Always in the know with the temperature – with the TWIN wireless thermometer from TFA.
A separate wireless transmitter determines the outdoor temperature at the location; an internal sensor measures the indoor temperature. Daily highest and lowest values are permanently displayed and automatically reset. The temperature alarm is adjustable. A frost symbol appears on the display by impending lower temperatures.
Controlling the room temperature is an important factor for the creation of a comfortable and healthy living environment and it helps save energy. Even one degree of temperature reduction can save up to 6% on heating costs.
With the outdoor temperature, you get reliable and important information for your home, garden, leisure and work.
