Auto-restart 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.
7.2.6
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 will be kept consistent (note: The mode,
temperature, and hysteresis settings can be shared only when the system is powered on)
4) Start point of data sharing: After the power-on/off button is pressed, data can be shared during parameter adjustment.
The "OK" button must be pressed after parameters are adjusted, and the finally adjusted values will be shared.
5) Since the bus is processed in the polling mode, the data of the wired controller with the minimum number is valid if
multiple wired controllers are operated at the same time in the same bus cycle (4s). Avoid the above situation during
operation.
6) After any of parallel wired controllers has been reset, the address of this wired controller is 0 by default.

Monitoring setting of wired controller
Press the "MENU" and "
►
" buttons for 3s at the same time to access "SET ADDRESS" interface, The interface display is as
follows.

button the setting is saved automatically, and the system returns to the home page. Press the "BACK" button to cancel the
setting and return to the previous interface. The units only have one main control wired controller (the default address
00),and other address(address 01-15)must be set as monitor wired controller. When set address "00" and press "OK"
button, the wired controller will enter the interface as follows.
