12.1.5 Tank Mode Operation
Control contents:
3 ways valve direction
- 3 ways valve switch and fix to tank side.
Heat pump Thermostat characteristic
- Water set temperature = Tank set temperature or
[51°C]
whichever lower.
- Heat pump Water Outlet set temperature is set to Maximum (53°C) at tank mode.
i. Case 1
- THERMO OFF TEMP:
1 THERMO OFF TEMP = Water set tempe
[0°C]
.
2 Tank temperature > THERMO OFF TEMP for continuous 10 seconds after heat pump OFF, water pump OFF.
- THERMO ON TEMP:
1 THERMO ON TEMP = Water set tempe
[-2°C]
.
When detect tank temperature < THERMO ON TEMP, water pump ON for 3 minutes then heat pump ON.
ii. Case 2
- Heatpump THERMO OFF TEMP:
1 Heat pump THERMO OFF TEMP = 55°C +
[+2°C]
.
2 Water outlet temperature > Heat pump THERMO OFF TEMP for continuous 3 minutes, heat pump OFF.
- Heatpump THERMO ON TEMP:
1 Heat pump THERMO ON TEMP = Water inlet during thermo off time +
[-3°C]
.
2 Heat pump ON back when water outlet temperature < Heat pump THERMO ON TEMP.
iii. Case 3
- Heat pump THERMO OFF TEMP:
1 Water inlet temperature > 55°C for continuous 60 secs, heat pump OFF.
- Heat pump THERMO ON TEMP:
1 Heat pump THERMO ON TEMP = Water inlet temperature < 55°C.
Booster heater control
- Booster heater turn On and Off follow normal operation.
- Booster heater turn ON condition:
1 During startup time (initialization), Booster heater turn ON after DELAY TIMER.
2 When tank temperature lower than HEATER ON TEMP
3 20 minutes from previous heater off.
- Booster heater turn OFF condition:
1 When tank temperature higher than tank set temperature for continuous 15 secs.
Solar 3 way valve
- Solar pump operates follow solar operation specification.
2 way valve closes
Others
- Indoor backup heater cannot be ON during tank mode only.
