Temperature indicator light & humidity warning
The indicator light is illuminated in 4 colours to help estimate the optimal room
temperature. According to health experts, the best ambient temperature for a
children's bedroom is between 16 and 21°C and the optimal sleeping tempera-
ture is between 16 and 18°C. The temperature in the room during play should
not exceed 21°C.
The optimal air humidity in the room should be between 55% and 60%. It is
important to adhere to the maximum lower (40%) and upper (80%) limits
for a healthy indoor climate. When the air humidity is below 40%, or exceeds
80%, the light will flash in 10 second intervals.
