13.17 SMART DHW mode
Panasonic All In One model provide the option to choose STANDARD DHW Mode or SMART DHW Mode for Tank
Heat Up according to requirement. SMART DHW mode comparatively consume lower tank heat up power but longer
re-heat time than STANDARD DHW Mode.
SMART DHW control
During SMART DHW start time 20:00 (Default Setting) to SMART DHW stop time 05:00 (Default setting)
Heat pump re-heat the tank water only when tank temperature drop below 20°C (Default setting)
Time between 05:00 to 20:00
Heat pump reheat the tank water when tank temperature as below condition
Condition 1: Tank Heater ON
Reheat when tank temperature below tank set tempe R/C (Tank re-heat Temperature) - 3°C
Condition 2: Tank Heater OFF
Reheat when tank temperature below Tank set temperature or tank limit temperature (Whichever lower) + R/C (Tank
re-heat Temperature) -3°C
* SMART DHW start time, stop time and SMART ON Temperature can change in CUSTOM menu.
STANDARD DHW Mode
Heat pump always reheat the tank water when tank temperature as below condition
Condition 1: Tank Heater ON
Reheat when tank temperature below tank set tempe R/C (Tank re-heat temperature)
Condition 2: Tank Heater OFF
Reheat when tank temperature below Tank set temperature or tank limit temperature (Whichever lower) + R/C (Tank

13.18 DHW Capacity Setting
DHW Capacity is heat pump heating capacity output control during tank boiling operation. There are two DHW
capacity setting (VARIABLE & STANDARD) which can be set in remote control.
VARIABLE DHW Capacity:
Heat pump operate with efficient (Low) Capacity to boil tank temperature during re-heat process. And heat pump
regulated to operate with high capacity to boil tank temperature when tank temperature drop below 25°C.
STANDARD DHW Capacity:
Heat pump operate according to outdoor rated heating capacity during tank boiling process.
