 - 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.
 - 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.
