Manual sauna heater with timer and temperature control knob.

Most important to know:
7. USING A SWITCHING CLOCK
– The switching clock is located on the lower part
of the stove. It works both as a
switch and a timer. The timer
can be used to set a desired heating time of 1-4
hours or a preheating time of 1-8 hours.
Function example:
– When you turn the knob on the clear area
in the scale to number 2, the stove switches on
immediately and the function stops in 2 hours.
– When you turn the knob on the black area
of the scale (pre-switching area) to number 4
the stove will be switched on in about 4 hours.
The stove is then switched on for approximately 4
hours.
– The stove can always be switched off
by turning the knob towards the sun to
the 0 position.
8. TEMPERATURE CONTROL
– The thermostat is located on the lower part of
the stove. With the thermostat you can select a
desired temperature in the sauna. The expanding
line in the scale describes a rising temperature.
When you turn the knob with the sun, the
temperature rises and when you turn the knob against
the sun, the temperature drops.
– The sauna heats up fastest when you turn
the thermostat to the maximum position.
– The size, starting temperature, thermal insulation,
uninsulated surfaces of the sauna and the way
the stones are stacked affect how
quickly the sauna heats up.
