Economic DHW Heating
• DHW heating only by the heat pump to save energy. Target DHW temperature is lower than the temperature set by user.
The temperature di erence is de ned 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 o ".
• 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.
• 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 applying to this logic, SAMSUNG controller come to get "Thermo o " condition for all operation.
• If not used for a long time, anti-freeze uid shall be used for preventing damage to the unit in cold condition.
Maintaining the unit
Maintenance activities
• In order to ensure optimal availability of the unit, a number of checks and inspections on the unit and the eld wiring have
to be carried out at regular intervals, preferably yearly.
This maintenance should be carried out by 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.
WARNING
• Switching o the power supply stops the automatic repetitive movement of the motor in order to prevent it
from getting jammed.
