Electric features Description
Remote external air temperature probe. It can be used as alternative to
NTC 10kΩ / 25°C
that on machine, after having disconnected the "Air Ext. S." sensor
It must be used: In systems with circuit "HIGH" temperature (fan coil)
and "LOW" temperature (radiant) with par. 110 = 1.
For the use of systems with circuit "HIGH" temperature (fan coil) and
NTC 10kΩ / 25°C
"LOW" temperature (radiant), contact your authorized service center;
accumulation inertial system with par.110 = 2. Contact your authorized
service center.
