TDM (Time-Division Multi) Variables (TDM product Only)

• 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.

FSV setting	A2A Cooling + A2W Cooling	A2A Cooling + A2W Heating	A2A Heating + A2W Cooling	A2A Heating + A2W Heating
A2A Priority(#5033=0)	A2A CoolingA2W Cooling"Same cooling Mode TDS Control"	A2A CoolingA2W Cycle Off (The heater just operates without heating.) "Cooling Operation"	A2A HeatingA2W x (Not operation)"Heating Operation"	A2A HeatingA2W Heating"Same heating Mode TDS Control"
DHW Priority(#5033=1)	Same with A2A Priority setting	A2W HeatingA2A Cooling"(Heating + Cooling)TDS Control"	Same with A2A Priority setting	Same with A2A Priority setting

※ 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.

- Type of water law for according to cooling devices(floor/FCU): #2081(Default "1"(WL1 for floor), "2"(WL2 for FCU or radiator)

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.
• 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 →......).

20922, #20923, #20924,

• Types of water law used by room thermostat operation will follow the FSV settings defined in #2041 (heating) and #2081 (cooling) respectively.

• During the thermostat operation, the user has the possibility to shift up or down the target water temperature within the range of -5 +5^ .

• When the remote controller is used, floor valve should be connected to zone #1 and the FCU valve should be separately connected to zone #2 of the Hydro Unit PBA.

• When only floor cooling/heating is installed and if the Water Law or outlet water temperature is too low, 2way valve may closed and E911 error may occur.
• When the floor and FCU units are installed together and operating in cooling mode, floor valve may close and E911 may occur to prevent floor condensation when the outlet water temperature is below 16°C. Therefore FCU should secure minimum value for the flow rate.
• Thermostat #2 which controls FCU has the priority for operation modes and the discharge water temperature.
• Samsung is not responsible for the accidents such as floor condensations which can occur by not connecting the valve to the zone #1 port of the Hydro Unit PBA.

DHW Application

The FSV #3011 in the wired remote controller should be set to "1 or 2" to use DHW function.

If FSV #3011 is set to 1, the DHW operation starts based on the thermo on temperature. If FSV #3011 is set to 2, the DHW operation starts based on the thermo off temperature.

(For example, when the current temperature becomes 45^ C under the conditions that the thermo on temperature is 43^ C and the thermo off temperature is 48^ C, the DHW turns off if FSV #3011 is set to 1 and DHW turns on if FSV #3011 is set to 2.)

Heat Pump Variables for Controlling DHW Tank

• Maximum DHW tank temperature with R-410A(refrigerant) heat pump operation : FSV #3021, Default 50°C, Range : 45 \~ 50°C.
• Temperature difference determining the heat pump OFF temperature : FSV #3022, Default 2°C, Range : 0 \~ 10°C.
• Temperature difference determining the heat pump ON temperature : FSV #3023, Default 5°C, Range : 5 \~ 20°C.

• DHW heating mode timer : Mode timer manage the operation terms when there are simultaneous requests of space heating/cooling and DHW.

• FSV #3024 (minimum Space heating operating time, Default 5 min., Range 1 \~ 20 min.), #3025 (maximum DHW time, Default 30 min., Range 5 \~ 95 min.), #3026 (maximum space heating operation time, Default 3 hour, Range 0.5 \~ 10 hour)
  – Maximum operation time is applied only when both DHW and Space heating request operation. DHW or Space heating operates continuously until reaching at target temperature without time limitation in the single operation.

NOTE

- The FSV #4011 for DHW priority should be set to "0(DHW)("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.

Booster Heater Variables for Controlling DHW Tank

• The FSV #3031 should be set to "1(On)" (Default) to use booster heater as an additional heat source for DHW tank.

• Booster heater startup delay timer : In case of DHW request, this timer will delay the operation of booster heater compared to heat pump.

• FSV #3032 (Default 20 min., Range 20 \~ 95 min.), In "Power" DHW mode, the delay timer will be neglected, and the booster starts immediately.

• In "Economic" DHW mode, the DHW heating will be conducted only with heat pump.

• 3032 should be smaller than the maximum H/P time (#3025). If the delay time is set too high, it might take very long time for DHW heating.

• Temperature difference determining the booster heater OFF temperature (T_BH OFF = Tu + #3033): FSV #3033, Default 0°C, Range: 0 \~ 4°C.

• Temperature difference determining the booster heater ON temperature (T_BH ON = T_BH OFF - 2)

NOTE

• The FSV #4022 for booster heater priority should be set to "0 (both)" (Default) or "2" (booster) to use booster heater.
• If not (backup heater priority), the booster heater can be operated in case of no backup heater demand.

Disinfection Function

- The FSV #3041 should be set to "1 (On)" (Default) to use disinfection function.

- Scheduling : Day (#3042, Default "Friday"), starting time (#3043, Default "23:00"), target tank temp. (#3044, Default "70°C"), duration (#3045, Default 10 min.)

NOTE

• Disinfection function is available only when a booster heater is connected.
• Check tank capacity, booster heater capacity, and booster heater for issues if disinfection operation does not work normally over the maximum operation time(E919 error).

Forced DHW by User's Input

• Forced DHW mode can be activated by changing setting value from the default setting (#3011, "0" (No)).
• Forced DHW mode shall be working depending on Timer setting (#3051, #3052).

Additional Solar panel/DHW thermostat Installation for DHW with Heat Pump (Field Option)

• Solar panel and heat pump are able to operate simultaneously by default setting value. (FSV #3061, "1")
• When using DHW thermostat, set the FSV #3061, "2".
• Zone #1 and #2 valve always keep open except DHW mode in "ON" when the power is "ON" unless changing the FSV #3071. Default: Room direction valves are open and DHW valve is closed.
• Zone #1 and #2 can be open separately or simultaneously but all three zone valves can not be open or closed at the same time.
• There is one minute delay of 2-way / 3-Way valve closing whereas no delay of valve opening.

Heat Pump Variables for Space Heating

• FSV #4011 for DHW priority is set to "O(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.
• Cold weather compensation is applied when the space heating gets a priority (FSV #4011=1). It is due to position of heating coil and booster heater in the water tank. Heating coil is at the bottom part of the water tank and the booster heater is located at the middle part of the tank. So the heating coil is efficient to heat the whole water in the tank. Chances that hot water flows through the heating coil decrease with the space heating priority. And lower part of water in the tank might not get enough heat with the booster heater.
• Space heating off temperature(FSV #4013, Default "35°C", Range 14 \~ 35°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.
• To compensate the lowered heat pump heating performance under very cold weather conditions, the FSV #4023 should be set to "1(On)" (Default).

- The threshold temperature to use backup heater for cold weather compensation: FSV #4024, Default "0°C", Range -25 \~ 35°C

- The backup heater operation is restricted to save energy in the threshold temperature range.

• 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 heaters together at the same time, 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: "0 (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 vavle 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.
• 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.

NOTE

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