Fig.52 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. 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 for 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. 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.
Below are user’s parameter settings:

When 2 wired controllers control one
or more IDUs, they should have
different addresses. Slave wired
controller (02) can’t set up units’
parameters except its own address.
Communication connection between duct type IDU and light board receiver
When the duct type IDU needs to be connected to light board remote receiver, it can be connected via Dsp1 and Dsp2
on the IDU main board.
