• 2021 and 2022 values influence each other.

Because 2021 is the Max. Value and 2022 is the Min. Value.

So the 2022 value cannot be set higher than the 2021 value, and the 2021 value cannot be set lower than the 2022 value. The same applies to 2031 and 2032.

• 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°C .
• 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.

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

Disinfection function can be performed only with Samsung's DHW tank installation.

Urgent DHW by User's Input (Hot Key of Wired Remote Controller)

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

Additional Solar Panel 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" (Yes)) • Solar panel gets a priority by setting "0" in FSV #3061.
• Zone #1 and #2 valves 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 opened separately or simultaneously, but all three zone valves cannot be opened or closed at the same time. There is a one-minute delay for the 2-way valve closing, whereas there is no delay for valve opening. Individual zone control is only available with an external thermostat.

Heat Pump Variables for Space Heating

• FSV #4011 for DHW priority is set to "0 (DHW)" (Default) as a default. Space heating gets priority by setting FSV #4011 to "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 space heating gets priority (FSV #4011=1). This is due to the position of the heating coil and booster heater in the water tank. The 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 space heating priority. And the lower part of water in the tank might not get enough heat with the booster heater. Cold weather compensation raises the booster heater target temperature by the temperature of FSV #3034 (default=10°C) higher than the user setting.
• 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.
• Overshoot temperature (FSV #4014, Default "2°C", Range 1~4°C): N/A yet

Backup Heater Variables for Space Heating

• The FSV #4021 should be set to "1 (On)" to use the 2-stage electric backup heater in the hydro unit as an additional heat source.
• To compensate for 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 the backup heater for cold weather compensation: FSV #4024, Default "0°C", Range -15~35°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 the 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, the backup heater will be turned on.

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).

Outing Mode (Hot Key of Wired Remote Controller)

- 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 (outing hot key)

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

- DHW heating only by the heat pump to save energy. 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.

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 "O(default)", all the thermal applications are unavailable while external contacts is high. If input is "1", Only the booster heater is available. If input is "2", Only the back up heater is available.
• Applying the control when the power voltage of the input contact is high is the default. According to FSV (#5043), it is available to adopt this logic in low condition exceptionally.
• When applying this logic, the SAMSUNG controller will get "Thermo off" condition for all operations.
• If not used for a long time, anti-freeze fluid shall be used to prevent damage to the unit in cold conditions.

Maintenance activities

- In order to ensure optimal availability of the unit, a number of checks and inspections on the unit and the field wiring have to be carried out at regular intervals, preferably yearly. This maintenance should be carried out by a SAMSUNG local technician. Besides keeping the remote controller clean by means of a soft damp cloth, no maintenance is required by the operator.

During longer periods of standstill, e.g. during summer with a heating only application, it is very important NOT TO SWITCH OFF THE POWER SUPPLY towards the unit.

Switching off the power supply stops the automatic repetitive movement of the motor in order to prevent it from getting jammed.
