Water Law for Cooling
• Outdoor air temperature range : Lower limit C1(#2051, Default 30˚C, Range : 25 ~ 35˚C),
- With this default settings, the water outlet temperature by cooling water law can be changed within the outdoor
temperature range of 30 ~ 40˚C.
• Water out temperature range for oor/FCU applications respectively :
Upper limit C1(#2061/2071, Default 25/18˚C), Lower limit C2(#2062/2072, Default 18/5˚C)
- With this default settings, the water outlet temperature by cooling water law can be changed within the range of 5/18
~ 18/25˚C.
• Type of water law for according to cooling devices( oor/FCU) : #2081(Default "1"(WL1 for oor), "2"(WL2 for FCU or radiator)
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 o only by the thermostat.
- If set to #2091/#2092 2, the compressor can be turned on or o 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 de ned 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, oor valve should be connected to zone #1 and the FCU valve should be separately
connected to zone #2 of the CONTROL KIT PBA.
• When only oor 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 oor and FCU units are installed together and operating in cooling mode, oor valve may close and E911 may
occur to prevent oor condensation when the outlet water temperature is below 16°C. Therefore FCU should secure
minimum value for the ow 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 oor condensations which can occur by not connecting the valve to
the zone #1 port of the CONTROL KIT PBA.
Upper limit C2(#2052, Default 40˚C, Range : 35 ~ 45˚C)
