Press the ⚙ button, press the ∧, ∨ or ⟨,⟩ button to select Priority A2A, and then press the OK button. Setting FSV #5033 to '0' becomes 'Priority A2A', and setting to '1' becomes 'Priority DHW'.

• Under the installation of both A2A (Air-To-Air type air conditioner) and A2W (Air-To-Water type hydro unit) at the same time, our outdoor machine can supply its full capacity to the operating indoor machines (including A2A or A2W). If there are simultaneous operating demands from many A2A machines with A2W, the priority of controlling the outdoor machine (ex: compressor frequency) will be given to A2A, because of their fast response for use's comfort. Only the remaining capacity of outdoor machine will be given to A2W during A2A's normal operation. In this case, it might take very long time for A2W heating, so the outdoor machine will alternate the controlling priorities between A2A and A2W with time basis.
• Priority maximum operation time (at FSV #5033=0): FSV #5031 (Default 30 min., Range 10 \~ 90 min.), After elapsing A2A maximum time, the outdoor machine will operate only for A2W to speed up the A2W's heating/cooling performance, even though there are A2A's continuous operation demands.
• Non priority minimum operation time (at FSV #5033=0): FSV #5032(Default 5 min., Range 3 \~ 60 min.), in this minimum time, the outdoor machine will operate only for A2W, even though there are no more A2W's continuous operation demands.

※ A2A : Air to Air, A2W : Air to Water
- When DHW Priority is enabled, hot water (heating) operation is given priority only if the A2A & A2W simultaneous operation is on. Other operations are the same as when A2A Priority is enabled.

CAUTION

• While A2W is in operation, A2A does not operate. This is a normal operation.
• While A2A or A2W is not in simultaneous operation, you can use any mode without operation mode restriction.

- Do not set WL1 below 16 degrees to prevent floor condensation when using underfloor cooling.

External Room Thermostat (Field Option)

• Terminal #1 (#2091, Default 0 for no usage), #2 (#2092, Default 0 for no usage)

• To use wired remote controller for heating/cooling operation, both of the above settings should be set to 0 simultaneously. If not, thermostat controls system.
• To use the External Room Thermostat option, set the 2-zone control option (FSV #4061) to "0" for disabling it.
• If set to #2091/#2092 1, the compressor can be turned on or off only by the thermostat.
• If set to #2091/#2092 2\~4, the compressor can be turned on or off by the thermostat or according to the WL discharged water temperature.(#2092 2, WL Thermo off → Water pump off, #2092 3, WL Thermo off → Water pump on, #2092 4, WL Thermo off → Water pump 7min off → 3min on →......).

Heat Pump Variables for Space Heating

• FSV #4011 for DHW priority is set to "0(DHW)" (Default) as a default. Space heating gets a priority by setting FSV #4011 "1", but this is only valid when the outdoor temperature is lower than the specified temperature defined by FSV #4012.
• When priority is on DHW, DHW mode (FSV #3025,default 30 mins) and space heating (FSV#3026,default 180 mins) alternately operate, and when priority is on space heating, they operate as space heating mode.
• Space heating off temperature(FSV #4013, Default "35/45°C", Range 10 \~ 35/45°C): At high outdoor temperature above this value, the space heating will be turned off, to avoid overheating.

Backup Heater Variables for Space Heating

• The FSV #4021 should be set to 1(Yes) to use 2-stage electric backup heater in hydro unit as an additional heat source. (If FSV # 4021 is 2, a 1-stage electric backup heater is used)
  • To configure the backup heater's operating conditions by setting FSV #4023 and FSV #4024.
• When FSV #4023 is set to 0, the backup heater operates regardless of the outdoor temperature.
• When FSV #4023 is set to 1(Default), the backup heater operates when the outdoor temperature is below FSV #4024(Default "0") to save energy; its operation is restricted at FSV #4024 or higher.
• The FSV #4022 for backup heater priority should be set to "0 (both)" (Default) or "1" (backup) to use backup heater. If not (booster heater priority), the backup heater can be operated in case of no booster heater demand.
• The threshold temperature for backup heater operation during defrost mode to prevent cold draft because of chilled water can be controlled by adjusting FSV #4025. Under FSV #4025 of water outlet temperature, backup heater Will be turned on.

