room temperature and set-point exceed 1°C, FCU valve will be open; if room temperature and set-point are equal,

HL2025DA/DAE/DA2/DA2E will close the FCU valve with the fan still running, HL2025DB/DBE/DB2/DB2E will close

both of valve and Fan.

» Control FCU Valve under 4-pipe conguration (HL2025FCV2/FCV2E): In cooling, when the room temperature is

higher than set-point, the cooling Valve will be opened. Otherwise it will be closed. Heating valve is always closed.

In heating, When the room temperature is lower than set-point, the heating valve will be opened. Otherwise it will be

closed. Cooling valve is always closed.
