Taking a Steam Bath
On your ThermaSol MicroTouch Control, touch and 
release the power icon twice to power on. To turn off 
the steam unit touch and release the power icon once. 
Power on is verified when the control face shows lit LEDs 
and turns dark if power is off. 
A steam session lasts 45 minutes and is loaded with 
previously saved temperature set point.
Setting or Changing the Temperature Set Point
Set the temperature of your ThermaSol steam shower 
by using the lit plus + or minus – symbols, which are 
located immediately to the left and to the right of the 
  power icon. An arc array of lit squares will appear 
from left to right. 
Increase the temperature by touching + symbol 
until desired temperature is displayed by the 
blue LED lights running clockwise to indicate an 
increase in temperature.
Reduce the temperature by touching – symbol 
and the array of LEDs will begin to turn off.
