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 Therma 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
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 1 when optional PCB is connected and Zone 1 system is select.

Target Zone 1 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 1 water temperature
= Target Zone 1 water temperature* (SG ready % setting (remote control menu))%
o
If buffer tank selection is “YES”
No shift of Target Zone 1 Water Temperature. Target Buffer Tank Temperature will change accordingly.
* Refer to “Buffer tank temperature control”
Target Zone 1 Water Temperature (Cool mode) during SG ready control

Final Target Zone 1 water temperature = Target Zone 1 water tempe SG Cool Setting
13.1.6.2 Target Zone 2 water temperature setting control
Start condition
o
Heating zone 2 is ON by remote control or Timer or Auto Mode
OR
o
Cooling zone 2 is ON by remote control or Timer or Auto Mode.
Cancel condition
o
Heating zone 2 is OFF by remote control or Timer or Auto mode
AND
o
Cooling zone 2 is OFF by remote control or Timer or Auto mode.
Target Zone 2 water temperature is calculated as below condition.
o
Target Zone 2 water temperature = A (Base temperature) + B (shift temperature)
A (Base Temperature)
Compensation
Direct
Value from the curve + User shift value set
Direct value from user setting
* During heat mode and compensation select, if powerful mode is activated, higher value of WLo or WHi will be use
as curve value.
