Northern Lights Sauna Heater Controls All Northern Lights Sauna Heaters come with built-in
illuminated controls. The control functions are easy to understand and operate.
All you really need is to control the temperature and the duration of heating.
In the JM and KV heaters, the left switch is for temperature, and the right
switch is for time. The JM heater features a one hour operating timer. The KV
heater features an eight hour preset timer with a one hour operating time. The
Symphony features an air circulation control valve switch and a one hour timer
for operating at full power. It normally takes about half an hour to heat up a
sauna, except with the Symphony heater. The one hour operating timer was
designed to heat up a sauna and provide half an hour of continuous bathing
temperature. It also provides ease of mind as you will never forget your heater
on. To program more than one hour of operation, simply turn the timer switch at
any point of your sauna stay.
