GMV5 INDOOR UNIT SERVICE MANUAL
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. The
wired controller only displays the static
pressure levels matched with the identified
IDU type.
2) When the HBS network consists of IDUs
with both five and nine static pressure
05
levels, the wired controller displays nine
adjustable static pressure levels according
to the maximum control principle. If the
static pressure levels received by the IDU
from the wired controller, remote controller,
or remote monitoring system exceed the
setting range, the limit value prevails.
3)During power-on and synchronization,
the setting value of static pressure levels is
determined by settings of the IDU.
00
00
This setting is valid only when the timer
00
function is set to time-point timing.
