DESCRIPTION OF THE FUNCTIONS
CONTROL FUNCTIONS:
The ventilation unit can be operated from a separate Smart control panel or a Swegon CASA cooker hood.
When the ventilation unit is controlled from the cooker hood in the Home/Away/Boost modes and for local extraction, the time can be set to 30, 60
or 120 minutes.
The supply air temperature is controlled from the Smart control panel. When necessary, the reheating function can also be switched off from the
control panel.
– Overheating protection for the reheating air heater: The air heater is equipped with a TC01 automatic thermostat with manual reset (preset limit
value: 90 °C) as protection against overheating.
– The fans have automatic overtemperature protective devices.
REMEDIAL MEASURES TO TAKE IF THE SAFETY EQUIPMENT TRIPS:
– If an overheating protection with manual reset trips, locate and correct the fault; then press the reset button inside the ventilation unit.
– The automatic overheating protections of the fans will reset themselves when the temperature has dropped below the setting value.
