12.1.5 Target Water Temperature at Extension System (Optional PCB is connected)
Target water temperature is calculated as below.

Heat Mode:
Target water temperature setting:
-
Max= 55°C
When buffer tank selection is "YES:"
-
Target water temperature = Target buffer tank temperature + [2°C]
When buffer tank selection is "NO"
-
If both zone 1 and zone 2 is active
o
Target Water Temperature = Higher zone target water temperature of Zone 1 and Zone 2.
If only one zone is active
o
Target Water Temperature = Zone target water temperature of active zone.

Cool mode:
Target water temperature setting:
-
Max = 20°C
When buffer tank selection is "YES"
-
If both zone 1 and zone 2 is active
o
Target Water Temperature = Lower Zone Target Water Temperature of Zone 1 and Zone 2 + [-3°C]
If only one zone is active
o
Target Water Temperature = Zone Target Water Temperature of active zone + [-3°C]
When buffer tank selection is "NO"
-
If both zone 1 and zone 2 active
o
Target Water Temperature = Lower Zone Target Water Temperature of Zone 1 and Zone 2
If only one zone is active
o
Target Water Temperature = Zone Target Water Temperature of active zone
*Cool Mode does not have SG ready control
