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.
