Due to room temperatures which are too high, not only is energy senselessly wasted, the reduction of the relative humidity in many areas is unhealthy.

The desire for warmth in the room temperature increases with quiet, stationary activities (watching TV, reading, etc.) or with non-physical work (office, PC, etc.). The temperature reached is no longer perceived by oneself and only discovered when another person enters the room.

Temperatures of more than 25°C and in part above 27°C, result. These temperatures are undesirable and can only be determined using individual thermometers in the rooms.

The SPV 5 with an integrated digital thermometer shows the temperature exactly at the spot on the thermostat head where the temperature is also measured.

A quick glance at the SPV 5 is all you need to know the exact temperatures.

In the living spaces, a relative humidity of 45–55 % is recommended.

The mean relative humidity of 50% is reached at 20°C with approx. 7.3 g/kg absolute humidity (air pressure 1013 mbar).

With the same prerequisites, a relative humidity of only approx. 40% is reached with an increase in air temperature to 24°C. This exceeds the recommended value significantly.

With the same prerequisites and an increase to 29°C, only a relative humidity of approx. 30% is reached.

Especially in winter with low outside temperatures and thus with low humidity capacity, the warmed room air is already disadvantaged and has only low humidity.

By breathing in the dry air, more moisture is withdrawn from the body by the respiratory organs in addition to evaporation on the skin surface.

A greatly reduced amount of humidity is very unfavourable for respiration and thus oxygen absorption. Oxygen is introduced less efficiently into the bloodstream over the alveoli. The skin requires the recommended relative humidity so as not to dry out because this is in symbiosis to the skin hydration. The low evaporation protection of the mucous membranes makes this dependent on the incoming humidity. If the mucous membranes have insufficient humidity, it can lead to increased nosebleeds; if skin hydration is too low, it weakens the immune defence (increased susceptibility to colds) and can lead to skin reddening and infections.

Overall the temperature setting is extremely important especially with allergy sufferers, immune-compromised people and older people.

The SPV 5 thermostat head gives you this control.
