Electric features Description
Temperature probe of the external air, located at rear, air inlet of the
heat pump
Water temperature probe, positioned on the return pipe of the heat
pump
Water temperature probe, positioned on the delivery pipe of the heat
pump
Electric features Description
Remote external air temperature probe. It can be used as alternative to
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
"LOW" temperature (radiant), contact your authorized service center;
accumulation inertial system with par.110 = 2. Contact your authorized
service center.
