o) Comfort Indicator
"DRY", "COM" or "WET" is displayed between the indoor and outdoor temperature/
humidity values.
These are so-called comfort indicators calculated from the temperature and
humidity.
Display Temperature
DRY -5 °C to +50 °C
(+23 °F to +122 °F)
COM +20 °C to +23 °C
(+68 °F to +73.4 °F)
WET -5 °C to +50 °C
(+23 °F to +122 °F)
No display <+20 °C or >+23 °C
(<+68 °F or >+73,4 °F)
The comfort indicator gives you a quick estimate of the existing ambient
conditions at the place of installation of the basis station or the three outdoor
sensors.
"DRY" = too dry
"COM" = ideal
"WET" = too wet
In case of a wet indoor environment there is the danger of mould formation
when humidity condensates on cold walls, e.g. if the outer walls or windows
are not sufficiently insulated.
