Thermostat does not work properly
I received a high quality sauna that heats to 140 when set at 110,120,130. Setting at 140 gets 154 which is the max it heats to. Temp control is you opening the sauna door. Brochure boasts that this heats to 170. I paid 6,000 dollars for a sauna that has a temp range of 140 to 154 degrees. It was falsely advertised. Tech support stopped responding once i stated that they need to compensate or make right . Thermostat Does Not Work which has been a huge disappointment.
