Case 2:
o
Heat pump THERMO OFF TEMP:
1.
Heat pump THERMO OFF TEMP = 63°C +
[+4
°
C]
.
2.
Water outlet temperature > Heat pump THERMO OFF TEMP for continuous 3 minutes, heat pump
OFF.
o
Next THERMO ON TEMP:
1.
THERMO ON TEMP = Water inlet when heat pump THERMO OFF +
[-3
°
C]
.
2.
If water outlet temperature < THERMO ON TEMP
AND
External Room Thermo OFF, heat pump ON.
Case 3:
o
Heat pump THERMO OFF TEMP:
1.
Water inlet temperature > 65°C for continuous 60 secs, heat pump OFF.
o
Next THERMO ON TEMP:
1.
THERMO ON TEMP = Water inlet temperature < 65°C.
2.
If water inlet temperature < THERMO ON TEMP AND External Room Thermo OFF, heat pump ON.
Case 4: (Only during solar priority is set condition)
o
When solar request ON, solar valve will ON and switch 3 ways valve to room side
o
THERMO ON TEMP:
1.
THERMO ON TEMP = Heat pump tank target tempe
[-2
°
C]
.
2.
If tank temperature < THERMO ON TEMP AND External Room Thermo OFF
AND
Solar 3WV OFF,
switch to tank side.
3 Backup Heater control:-
o
During External Room Thermo ON time, follow normal backup heater control operation
o
During External Room Thermo OFF time, Backup heater OFF
4 Booster heater control:
o
Booster heater On/Off follow normal operation.
* Under solar priority is set condition, when solar 3 way valve is ON, booster heater turn OFF.
5 Solar 3 way valve:
o
Solar 3 way valve operates follow solar operation specification.
* Under solar priority is set condition, when solar 3WV turn ON, booster heater will turn OFF and 3 ways
valve switch to room side.
* Under solar priority is not set condition, solar 3WV will OFF when heat pump operate to tank side.
o
2 way valve opens.
Setting 2: When heating priority is not set by control panel:
When Solar Priority is set / not set by control panel:
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 after room heat-up timer complete
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
