2. Set the left Ratary switch for HR unit.(Rotary switch No. "0" ‘ HR unit

No. "1")

3. Set the right Ratary switch for IDU unit.(Rotary switch No. "0" ‘ HR

unit branch No. "1")

4. Display the Master IDU No. of the HR unit on 7segment.(Default

display is "00" on 7segment)

5. Press the black button.(The IDU No. increase every 1 second in the

Identiﬁcation of Manual Valve ID (Address)

Example of checking valve address

(In case that an indoor unit of central control address "11" is connected
to a valve #1 of an HR unit)

- 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" 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 7 per a port(rotary switch 0~6), in case of

setting above of 7 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.

7. The rotary switch set value of above number of indoor units which is

connected with FF and prevents 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 with FF set)
- Prerequisite for manual valve addressing: central control address of

each indoor unit must be preset differently at its wired remote con-
trol.
