12.1.4 Heat + Tank Mode Operation
Setting 1: When Heating priority is set by control panel:
1. 3 ways valve control:
o
3 ways valve switch to room side during External Room Thermo ON OR Solar 3 ways valve ON OR Tank
Thermo OFF time, and switch to tank side at External Room Thermo OFF AND Solar 3 ways valve OFF.
2. Heat pump operation control:-
o
During External Room Thermo ON time : (When room thermo ON, heat pump must operate to room side)

Heat pump operates follow normal operation at room side.
o
During External Room Thermo ON time :

Switch 3 ways valve to tank side, IF
Under Solar Priority Set condition:
o
Tank temperature < Tank THERMO ON TEMP AND Solar Valve OFF
Under Solar Priority Not Set condition:
o
Tan temperature < Tank THERMO ON TEMP

Switch back 3 ways valve to room side, Heat pump and water pump turn OFF, IF
o
External Room Thermo ON back OR
Under Solar Priority Set condition:
 Tank temperature > Tank THERMO OFF TEMP for continuous 10 seconds OR Solar Valve ON.
Under Solar Priority Not Set condition:

Tank temperature > Tank THERMO OFF TEMP for continuous 10 seconds.
* Judge only after heat pump THERMO OFF
* THERMO ON and THERMO OFF point refer to case below.
Operation condition when 3 ways valve switch to tank side:
 Tank water set temperature = tank set temperature or [60°C] whichever lower.
 Heat Pump Water Outlet set temperature is set to [63°C] during tank interval.
 Initial Tank THERMO ON TEMP = heat pump tank target tempe [-8°C].
Tank Thermo ON/OFF Characteristic
o
THERMO OFF TEMP:
1. THERMO OFF TEMP = Heat pump tank target tempe [0°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 OR
3. Tank temperature > Tank set tempe 2°C for continuous 10 seconds, switch 3 ways valve to room
side.
o
Next THERMO ON TEMP:
1. THERMO ON TEMP = Heat pump tank target tempe [2°C] or
2. If tank temperature < THERMO ON TEMP
AND External Room Thermo OFF, switch to tank side.
