To connect multiple indoor units to a port
-
- Maximum total capacity of connected indoor units: W(P)80 or below
-
- Maximum number of connectable indoor units: 3 units
-
- 2-Branch Joint Pipes are not supplied.
All the indoor units that are connected to the same port must be in the same group and Thermo-ON/OFF
operation simultaneously. For all the indoor units in the group, the room temperature needs to be monitored via
the connected remote controller.
-
- When connecting a W(P)71 through 125 model of indoor unit to an HBC controller, the pipes connecting the unit
to the same set of HBC controller ports cannot be branched out to connect additional units.
-
- When connecting multiple indoor units including a W(P)63 unit to the same set of HBC ports, use a size 32A pipe
in the section indicated as "b’ and c" and connect the W(P)63 unit to the pipe indicated as "c" in the figure. To the
2-Branch Joint Pipe to which a W(P)63 is connected, either a W(P)10 or a W(P)15 unit is connectable.
・
Connecting W(P)100 or 125 indoor units to an HBC controller
-
- When connecting W(P)100 or 125 indoor units to an HBC controller, connect each unit to two sets of two ports on
the HBC controller, using two Joint Pipe Kits. (See Fig. 9-4-1.)
-
- Connect an increaser (20A-to-32A) to the merged side of each Joint Pipe Kit. (See Fig. 9-4-1.)
-
- When connecting Joint Pipe Kits to HBC ports, the branched sides of the Joint Pipe Kits cannot be connected to
combinations of ports "4 and 5," "8 and 9," or "12 and 13." (See Fig. 9-4-2.)
-
- When connecting a W(P)100 or a 125 model of indoor unit to an HBC controller, the pipes connecting the unit to
the same set of HBC controller ports cannot be branched out to connect additional units.
・
Maximum connectable capacity of indoor units to HBC controller
-
- HBC controller has two pumps. Each pump can accommodate the capacity of indoor units equivalent to
W(P)175. Make sure that the total capacity of the indoor units connected to "ports 1 through 4 and 9 through 12"
or "5 through 8 and 13 through 16" will not exceed W(P)175. (See Fig. 9-4-2.)
