Flow chart of manual addressing for pipe detection
Completion of manual pipe detection
Reset the power of HR unit PCB.
Enter the central control address into
each indoor unit using its wired remote
control.
On the HR unit PCB, manually set address
of each valve of the HR unit to the central
control address of the indoor unit
connected to the valve.
Reset the power of outdoor unit PCB.
Wait for about 5 minutes.
The number of the indoor units installed is
displayed.

Example of manual valve addressing (Non-
Zoning setting)
(In case that an indoor unit of central control address "11" is connected
to a valve #1 of an HR unit)
- Prerequisite for manual valve addressing: central control address of
each indoor unit must be preset differently at its wired remote con-
trol.
- Above setup must be done for all HR unit valves.
- The valve that is not connected with any indoor unit should be ad-
dressed with any other number than used address numbers of the
valves connected with indoor units.
(The valves does not work if the address numbers are same.)
Example of manual valve addressing (Zoning
setting)
(In case that an indoor unit of central control address “11”, “12” is
connected to a valve #1 of an HR unit)
Zoning control is connecting 2 or more indoor units at one pipe of HR
unit. In case of Zoning control, in order to set controls with multiple in-
door units connection uses the rotary switch. Namely, only the rotary
switch changes from same valve set condition and set indoor units
connection.
1) On dip switch of the corresponding valves and sets the rotary
switch at 0.
2) Setting the number with tact switch.
3) In case of addition of indoor units to same port, increases 1 with the
rotary switch and sets number with tact switch.
4) In case of checking the number which the corresponding valve is
stored, turn on dip switch and set the number of rotary switch.
5) Indoor units set available 8 per a port(rotary switch 0~7), in case of
setting above of 8 with rotary switch, it will display error.
6) Setting the rotary switch on original condition(HR unit number set
conditions) after all finishing a piping setting.
