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”.

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.
