Value of #2093
– If set to #2093: 1, the compressor can be turned on or off only by room temperature sensor.
– If set to #2093: 2~4, the compressor can be turned on or off by room temperature sensor or according to the WL
discharged water temperature.
(#2093: 2, WL Thermo off → Water pump off, #2093: 3, WL Thermo off → Water pump on, #2093: 4, WL Thermo off →
Water pump 7min off → 3min on →.......)
NOTE
• Types of WL 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 as a zone controller, the zone pumps can be connected to the 2-way
valve terminals for respectively zone1 and zone2. Make sure to set FSV #4061=1, to enable zone control.
• To protect zone1 (underfloor heating) against too low water temperatures (<16°C) entering the floor
during cooling mode, the 2-way valve or zone1 pump can block the flow. This might lead to an E911 error
occurrence.
• 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.
• Zone2 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 tank integrated hydro unit PBA.
