If Buffer selection is “NO”
Room side
New Target Zone Water Temperature = Current Target Zone Water Temperature * Remote Control Setting
(*Capacity 1) %
(Zone 1 and Zone 2 will change according to its own target zone water temperature.)
(Max regulation depend on the temperature control type select)
DHW Tank side
New Tank Set Temperature = Tank Set Temperature * Remote Control setting for DHW ("Capacity 1) %
* (Max regulation depends on the tank max setting limit)
Setting temperature for cooling is changed.
New Target Water Temperature = Target Water Tempe Remote Control setting for cool (*Capacity 1)
* (Min/Max regulation of cooling water set apply)
While digital input is detected " 11 " (Capacity 2)
o
Setting temperature for heating and Tank is changed.
However, which setting temperature is change depend on system setting.
If Buffer selection is “YES”
Room side
New Target Buffer tank temperature = Current Target Buffer Tank Temperature * Remote Control setting
(" capacity 2) %
* Max Min regulation is follow Target Buffer tank temperature control specification
** No change of Target zone water temperature, only set higher buffer tank temperature.
DHW Tank side
New Tank Set Temperature = Tank Set Temperature * Remote Control setting for DHW ("Capacity 2) %
* (Max regulation depends on the tank max setting limit)
If Buffer selection is “NO”
Room side
New Target Zone Water Temperature = Current Target Zone Water Temperature * Remote Control Setting
(*Capacity 2) %
(Zone 1 and Zone 2 will change according to it's own target zone water temperature.)
(Max regulation depend on the temperature control type select)
DHW Tank side
New Tank Set Temperature = Tank Set Temperature * Remote Control setting for DHW ("Capacity 2) %
* (Max regulation depends on the tank max setting limit)
** This function is not applicable for Cooling mode.
Setting temperature for cooling is changed.
New Target Water Temperature = Target Water Tempe Remote Control setting for cool (*Capacity 2)

14.29 Demand Control (Optional PCB)
Remote control setting:
When Optional PCB connection select 'YES", Demand Control function can select "YES" or "NO".
Purpose:
After the demand control select YES, below control will activated.
o
0-10V Demand control
0-10V Demand control
Demand control is use to reduce the current usage of heat pump unit by third party device.
Control start condition:
Select “YES” at Demand control at installer menu.
0-10V input for this electrical current control is detected.
Control content:
If start condition is fulfilled, indoor will receive the voltage signal from optional PCB. Indoor will send the rate
value to outdoor unit.
Outdoor will change the current limit according to the percentage receive from indoor unit.
