B (shift temperature) value is depend on the room sensor selection at remote controller as below table:
o
B (Shift Temp.)
Water temperature
External Room thermostat
Internal Room Thermostat &
Room Thermistor
Pool Function Selected
* B = 0 regardless of which sensor selection, if SHP control bit is enable except Pool function select (maintain Pool
"B" value)
** Pool function also can be select at Zone 2 when optional PCB is connected and Zone 2 system is select.

Maximum/minimum regulation of Target Water Temperature.
* 1 Between outdoor ambient -15°C and -20°C, the water outlet temperature gradually decreases from 60°C to 55°C.
1
* Between outdoor ambient 5°C and 0°C, the water outlet temperature gradually decreases from 65°C to 60°C.
* 1 Between outdoor ambient 20°C and 25°C, the water outlet temperature gradually decreases from 65°C to 60°C.
2
* Only when ΔT is set to 15°C, the set temperature above 60°C will take effect.

Target Zone 2 Water Temperature (Heat mode) during SG ready control
If buffer tank selection is "NO" then following shift is carried out.
o
 While digital input is "10" or "11" then,
Final Target Zone 2 water temperature
= Target Zone 1 water temperature* (SG ready % setting (remote control menu))%
If buffer tank selection is "YES"
o
 No shift of Target Zone 2 Water Temperature. Target Buffer Tank Temperature will change accordingly.
* Refer to "Buffer tank temperature control"

Target Zone 2 Water Temperature (Cool mode) during SG ready control
Final Target Zone 2 water temperature = Target Zone 2 water temperature + SG Cool Setting
o
13.1.6.3 Zone Temperature Control Contents

During Standard System (Optional PCB not connected)
Only 1 zone temperature control is available
o
This zone room temperature is control by either one of the 4 room sensor (Room Th, Int/Ext Room
o
Thermostat, Water temperature)
Target Zone Water Temperature is calculated based on selected temperature control type (Compensation or
o
Direct) and selected room sensor. Target Water Temperature will set same as Target Zone Water
Temperature
Target Water Temperature is the temperature for heat pump to operate refer to indoor water outlet sensor.
o
Heat pump and water pump OFF when ROOM Thermo OFF (Zone thermo OFF by Room Th or Room
o
Thermostat).
* There will be no zone sensor connected to zone 1 (No zone sensor error), mixing valve and zone pump will not
operate.

During Extension System (Optional PCB connected)
B shift value depend on the room sensor selection at remocon as table below
Sensor selection
B = 0
B = 0
Cool Mode:
B = 0 ; when Zone OFF or Zone Room Thermo OFF
B = 1* (room set temp (R/C) - actual room temp)
Max/Min Regulation of B: (Max = 5 ; Min = -5)
Heat Mode:
B = 0 ; when Zone OFF or Zone Room Thermo OFF
B = follow Heating Room Temperature PI control logic
B = Delta value setting from remocon
