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.
