Installation and User Manual HELO Roxx Trend

2.3 Ceiling installation of the sensor

Ceiling installation of the sensor In ceiling installation, a 5-mm hole
must be drilled to the sensor case to allow any condensed water to
drain.
Do not spray water directly towards the sensor or splash water at it
with a sauna scoop.

2.4 Installing the Extra NTC sensor

The additional OLET 31 sensor is connected to the Ext NTC connector on the RJ10 circuit board. For more
details, refer to the switch diagram. The additional sensor is installed on the sauna room wall no more than 500
mm from the ceiling. Once the additional sensor has been connected to the circuit board, it is automatically
activated. This means that the temperature shown on the control panel is measured by the additional sensor.
The primary sensor installed above the sauna heater only has the limiter circuit that limits the maximum
temperature to 110 °C. Even if the temperature is set to 110 °C on the control panel, the maximum temperature
that can be shown on the panel is approximately 90 °C, as the primary sensor above the heater limits the
maximum temperature to 110 °C. Depending on individual preferences, the temperature of a sauna room is
typically set between 70 and 80 °C.

2.5 Sauna heater stones

Quality stones meet the following requirements:
- Sauna stones should withstand heat and heat variation caused by vaporisation of the water thrown on the
stones.
- Stones should be rinsed before use in order to avoid odour and dust.
- Sauna stones should have an uneven surface to supply a larger surface for the water to evaporate from.
- Sauna stones should be large enough, measuring about 50–80 mm to allow good ventilation between the
stones. This extends the useful life of the heating elements.
- Sauna stones should be piled sparsely in order to enhance ventilation between the stones. Do not bend the
heating elements together or against the frame.
- Rearrange the stones regularly (at least once a year) and replace
small and broken stones with new, larger stones.
- Empty the stone compartment regularly, at least once a year in private
use, remove small and broken stones and replace them with new ones.
- In commercial use this operation must be performed at least every
second month.
- Stones are piled so that they cover the heating elements. Do not,
however, pile a large heap of stones on the heating elements. For
a sufficient amount of stones refer to Table 1 on page 7. Any small
stones in the package of stones must not be piled on the sauna heater.
- The warranty does not cover defects resulting from poor ventilation caused by small and tightly packed stones.
- Structural clay tiles are not allowed. They may cause damage to the sauna heater that will not be covered
by the warranty.
- Do not use soapstone as sauna rocks. Any damages resulting from this will not be covered by the stove
warranty.
- Do not use lava stone as sauna rocks. Any damages resulting from this will not be covered by the stove
warranty.
- DO NOT USE THE HEATER WITHOUT STONES.
