RCT-21
Radio temperature sensor
4-channel radio temperature sensor for cooperation with NTC 10k sensors. The device has 4 inputs. It can therefore measure external, internal, boiler and air temperature. This makes it easier to build advanced temperature control functions. Logical functions allow you to control the temperature depending on the user’s needs
– temperature measurement in the Exta Life system,
– wide measurement range (depending on the NTC sensor),
– sending the measured temperature value to the EFC01 controller,
– long operating range (up to 350 m),
– radio transmission (f = 868.50 MHz).
