12.1.6.2 Target Zone 2 water temperature setting control
Start condition
- Heating zone 2 is ON by remote control or Timer or Auto Mode OR
- Cooling zone 2 is ON by remote control or Timer or Auto Mode.
Cancel condition
- Heating zone 2 is OFF by remote control or Timer or Auto mode AND
- Cooling zone 2 is OFF by remote control or Timer or Auto mode.
Target Zone 2 water temperature is calculated as below condition.
- Target Zone 2 water temperature = A (Base temperature) + B (shift temperature)
Compensation Direct
A (Base Temperature)
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.
- B (shift temperature) value is depend on the room sensor selection at remote controller as below table:
B (Shift Temp.) B shift value is depend on the room sensor selection at remocon as table below
Sensor Selection
Water temperature B = 0
External Room Thermostat 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°C ; Min: -5°C)
Heat Mode:
B = 0 ; when Zone OFF or Zone Room Thermo OFF
Internal Room Thermostat
&
Room Thermistor
B = follow Heating PI control contents
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.
Maximum/minimum regulation of Target Water Temperature.
Heating Cooling
Max 55°C 20°C
Min 20°C 5°C
Target Zone 2 Water Temperature (Heat mode only) 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”
