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)
