Heater operation
The Rondo heater is a reserving heater as regards its function. This means that the heater has a
thermo-insulated stone space which maintains a certain basic heat with simmering mode which is
smaller than the heater power. This enables using sauna without long heating times thus differing
from the normal heaters which are heated for one-off use. Due to its large stone space the heater
offers plenty of heat.
Setting the heater for simmering mode
The main switch disconnecting the electrical output to the heater is located in front of the heater in
the lower edge. This switch can be used to disconnect the heater from power if the heater is not
used for a long period of time (for example when leaving for a holiday). In normal use this switch
should always be in the ON position.
The lid of the heater has to be closed when using the simmering mode.
When the power is connected using the control panel switch button, the upper led display starts
flashing and indicates the latest set simmering mode. The latest set temperature will always be
stored in the memory. The temperature can be set with the + and - buttons once the upper display
is flashing. The setting range for the simmering mode is 150 - 250°C. The change of the setting is
stored in memory by pressing the OK button or alternatively by waiting for about 3 seconds when
the controller stores the change automatically. Then the heater connects the simmering mode on.
When the heater is on simmering mode, the lower led display indicates with dashed lines the
simmering mode in relation to the requested temperature. The upper display indicates the current
temperature of the stone space. The required simmering mode has been reached once all the
three dashed lines are lit.
