3.7 Power
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.
3.8 Parallel 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).
Failure Memory
4) Start point of data sharing: After the
power-on/off button is pressed, data can be
shared during parameter adjustment. The
"OK" button
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.
