WARNING:

 The default settings of the mySteamist™ interface device 

utilizes an unsecured network during the set-up process. This allows for 

the possibility that anyone can connect to, and take control of, your 

steam bath. Operating the steam bath for extended periods of time with 

the door open can damage the home. Do not connect this device until 

you are ready to attach it to your secured home network. Please take 

proper precautions to make sure your home network is secured. 

Installation:

IMPORTANT: 

Before installing the Wi-Fi interface make sure the 

generator and TSC-450 control are installed and tested for proper 

operation.
Find a location to mount the Wi-Fi interface within the range of your 

home’s router. The interface needs to be connected to the steam 

generator with the provided 10’ cable. Longer cables are available up to 

50’. 

1. Secure the interface to a wall or flat surface with the 3 screws 

provided.

2. Adjust the antenna to the vertical position 

(see Figure 1).

3. Connect the multiconductor control cable to the interface and 

route it to the steam generator. (see Figure 1)

4. Turn the power to the generator off and remove the top cover of 

the steam generator. Locate a knockout hole on the top left side of 

the generator to pass the cable through (see Figure 2). 

5. Connect the cable to the generator by plugging into one of the 

available jacks on the circuit board inside the generator 

(see Figure 2).

6. Secure the cable to the generator with the provided strain relief. 

Allow a few extra inches of cable inside the generator. Use 

available knockouts (see Figure 2). 

7. Replace the generator cover and turn the circuit breaker back on 

to the generator.

8. Remove the cover on the Wi-Fi interface by sliding the thumb grip 

to unsnap the cover (see Figure 1).

9. Check the lights on the interface. They should be as listed below. 

If not refer to the troubleshooting section on page 3. If the lights 

are as listed continue with the configuration (see Figure 1).

RS2: 

On green steady 30 to 60 seconds after connecting

WIFI: 

Off until programmed 

RS1:

 Blinking yellow

485: 

Blinking red. 

PWR:

 On red steady

Configuring with your mobile device 

(recommended):

Note: 

This method of configuration can only be done if you router is  

          broadcasting it's SSID (Network Name).

Compatibility Alert: 

For Apple iOS 10 (and higher) users ONLY, see 

Page 3.

Wi-Fi network that the Wi-Fi interface was configured to. 

b. Completely close the app and restart it.

c.  If it is still in demo mode press the Devices button on the 

top left corner of the main control screen. This will 

rescan for devices. 

d. If the app is still in demo mode, check that the RS2 light 

is on steady in the Wi-Fi interface. If not, restore the 

factory defaults and reconfigure the device.

2. The app does not start the steam bath. When memory button 

is pressed the spinning icon keeps spinning in the cloud 

(see Figure 6). Press the Devices button to rescan networks. 

If you come back to this same screen, check that the 485 light 

in the Wi-Fi interface is blinking. If it is not blinking, see 

“Troubleshooting Wi-Fi Interface Lights”

Troubleshooting - TSC-450 control version:

1. Press the drop down arrow         on the main screen. 
2. Press the Tools button. 
3. Press the Devices button.
4. Check the version number of “THIS CONTROL”. It must 

be version V200 or higher. If the version is earlier it will 

not work with the Wi-Fi interface. 

5. Press the power button to return the control to the 

desired screen. If the version was proper check if the 

485 light is now blinking. Checking the connected 

devices does a new scan and may have solved the 

problem.

your PC/Mac back to your home network.

10. The WIFI interface will restart and join the local network 

that you selected.  Wait approx. 1 minute for the interface 

to change networks. You are now ready to begin using 

your app. Open the mySteamist app on your device. It 

should search for the mySteamist interface before going 

to the control screen. If you did not see the search screen, 

press the devices button to refresh the search. 

11. Advanced settings:

a. To change from DHCP to a static IP or to enter a Net 

Bios Name you must do this with a PC/Mac. 

b. Open your browser and enter the current IP address of 

the device (this can usually be found on the manage-

ment console of you router or by opening the app on 

your mobile device and going to the tools screen) or 

use the hostname noted in step 5 of this section.

c. Once your PC/Mac has connected to the mySteamist 

device press the tools button and the advanced setting 

screen will show. 

d. Make the necessary changes and press save. 

Changing the mySteamist location name:

If you have more than one steam bath, with a mySteamist Wi-Fi 

interface, it will be necessary to give each of the interfaces a 

different name. This can only be done by powering one 

interface at a time and configuring each one with a unique 

name. First make sure your mySteamist interface has been 

fully configured and tested. Then you can change the default 

name, Master Bath, to a new name.

1. Open the app. From the control screen select the Tools 

button (see Figure 3).

2. Select the Location button and edit the name to a more 

appropriate name (see Figure 4). 

3. Press save and you’re ready to configure the next device if 

you have more than one.

Troubleshooting - mySteamist interface lights 

and reset switch:

1.  

PWR 

– Red light which is on steady when connected to 

power. The power for the Wi-Fi interface comes from the 

steam generator. If the light is out, check that the generator 

has power. If the generator has power, check that the green 

cable connections are clean and secure. Note: unplugging 

the green cable to the Wi-Fi interface while power is on will 

interrupt communication to the TSC-450 control. See the next 

light to see how to reestablish communication. 

2.  

485 

– Red light which blinks when it is communicating with 

the TSC-450 steam bath control Version 2.00. If the light is off 

momentarily start a memory cycle on the TSC-450 control. 

This will rescan for the Wi-Fi interface. Stop the cycle and 

check the 485 light is blinking. If it is still not blinking check 

that the cable connections are clean and secure and restart a 

memory cycle again to rescan for the interface. If the 485 

light is still off see “Troubleshooting – Check the TSC-450 

control version”.

3.  

RS1 

– Yellow light which blinks when the microprocessor is 

operational. If the light is not blinking, disconnect the green 

cable for 10 seconds and then plug it back in. This should 

reset the microprocessor. If the light still does not blink, the 

mySteamist interface device needs to be replaced.

4.  

WIFI 

– Green light which is on blinks when configured to 

work with your home Wi-Fi network. This light is off with the 

factory default settings.  If the WIFI light is on and the RS2 

light does not come on it may be necessary to restore factory 

defaults. This may happen if you change your password on 

your router or replace your router. To restore factory defaults 

see reset button.

5.  

RS2 

– Green light which is steady when the Wi-Fi is opera-

tional. This is an indication that it is broadcasting WiFi signal 

or connected to a home router. A blinking light indicates the 

device was not assigned an IP address. If this light is blinking 

press the reset button on the device and reconfigure.

6.  

RESET 

– The reset button is used to restore factory defaults. 

Press and hold the RESET button until the RS1 light goes off. 

If successful the WIFI light will go out and stay out. After 

resetting factory defaults it is necessary to reconfigure the 

interface.

Troubleshooting - mySteamist app:

1.  If the app is stuck in demo mode, this is due to not being able 

to connect to the Wi-Fi interface (see Figure 5). 

a. Make sure your mobile device is connected to the same
