Amerec saunas are definitely the best and highest quality saunas in the United States, the way that the heaters are designed is not comparable to any other in the market. In this case I was replacing an old viking sauna heater that was no longer working. The hardest part of these installations is running the new cables for the control and sauna light, once this is done the other components are installed. The A30 control is really meant to be used by the club manager in a commercial setting and the commercial on/off button is installed in an area easy to reach by the users making it easy to operate. I installed the on/off control where the old viking timer was outside the sauna and the A30 timer higher than that, where it would be obvious that the daily users just need to turn the sauna on with the regular on/off timer, the duration of the session and temperature is preset by the club manager, in this case 180 degrees for 30 minutes and every time the on/off button is pushed the control defaults to these settings and automatically turns on the sauna light. The sauna is working very well making the spa users very happy but most importantly the club manager!
