Antifreeze
Automatic protection against too low temperature in the
room. When temperature in the room drops below de-
sired temperature, LEO and LEO KM units are turned on:
• valves (if installed) opens,
• fan is turned on at 100% of e ciency,
• LEO KM dampers are closed, unit operates using recircula-
ting air.
Units operate until the temperature in the roomis higher
of 1
C than antifreeze temperature, protecting the hall
o
against too low temperature inside and freeze of heating
medium in the exchanger.
