Installation and Operating Instructions

AudioSense Option

Model: TSMU

C

US

®

IMPORTANT: The AudioSense option is designed to work with the Steamist Total Sense TSG generators and TSC spa control.

NOTE: This option will not work with the TSC-250 control

1) Select a location for mounting the TSMU module in a utility 

area or closet. The AudioSense has audio input jacks on the 
side of the module that should be conveniently accessible to 
plug in additional audio inputs. Do not install any part of this 
assembly in a wall. 

2) Secure to the wall with screws.  
3)  Make sure a 120 volt outlet is located next to the module 

mounting location. Plug the power cord after all connections 
are complete.  

4) Route the control cable from the module location to the TSG 

generator, or optional TSCH and/or TSA. The manners in 
which the cables are routed are dependent on what is best 
suited for the installation. There are multiple connection 
jacks in TSG generator(s), two in the TSA, two in the TSCH, 
and two on this module allowing for gangable connections in 
the most convenient arrangement (See figure 3 for the 
system wiring diagram).

5) The AudioSense option requires speakers which are 

purchased separately. Refer to the wiring diagram on figure 
3 for connecting the speakers to the control module.

1. Green Light: Power Light. This along with the blue and 

yellow light will flash momentarily when the power is first 
plugged in. This flash indicates the microprocessor is 
functioning and is a test for the lights.

2. Yellow Light: Communication Light. This light is an indicator 

that the AudioSense system is not communicating with the 
control. After the initial power up the light will continue to 
flash until communication is established with the TSC-450 
control. To establish communication, power to the TSC-450 
must be turned on or if power is already on go to the 
TSC-450 control and start a steam or shower cycle for a few 
seconds then stop or cancel the cycle. This will make the 
TSC-450 look for the audio system and establish communi-
cation. When the AudioSense module is communicating with 
the TSC-450 this light will be off. 

3. Blue Light: Bluetooth light. This light will be on steady when 

the Bluetooth signal is broadcasting and not paired with a 
device. When it is paired it will flash and when it is off it 
means that Bluetooth is turned off in the TSC-450 settings.  

For operating instructions see the TSC-450 operating instructions Pub. No. 300
