i) Unoccupied Mode
If the dry contact is closed, the Unoccupied mode is activated and vice versa. When Timer On is active,
system goes back to Occupied mode.
The dry contact connection points can be connected parallel with other fan coil unit (FCU) boards. If the
dry contact is closed, Unoccupied mode will be activated on all fan coil units that are connected parallel as
shown in figure below.

Application Information

ii) Anti Freeze Mode

Anti Freeze operation has the highest priority among all unit operation. Anti Freeze operation will be
activated only if dry contact is closed and vice versa.
iii) Window Open Mode
The dry contact connection points can be connected in parallel with other fan coil unit (FCU) boards. If the
dry contact is closed, Window open mode will be activated on all the fan coil units which are connected in
parallel as shown in figure below.
iv) Load Shedding
The dry contact connection points can be connected in parallel with other fan coil unit (FCU) boards. If the
dry contact is closed, Load shedding mode will be activated on all the fan coil units which are connected in
parallel as shown in figure below.

Global Unoccupied, Global Window Open and Global Load Shedding operation could also be activated via the
network communication bus line by master controller with or without the above connection.
NOTE :
i) Auto Fan Mode is only applicable in Model 3 only. (Cooling only with Boiler)
ii) Fan mode is not available in valveless control.
iii) Wired handset has an indoor room sensor. Avoid locating the wired handset at isolated places where room
temperature reading will be inaccurate.
