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.

INSTALLATION TIPS

REMOVING THE PRIVATE LABEL BADGE

Gently slide a scredriver into the bottom edge of the
badge. Gently trun the screwdriver counter
clockwise. The badge should pry off easily. Do not

use force.

All Bosch thermostats use the same
universal magnetic badge. Contact your local
Bosch distributor to learn more about our
free private label program.

WALL LOCATIONS

The thermostat should be installed approximately 4

to 5 feet above the oor. 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

• Close to a window or door leading outside

• Close to objects radiating heat such as replaces,
lighting, space radiators, or any other appliance

• In areas that do not require conditioning

• In dead spots or where drafts can occur (behind
doors or in corners)

• Close to hot or cold air ducts

Pick an installation location that is easy for
the user to access. The temperature of the
location should be representative of the
building.

BASE MODULE—BASEMENT
INSTALLATION

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.

Do not install the base module in locations:

• 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.

WIRING

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.

All components of the control system and the
thermostat installation must conform to
Class II circuits per the NEC Code.

Wire specications

Use shielded or non-shielded 18 - 22 gauge
thermostat wire.

BASE MODULE SUBBASE
INSTALLATION AND WIRING

Vertical mount

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

specication.

For vertical mount put one screw top and one screw
bottom. For horizontal mount put one screw left
and one screw right.

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

electrical shock or equipment damage.

Mercury Notice: All Bosch thermostats are
mercury free. However, if the product you are
replacing contains mercury, dispose of it
properly. Your local waste management
authority can give you instructions on recycling
and proper disposal.

Wire the base module’s subbase the same
way you would wire a hardwired thermostat
subbase.

To establish communication from the base
module to master thermostat, refer to the
directions in the TSTBM3H2CPH6W-A
Thermostat-Base Module Communication
setup procedure below in this manual.

BATTERY INSTALLATION

Battery installation is optional if there are no

remotes connected to the Master Thermostat (C
terminal connected). If you connect an outdoor
remote and/or indoor remote sensors it is required

the thermostat be hardwired.

To ensure a solid t between the thermostat

and the subbase, mount the subbase on a

at wall with the drywall anchors ush to the

wall. Using the screws and drywall anchors
that were provided with the thermostat.

The TSTBM3H2CPH6W-A can be battery
powered only if used as a stand-alone
thermostat solution. The TSTBM3H2CPH6W-A
must be hardwired (C and R terminals
connected to 24V power) if remote sensors
(TSTBM-RRS--TW-A or TSTBM-OTS--TW-A)
are used.

On the back of the thermostat insert 2 AA

MOUNT THERMOSTAT AND BASE
MODULE

Align the 4 tabs on the subbase with corresponding
slots on the back of the thermostat or base module.
Then push gently until the thermostat or base module.

To insure a solid t between the

thermostat and the subbase:

1. Mount subbase to a at wall

2. Use screws provided

3. Drywall anchors should be ush with the wall

4. Wires should be pushed into the wall
