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