Water Law for Cooling
•Outdoor air temperature range : Lower limit ➀(#2051, Default 30˚C, Range : 25 ~ 35˚C), Upper limit ➁(#2052, Default 40˚C, Range : 35 ~ 45˚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 floor/FCU applications respectively :
Upper limit ➀(#2061/2071, Default 25/18˚C, Range : 18 ~ 25˚C), Lower limit ➁(#2062/2072,
Default 18/5˚C, Range : 5 ~ 18˚C)
-With this default settings, the water outlet temperature by cooling water law can be changed within the range of 18/5 ~ 25/18˚C.
•Type of water law for according to cooling devices(floor/FCU) : #2081(Default “1”(WL1 for floor), “2”(WL2 for FCU or radiator)
•The #1 DIP switch in the wired remote controller should be set to “OFF”(Default) for cooling operation of heat pump.
•The #2 DIP switch in the wired remote controller should be set to “OFF”(Default) to control the water outlet temperature.
•Only heating WL operation could be used through “Auto” mode of wired remote controller.
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.
-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
