4.3.7 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.
4.3.8 Parallel Function of Wired Controller
Parallel function by MODBUS:
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 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).
3) Start point of data sharing: After the power-on/off button is pressed, data can be shared
during parameter adjustment. The " " button must be pressed after parameters are
adjusted, and the finally adjusted values will be shared.
4) Since the bus is processed in the polling mode, the data of the wired controller which is
set last is valid if multiple wired controllers are operated at the same time in the same bus
cycle (4s). Avoid the above situation during operation.
5) After any one of parallel wired controllers has been reset, the address of this
wired defaults no address and needs to be set manually in order to enter into normal
communication.
Parallel function by XYE:
1) A maximum of 16 wired controllers can be connected in parallel
2) The wired controller need to set to control/monitor controller. The former has control
functions, while the latter has only viewing functions.
