The thermostats of the Alfa 72 can be programmed with the function cooling or heating and have a minimum and maximum alarm temperature.
The Alfa 72 has a range of -50/+50°C or 0/+100°C. Temperatures above -10°C can be read-out per 0,1°C
The Alfanet 72 has a network connection for read-out and data logging on the Alfanet PC software. The Alfa 72 does not have this network connection.
The Alfa 72 is supplied with 12Vac. A special transformer can be delivered.
