Proceed as follows:

1. Filter: Select the following properties, if applicable:

   • Space heating All systems provide hot water for heating.
   • Domestic hot water
   • Bivalent (with boiler)
   • Solar thermal system

2. Only systems including the selected properties are displayed below.

3. You can switch the system View between List and system Icons.

4. Click on the desired heat pump system (HPS). Air heat pumps are shown here as examples.

   #	HPS	Space Heating	Domestic Hot Water	Bivalent boiler	Solar Loop
   HPS 1		direct	-	-	-
   HPS 1.1		monovalent tank	-	-	-
   HPS 1.2		monovalent tank	-	space heating	-
   HPS 2		direct	monovalent tank	-	-
   HPS 3		direct	bivalent solar tank	-	DHW
   HPS 4		combination tank	combination tank	-	DHW, space heating
   HPS 5		monovalent tank	monovalent tank	-	-
   HPS 5.1		monovalent tank	monovalent tank	DHW, space heating	-
   HPS 6		buffer tank	buffer tank with fresh water station	DHW, space heating	-
   HPS 6.1		solar buffer tank	buffer tank with fresh water station	DHW, space heating	DHW, space heating
   HPS 7		buffer tank	monovalent tank	DHW	-
   HPS 7.1		solar buffer tank	bivalent solar tank	DHW	DHW, space heating
   HPS 8		monovalent tank	buffer tank with fresh water station	DHW, space heating	-

   HPS = heat pump system, DHW = domestic hot water

5. Confirm the selection and close this dialog by clicking on Select.

The page System selection is displayed with the selected system.

Note: when changing the system, the following characteristic values are retained:

• Space Heating
• Domestic hot water
• Heat pump
• Boiler in bivalent systems
• Heat source
• Solar collector

The following characteristic values are not kept:

• Tank, as the tank type depends on the system
