User Parameter Settings - Gree FGR25Pd/DNa-X Service Manual

Note:
In parameter query status, "FAN", "TIMER", "SLEEP", and "SWING" are invalid. By pressing the
"ON/OFF" button, users can return to the main interface but not power on/off the unit.

3.2 User Parameter Settings

User parameters can be set in power-on or power-off status.
(1) Press and hold the "FUNCTION" button for five seconds. The temperature area displays "C00".
Press and hold the "FUNCTION" button for another five seconds to enter the wired controller
parameter setting interface. The temperature area displays "P00".
(2) Select a parameter code by pressing " " or " ". Press the "MODE" button to switch to parameter
value settings. The parameter value blinks. Adjust the parameter value by pressing " " or " " and
then press the "ENTER/CANCEL" button to complete settings.
(3) Press the "ENTER/CANCEL" button to return to the upper-level menu till quitting parameter
settings.
(4) The user parameter setting list is as follows:

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
01
of the wired controller is disabled, 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 IDU, the two wired controllers
should use different addresses. The slave
01
wired controller (address: 02) does not have
the unit parameter setting function except its
own address settings.
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
