DESCRIPTION OF HOW THE UNIT OPERATES
CONTROL DEVICE
The ventilation equipment is controlled from a separate control panel or from the cooker hood. The speed of the supply air fan can be reduced, if needed, in
relation to the speed of the extract air.
If the ventilation unit is controlled from the cooker hood, it can be set to the appropriate modes At Home/Away and boost can be set to 30, 60 or 120 min.
The supply air temperature is controlled from the control panel. If required, reheating can also be switched off from the control panel.
- The air heater for reheating has a TC01 automatic thermostat for overheating protection and a manually resettable overheating protection TZ03 (set as 90 °C).
- The fans have automatic overheating protection.
OPERATION WHEN THE WARNING DEVICES TRIP
- When the reheater’s manually resettable overheating protection (TZ03) trips, it can be reset from the outside of the unit’s electrical cubicle.
- The overheating protection of the fans is automatically reset when the temperature has dropped below the preset value.
