Engineering inquiry and setting of hydro box
The setting is the same as inquiry and setting for engineering No. of indoor unit, as below:
1. Engineering No. inquiry of a single indoor unit
Press and hold the ―Function‖ button for five seconds in power-on or power-off status to enter
into parameter inquiry interface ―C00‖. The timer area of wired controller will display the
engineering No. of the current indoor unit. If the current wired controller works in one-to-many
mode, the displayed indoor unit in the timer area is the unit with the minimum project No.;
2. Inquiry for engineering No. of multiple indoor units
① Engineering No. inquiry of indoor units in one-to-many mode: press and hold the ―Function‖
button for five seconds in power-on or power-off status to enter into parameter inquiry interface
―C00‖. Press ―▽‖ to switch to ―C01‖, and then press the ―Mode‖ button to enter to inquiry. The timer
area displays engineering No. of indoor unit from small to large. Press ―△‖ or ―▽‖ to switch
engineering number.
Notes: It is normal if the buzzer of the indoor uni operated by the wired controller rings. The
purpose of ringing the buzzer is to facilitate engineering commissioning personnel to locate the
indoor unit, especially for the indoor unit without any LED panel because it cannot display its
engineering number.
② Engineering number inquiry of indoor units in the entire communication network: Press
and hold ―Function‖ button for five seconds in power-on or power-off status to enter into parameter
inquiry interface ―C00‖. Press ―▽‖ button to switch to ―C18‖, and then press ―Mode‖ button to enter
