Please dispose of packaging waste in line with statu- tory regulations. DE: Use the disposal system organised by Viessmann. AT: Use the ARA statutory disposal system (Altstoff Recycling Austria AG, licence number 5766). CH: Packaging waste is disposed of by the HVAC contractor.
The mixer extension kit (accessories) is required to switch the mixer. Central cooling The Vitocal 222-S, type AWT-AC can be used for cen- tral cooling. Central cooling results either through a heating/cooling circuit or via a separate cooling circuit. For this, the refrigerant circuit is reversed and heat is extracted from the cooling circuit.
