Default
Value
After the IDU connected
with the current wired controller is
00
successfully set to master IDU, "MASTER"
on the wired controller is on.
This setting can only be enabled through
the master wired controller.
When the infrared remote receiving
function of the wired controller is disabled,
01
neither the master nor slave wired
controller can receive remote signals. The
wired controllers can only be operated by
pressing.
When two wired controllers simultaneously
control one or more IDUs, the two wired
controllers should use different addresses.
01
The slave wired controller (address: 02)
does not have the unit parameter setting
function except its own address settings.
This value is set based on the number of
connected IDUs.
01 If the current value is inconsistent with the
actual number of group-controlled IDUs, an
―L9‖ fault may occur.
After identifying the IDU type, the wired
controller only displays the available static
pressure levels.
①. The static pressure levels fall into five
levels and nine levels for VRF IDUs.
Wired controller can be adapted to the
different types of indoor units that it
possesses 1-9 level selection for
setting static pressure.If the static
05
pressure levels received by the IDU
from the wired controller, remote
controller, or remote monitoring
system exceed the setting range, the
limit value prevails.
②. During power-on and synchronization,
the setting value of static pressure
levels is determined by settings of the
IDU.
00 Only applicable to cassette units
00
This setting is valid only when the timer
00
function is set to time-point timing.
