 Outdoor ambient is updated every 5 minutes when operation ON.
 Setting water outlet temperature always follow W
(LO)
or W
(HI)
whenever is higher if outdoor ambient sensor or
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:
o Target water temperature setting:
o Max= 55°C / 60°C* Min= 20°C
* 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”
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:
o Target water temperature setting:
Max = 20°C Min= 5°C
 When buffer tank selection is “YES”
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
 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