NOTE

- To use both backup heater and booster heater together at the same time as set FSV#4022="0", please check the capacity of the power circuit breaker of your house before use.

External Backup Boiler for Space Heating (Field Option)

• The FSV #4031 should be set to "1 (Yes)" to use a backup boiler as an additional heat source. (default: "0 (No installation)")
• Priority of backup boiler and heat pump is defined by FSV #4032 (default: "O (OFF)")
• To compensate the lowered heat pump heating performance under very cold weather conditions, the backup boiler operates instead of heat pump under the threshold temperature (FSV #4033, Default "-15°C", Range -20 \~ 5°C).

Mixing valve Installation (Field Option)

- The FSV #4041 should be set to "1 or 2" to use mixing valve.

※ 4041 = 1 : Controlled based on the temperature difference (4042, 4043)

※ 4041 =2 : Controlled based on the temperature difference of the WL value

ex) Heating <#4041=1> <#4041=2>

• FSV #4042 / #4043 is for adjusting temperature difference between Tw3 (Tw2) and Tw4.
• FSV #4044 determines the mount of the opening/closing degree of the valve per operation, and the larger the set number, the greater the opening/closing degree per operation. It operates every FSV#4045 set interval.
• When using mixing valve, FSV #4046 should be matched with mixing valve running time characteristic.

Inverter Pump Installation (Field Option)

• FSV #4051=1 (Default) : Inverter pump use + Output 100%, FSV #4051=2 : Inverter pump use + Output 70%, FSV #4051=0 : Inverter pump Not use.
• FSV #4052 is for adjusting temperature difference between Tw2 and Tw1.
• FSV #4053 determines the amount of change in PWM output during pump operation, and the larger the set value, the greater the change in PWM output per operation.
• Pump PWM minimum output is limited to 25% to 55% according to FSV #4054. (Setting "0":25%, "1":35%, "2":45%, "3":55%)

NOTE

- Tw1 (Inlet Water Temp), Tw2 (Discharge Water Temp), Tw3 (Backup Heater outlet Water Temp), Tw4 (Mixing valve Temp.)

Zone Control (Field Option)

- Zone control Using Wired Remote Control (install option) FSV # 4061 should be set to "1 (Yes)" to zone control.

• To use the zone control (FSV #4016=1), set the thermostat control option (FSV #2091 & #2092) to "0" for disabling it.
• This field option controls each zone (Zone 1, Zone 2) with a wired remote controller setting not by using the external room thermostat signal.
• According to FSV #4062/4063 setting, Pump (2way V/v) is operated when Zone1/ Zone2 Thermo Off (Setting "0": Thermo off_ Water pump off, "1": Thermo off _ Water pump on, "2": Thermo off _ Water pump 7min off → 3min on →......).

Outing Mode

- All the target temperatures – space heating and cooling, water law, DHW, Room temperature – are set to the values defined in the above table under the holiday mode.

NOTE

- With the lowered target temperatures (FSV #5011 \~ #5019), the system operates normally.

- DHW heating only by the heat pump to save energy (Operated in Eco mode of wired remote control) Target DHW temperature is lower than the temperature set by user. The temperature difference is defined by FSV #5021. (default: 5°C) If user sets the temperature 45°C, the system sets the target temperature 40°C with the default setting.

• If user want additional energy saving, use a "Saving mode" (#5022, default: 0, OFF)
  – The user can set the "Thermo On" temperature during "Saving mode" using FSV #5023

Peak Power Control

• If users make contracts with local electric power company for limiting the amount of power consumption when a surge in power usage, users can set FSV of "Forced off".
• According to FSV (#5041), Default is Non-usage. And According to FSV (#5042), If input is "0 (default)", Back up heater (BUH) is unavailable while external contact is high.
  If input is "1", Only Compressor(Heat Pump) is available.
  If input is "2", Only Booster Heater (BSH) is available.
  If input is "3", nothing is available.

[D-00] Compressor Back up heater Booster heater
0 (Default) Permitted Forced off Permitted
1 Permitted Forced off Forced off
2 Forced off Forced off Permitted
3 Forced off Forced off Forced off

• Applying the control when power voltage of input contact is high is default. According to FSV (#5043), it is available to adopt this logic in low condition exceptionally.
• When Peak power control is applied, the system is subject to "Forced OFF" according to the set value. Therefore, appropriate measures such as antifreeze are necessary to prevent freezing at low temperatures.

