14.1.6 Target Zone Water Temperature Control
Purpose:- To control zone mixing and zone pump according to the zone sensor temperature
14.1.6.1 Target Zone 1 water temperature setting control

Start condition
Heating zone 1 is ON by remote control or Timer or Auto Mode OR
o
Cooling zone 1 is ON by remote control or Timer or Auto Mode.
o

Cancel condition
Heating zone 1 is OFF by remote control or Timer or Auto mode AND
o
Cooling zone 1 is OFF by remote control or Timer or Auto mode.
o

Target Zone 1 water temperature is calculated as below condition.
Target Zone 1 water temperature = A (Base temperature) + B (shift temperature)
o
A (Base Temperature)
* During heat mode and compensation select, if powerful mode is activated, higher value of WLo or WHi will be use
as curve value.
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 1 when optional PCB is connected and Zone 1 system is select.
 Maximum/minimum regulation of Target Water Temperature.
Max
Min
* Between outdoor ambient -10°C and -15°C, the water outlet temperature gradually decreases from 60°C to 55°C

Target Zone 1 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 1 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 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 temperature + SG Cool Setting
o
Compensation
Value from the curve + User shift value set
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 = 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
