Product specification

Window opened or closed? Heating on or off? Creating the ideal indoor climate it’s usually not so easy. The TWIN PLUS wireless thermo-hygrometer from TFA is here to help.
Internal sensors measure indoor temperature and humidity.
The control of the indoor climate ensures a pleasant living environment and also prevents mould growth.
A separate wireless transmitter determines the outdoor temperature and humidity at the location and thus provide important information for home, garden, leisure and work.
Daily highest and lowest values are permanently displayed and automatically reset. The values are directly evaluated and a comfort-level indicator appears depending on the indoor climate. A temperature and humidity alarm can be adjusted, so you can control the indoor climate and maintain the values within the ideal range. A frost symbol appears on the display by impeding lower temperatures
