Example of manual valve addressing (Zoning setting)

(In case that an indoor unit of central control address "11" 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 indoor 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 pip-
ing setting.
7) The rotary switch set value of above number of indoor units which is connected with FF and pre-
vents a malfunction.
(Example: The case where 3 indoor units is connected in piping 1, sets from rotary switch 0,1,2 and
3,4,5,6,7 with FF set)
- Prerequisite for manual valve addressing: central control address of each indoor unit must be pre-
set differently at its wired remote control.

- Above setup must be done for all HR unit valves.
- The valve that is not connected with any indoor unit should be addressed with any other num-
ber than used address numbers of the valves connected with indoor units.(The valves does not
work if the address numbers are same.)
