《EW-983A Directions》
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.
Technical Specifications：
1、 Operating voltage : AC220V
2、 Load current : 5A/220V/AC
： ≤3W
3、 Power Consumption
4、 Working environment
5、Controlled Output: one for compressor and
one for four-way valve.
： ℃ ～80℃
6、 Control Range 1
：1℃
7、 Resolving Power
8、Defrosting with water and condenser uses one sensor
respectively. The standard length is 1.5m ( The maximum
extension can be 50m. The extended cable should be shielded.)

Brief on Operation
EW-983A
When light 1 is
Run at heating mode. The compressor and
always on
four-way valve work.
When light 1 is
Run at refrigeration mode. The compressor
always on
works independently.
When light 1 is
Run at defrosting mode. The compressor
always on
and four-way valve work.
Attention please:
when setting "HS", the ruler is: "HS" > ("setting-
temperature" + "d").
When setting "LS", the ruler is: "LS" > ("setting-
Temperature" － "d").
