Constant Emission or Set Temperature
You can use your sauna 2 ways.  You can either set
it for a specific temperature or you can set it for
Constant Emission.  

To set it for a specific temperature, push the
up/down arrows until the temperature is displayed.  
Leave it set at that temperature.  Every time you
turn your sauna on it will reach that temperature
and stay there.

To use Constant Emission set the maximum
temperature to the highest setting (158F).  Set the
time to 90 minutes.  You do not need to change
these settings after that.  Just turn on your sauna,
go in at 100 F and come out whenever you are
done (usually about 135 F).  If you like it hotter, go
in at 110 F, if you like it cooler go in at 95 F.  No
matter what temperature you go in at, it will still
take you about 10 to 15 minutes before you start
sweating.  

We recommend Constant Emission because that
way you will get the full strength of the infrared
throughout your sauna without the sauna turning
on and off to maintain a certain temperature.
