
Outdoor ambient is updated every 5 minutes when operation ON.

Setting water outlet temperature always follow W
indoor communication error happen.
However, when powerful mode is requested by remote control during heating mode, the higher value of HLo or Whi
will be used for A calculation.
* There are 2 compensation curves (for heating and cooling). During heating mode, the heating curve is used and
during cooling mode, the cooling curve is use.

Compensation curve set shift value:
14.1.5 Target Water Temperature at Extension System (Optional PCB is connected)
Target water temperature is calculated as below.

Heat Mode:
Target water temperature setting:
o
Max= 55°C / 60°C*
o
* Between outdoor ambient -10°C and -15°C, the water outlet temperature gradually decreases from 60°C to 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:
o
Max = 20°C Min= 5°C

When buffer tank selection is "YES"
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

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
