Firstly thanks for using our instrument. This product is a
control system especially developed for the machine integrated
with refrigeration and heating for seafood pool. It is an automa-
tic change of refrigeration and heating and defrosting function.
Our sensor is especially precisely made and sealed; it is
moisture-proof , therefore its performances are more stable and
reliable.
1. Setting of Control Temperature: Slightly press to display
control temperature and light 2 and light 3 will flash. Press or
to change control temperature.
2. Parameter Setting: Hold for six seconds to enter setting
process and the indicator light will flash. Press each time for
the change of function. Press or to change the parameters
for each function. The modified parameter will be automatically
memorized.
The sensor is stalled 5 to 10cm away.
