Field setting mode
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, the compressor can be turned on or off by the thermostat or
according to the WL discharged water temperature.
– 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.
