19.4.2 Power-on/off
When the wired controller is unlocked and the unit is on, "ON/OFF" can be pressed to power off the unit
under the home page only; when the unit is off, press "ON/OFF" to power on the unit. The mode can be
switched under the power-off mode only.
19.4.3 Query Operation
Press the "MENU" button to enter the query interface below:
The user first uses the "▼" and "▲" buttons to select the address of module to view (the offline address is
skipped automatically). Press the "OK" button to access the lower-layer submenu, or press "BACK" to go
back to the previous interface. During operation on the menu page, press "BACK" to go back to the previous
interface. After 0# main unit is selected, the system enters the main unit operating status: operation state,
running mode, total outlet water temperature, outlet water temperature, inlet water temperature, anti-free
temperature, ambient temperature, compressor current, EXV opening degree, error code. Press the "◄"
and "►" buttons to switch the interface display.
19.4.4 Setting Wired Controller Address
Press the "MENU","►","▲" and "▼" buttons for 3s at the same time to access wired controller address
selection, and press the "▲" and "▼" buttons to select the desired values. The set address range is 0 to 15.
19.4.5 Power Failure Memory Function
The power supply to the system fails unexpectedly during operation. When the system is powered on again,
the wired controller continues to operate according to the status before the last power failure, including the
power-on/off status, mode, set temperature, failure, protection, wired controller address, timer, hysteresis,
etc. However, the memorized content must be the content set at least 7s before the power failure.
19.4.6 Combination Function of Wired Controller
1) A maximum of 16 wired controllers can be connected in parallel, and the address can be set in the
range of 0 to 15.
2) After wired controllers are connected in parallel, wired controllers with the same address are not
allowed on the bus; otherwise a communication failure will occur.
3) After multiple wired controllers are connected in parallel, data is shared among them, e.g., the
power-on/off function, data settings (such as the water temperature and hysteresis) and other parameters