FR Control(Frequency ratio control) - Display "DR" on wired remote control

- This is to limit the maximum frequency of the outdoor unit compressor. (if #5051 = 1 "use")

- Mothod1: External DC signal Control uses a DC voltage of 0 \~ 10V (0v = 50%, \~ 10v = 150%)

- Mothod 2: Demand ratio (DR) control through Modbus communication.

Outdoor Unit Control

• Minimum Thermo ON operating time limit (FSV#6022): Minimum operating time after outdoor unit starts.
- Heating Optional Thermo On/Off Function (FSV#6031): Function to induce an increase in efficiency during operation by stopping the outdoor unit when the outdoor unit is continuously operated at a low operating frequency during heating operation.

Thermostat Control Type (FSV #6041)

- When external room thermostat setting (FSV #2091, #2092) is set to use, it is applied as follows.

FSV #6041 Type Output when all thermostat contact is OFF
0 2way valve Control		Open
1	Secondary Pump Control	OFF

- When external room thermostat setting (FSV #2091, #2092), 2Zone Control (FSV #4061) are set to unuse, it is applied as follows.

FSV #6041	DWH mode	Not DWH mode
0	Close	Open
1	Close Open for Thermo ON, Close for Thermo Off

PV Control (Photovoltaics control)

This is for energy saving by using the solar energy.

The FSV #5081 should be set to "1(Yes)" for PV control. (However, Peak power control can not be used at the same time.)

FSV 0 1
#5081 Disable (Default) Activation

NOTE

- Except for how water mode, This function is activated only for the outing mode.

• Cooling mode (FSV #5082 = 2°C, Default)

• Room sensor setting: Current setting value - FSV #5082 (Min = FSV #1022)
• Water outlet setting: Current setting value - FSV #5082 (Min = FSV #1012)
• Water law setting: Current setting value - FSV #5082 (Min = FSV #2061, #2062, #2071, #2072)

- Heating mode (FSV #5083 = 2°C, Default)

• Room sensor setting: Current setting value + FSV #5083 (Max = FSV #1041)
• Water outlet setting: Current setting value + FSV #5083 (Max = FSV #1031)
• Water law setting: Current setting value + FSV #5083 (Max = FSV #2021, #2022, #2031, #2032)

- Hot water mode

- Thermo on operation regardless of outing mode: Setting temperature = Max temperature of hot water mode (FSV #1051)

Smart Grid Control

The FSV #5091 should be set to "1(Yes)" for Smart Grid control.

FSV 0 1
#5091 Disable (Default) Activation

Operation mode for Smart Grid

Operation Mode Terminal	1 Terminal 2
Mode 1 Short Open
Mode 2 Open Open
Mode 3 Open Short
Mode 4 Short Short

• Mode 1: Forced thermo off operation of all system
• Mode 2: Normal operation It is equally applied both heating and hot water mode.

- Mode 3: Normal operation (FSV #5092 = 2°C, FSV #5093 = 5°C, Default) The heating and hot water setting temperature are set by the FSV setting value.

• Heating mode (Room sensor setting) : Current setting value + FSV #5092
• Heating mode (Water outlet setting) : Current setting value + FSV #5092
• Heating mode (Water law setting) : Current setting value + FSV #5092
• Hot water mode : Current setting value + FSV #5093

- Mode 4: When operating on, the setting temperature is reflected as follows.

Hot water mode

• 5094=0 : Target setting temperature is 55/63/70°C. FSV#3021 (Maximum DHW tank temperature with the heat pump operation)

• 5094=1 : Target setting temperature is 70°C.

  [If FSV #3031 is 0 (no use booster heater) or DHW mode is economic mode, it does not activate booster heater.]

Heating mode

• Heating mode (Room sensor setting) : Current setting value + FSV #5092+3°C (Max=FSV #1041)
• Heating mode (Water outlet setting): Current setting value + FSV #5092+5°C (Max=FSV #1031)
• Heating mode (Water law setting): Current setting value + FSV #5092+5°C
