Fig.4.7.6 Two wired controllers control multiple IDUs
When two wired controllers control multiple IDUs, the wired controller can be connected to
any one IDU, provided that the connected IDU is of the same series. Meanwhile, one and only
one of the wired controllers must be set as a slave controller. At most 16 IDUs can be
controlled by wired controllers and the connected IDUs shall be within a same IDU network.
No matter when unit is turned on or off, slave controller can be set.
How to set a slave controller: hold “function” button on the designated controller f or 5s, and
temperature zone displays C00. Continue holding “function” button for 5s and setting screen of
controller parameter will come out. Default temperature zone displays P00.
Press button or
button to select parameter code P13. Press “mode” button to
switch to setup of parameter values. Then the parameter value will blink. Press button or
button to select code 02. And then press “confirm/cancel” to finish setting.
Press “confirm/cancel” to return to the previous display until you exit from the setup of
parameter values.

set up units’ parameters except its own
address.
