Setting 2: When heating priority is not set by remote control:
When Solar Priority is set / not set by remote control:
1 3 ways valve control:
o
3 ways valve switch to room side during heating heat-up interval, and switch to tank side during tank
heat-up interval. Both mode will switch alternatively. Tank mode is the Initial running mode of this heat +
tank mode (heating no priority).
2 Heat pump operation control:
o
During heating heat-up interval
- Follow normal heating operation.
Under solar priority set condition:
- Switch to tank heat-up interval and start counting tank heat-up timer when External Room Thermo
OFF
AND
solar 3WV OFF
AND
Tank temperature < THERMO ON TEMP (End Room Interval
Early)
OR
- Switch to tank heat-up interval and start counting tank heat-up timer when tank temperature <
THERMO ON TEMP
AND
solar 3WV OFF
Under solar priority not set condition:
- Switch to tank heat-up interval and start counting tank heat-up timer when External Room Thermo
OFF
AND
Tank temperature < THERMO ON TEMP (End Room Interval Early)
OR
- Switch to tank heat-up interval and start counting tank heat-up timer when tank temperature <
THERMO ON TEMP
* THERMO ON TEMP is defined form following Case1 to Case4.
o
During tank heat-up interval
- Heat pump tank target temperature = Tank set temperature or [50°C] whichever lower
- Heat pump Water Outlet set temperature is set to Maximum [55°C] during tank interval
- Initial Tank THERMO ON TEMP = heat pump tank target tempe
[-1°C]
Case 1:
- THERMO OFF TEMP:
1.
THERMO OFF TEMP = Heat pump tank target tempe
[+1
°
C]
.
2.
Tank temperature > THERMO OFF TEMP for continuous 10 seconds after heat pump off due to water
thermo, switch 3 ways valve to room side. End Tank heat-up interval and start count heating heat-up
interval.
- THERMO ON TEMP:
1.
THERMO ON TEMP = Heat pump tank target tempe
[-1
°
C]
.
2.
After Heating heat-up interval, always detect tank temperature. Switch to next tank heat-up interval
when tank temperature < THERMO ON TEMP
Case 2:
- Heat pump THERMO OFF TEMP:
1.
Heat pump THERMO OFF TEMP = 53°C +
[+4
°
C]
.
2.
Water outlet temperature > Heat pump THERMO OFF TEMP for continuous 3 minutes, heat pump
OFF.
- THERMO ON TEMP:
1.
THERMO ON TEMP = Water inlet temperature, when heat pump thermo off +
[-3
°
C]
.
Case 3:
- Heat pump THERMO OFF TEMP:
1.
Water inlet temperature > 55°C for continuous 60 secs, heat pump OFF.
- THERMO ON TEMP:
1.
THERMO ON TEMP = Water inlet temperature < 55°C.
Case 4 (Only during solar priority is set condition):
When solar pump ON, tank heat-up interval end early and 3 ways valve switch to room side.
- THERMO ON TEMP:
1.
THERMO ON TEMP = Heat pump tank target tempe
[-1
°
C]
.
2.
After Heating heat-up interval, always detect tank temperature. Switch to next tank heat-up interval
when tank temperature < THERMO ON TEMP and solar 3 way valve OFF.
