Thermal Cut-Out (Thermic) - VTS Medical Systems VENTUS COMPACT VVS021c Instructions For Use Manual

5.3 THERMAL CUT-OUT (THERMIC)

The functionality of the thermostat is based on the properties of the bimetallic element - it
causes the contacts of the heater control circuit to open when the air temperature near the
thermostat is 65°C. After an emergency shutdown, the heater automatically switches on when
the air temperature drops by 20°C. After a deliberate or emergency (due to overheating) power
off, the supply fan must run for some time (0.5-5 min) so that the heaters reach normal
temperature.
!
! The thermal switch is an integrated, factory-fitted component of each heater patch - no
additional installation or electrical connection by the installer is required.
