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
o
Cooling zone 2 is ON by remote control or Timer or Auto Mode.
o

Cancel condition
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.
o

Target Zone 2 water temperature is calculated as below condition.
Target Zone 2 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 2 when optional PCB is connected and Zone 2 system is select.
 Maximum/minimum regulation of Target Water Temperature.
Max
Min
 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"
12.1.6.3 Zone Temperature Control Contents

During Standard System (Optional PCB not connected)
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
o
Thermostat, Water temperature)
Target Zone Water Temperature is calculated based on selected temperature control type (Compensation or
o
Direct) and selected room sensor. Target Water Temperature will set same as Target Zone Water
Temperature
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
o
Thermostat).
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
