DESCRIPTION OF THE FUNCTIONS

CONTROL FUNCTIONS:

The ventilation unit can be operated from a separate Smart control panel or a compatible 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 can be manually set with the water-heated air heater thermostat valve. Whenever necessary, the reheating function can be switched off by setting the thermo-

stat to the zero setting.

Summer operation: In the summer, the extract air is steered past the heat exchanger when the controller opens the bypass cover.

–

Freeze protection for water-heated air heater for reheating: The fans will stop if the return water temperature drops below 10 °C. The fans start again when the return

water temperature reaches the set value 16 °C

–

The air heater is equipped with a TZ02 automatic thermostat with manual reset (preset limit value 90 °C) as protection against overheating.

–

The fans have automatic overtemperature protective devices.

IF THE SAFETY EQUIPMENT TRIPS:

–

If an overheating protection with manual reset trips, it can be reset by pressing a reset button above the air heater.

–

The automatic overheating protections of the fans will reset themselves when the temperature has dropped below the setting value.

Swegon reserves the right to alter specifications.
