
