21. Force Defrost
Under manual code, user can turn on force defrost through quick menu.
If selection is 'auto', outdoor unit will run defrost operation once if heat pump have
long hour of heating without any defrost operation before at low ambient condition.
(Even auto is selected, user still can turn on force defrost through quick menu)
22. Defrost signal
Defrost signal sharing same terminal as bivalent contact in main board. When defrost signal
set to YES, bivalent connection reset to NO. Only one function can be set between defrost
signal and bivalent.
When defrost signal set to YES, during defrost operation is running at outdoor unit defrost signal
contact turn ON. Defrost signal contact turn OFF after defrost operation end.
(Purpose of this contact output is to stop indoor fan coil or water pump during defrost operation).
23. Pump fl owrate
If pump fl owrate setting is ∆T, unit adjust pump duty to get diff erent of water inlet
and outlet base on setting on * ∆T for heating ON and * ∆T for cooling ON in
operation setup menu during room side operation.
If pump fl owrate setting is set to Max. duty, unit will set the pump duty to the set duty
at *Pump maximum speed in service setup menu during room side operation.
24. DHW defrost
When DHW defrost set to YES, hot water of domestic hot water tank will be used
during defrost cycle.
When DHW defrost set to NO, hot water of fl oor heating circuit will be used during
defrost cycle.
25. Heating control
There are two modes to select for compressor frequency control : Comfort or Effi ciency.
When set to Comfort mode, compressor will run at zone limit maximum frequency
to reach set temperature faster.
When set to Effi ciency mode, compressor will run at part load frequency at initial
stage for energy saving.
26. External meter
There are two systems for generation meter connection : one generation meter system (Heat-
cool meter) or two generation meter system (Heat-cool meter and Tank meter)
Both systems can provide all generation data of heating, cooling and DHW directly from external meter.
If Heat-cool meter is set to Yes, it will read from external meter for heat pump's energy generation data during heating, cooling and DHW operation
If Heat-cool meter is set to No, it will base on unit's calculation for heat pump's energy generation data during heating, cooling and DHW operation.
If Tank meter is set to Yes, it will read from external meter for heat pump's energy generation data during DHW operation
If Elec. meter HP is set to Yes, it will read from external meter for heat pump's energy consumption data.
If Elec. meter HP is set to No, it will base on unit's calculation for heat pump's energy consumption data.
If Elec. meter 1 (PV meter) is set to Yes, it will read from external meter for energy generation data of solar system and display it on Cloud system.
If Elec. meter 2 (Building) is set to Yes, it will read from external meter for energy consumption data of the building and display it on Cloud system.
If Elec. meter 3 (Reserve) is set to Yes, it will read from external meter for energy consumption data obtained from reserved electricity meter and display it on Cloud system.
*1
Set Heat-cool meter to Yes and set Tank meter to No when 1 generation meter system is installed.
Set Heat-cool meter to Yes and set Tank meter to Yes when 2 generation meter system is installed.
Remark : Elec. meter HP refers to Electricity meter that measures Heat Pump unit's consumption.
Elec. meter 1 / 2 / 3 refers to Electricity meter no. 1 / no. 2 / no. 3
