14.1.6.2 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.
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 Temperatu
e PI control logic
Pool Function Selected B = Delta value setting from
emocon
* 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.
Heating Cooling
Max 55°C / 60°C* 20°C
Min 20°C 5°C
* 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”
Target Zone 2 Water Temperature (Cool mode) during SG ready control
o Final Target Zone 2 water temperature = Target Zone 2 water temperature + SG Cool Setting
