o
B (shift temperature) value is depend on the room sensor selection at remote controller as below table:
B (Shift Temp.)
B shift value depend on the room sensor selection at remocon as table below
Sensor selection
Water temperature
B = 0
External Room thermostat
B = 0
Internal Room thermostat &
Room Thermistor
Cool Mode:
B = 0 ; when Zone OFF or Zone Room Thermo OFF
B = 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
Pool Function Selected
B = Delta value setting from remocon
* 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.

* Between outdoor ambient -10°C and -15°C, the water outlet temperature gradually decreases from 60°C to 55°C
Target Zone 2 Water Temperature (Heat mode) during SG ready control
o
If buffer tank selection is “NO” then following shift is carried out.
While digital input is “10” or “11” then,
Final Target Zone 2 water temperature
= Target Zone 2 water temperature* (SG ready % setting (remote control menu))%
o
If buffer tank selection is “YES”
No shift of Target Zone 2 Water Temperature. Target Buffer Tank Temperature will change accordingly.
* Refer to “Buffer tank temperature control”

Final Target Zone 2 water temperature = Target Zone 2 water tempe SG Cool Setting
14.1.6.3 Zone Temperature Control Contents
During Standard System (Optional PCB not connected)
o
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
Thermostat, Water temperature)
o
Target Zone Water Temperature is calculated based on selected temperature control type (Compensation or
Direct) and selected room sensor. Target Water Temperature will set same as Target Zone Water
Temperature
o
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
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)
* 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)
Buffer Tank connection select "NO" &
o
One zone system is select
