5. Key Operation Instruction

•
In normal working status, hold
hold 3seconds to power on.
•
In normal working status, press S. The led flash.Press
or
to increase or decrease the setting temperature
value. Press S to save it and back to normal screen.
•
In normal working status, press S for 3s to enter set mode.
Press to switch from HC-A7.(see menu code). Press
S to enter any code,press

•
Both press

6. Operation Instruction

•
In normal working status, the screen display RT(real time
temperature value).
•
①Cooling mode: HC set to C. use cooler as load. When
RT ≥ ST (temperature set value) + D (difference value),
work indicator turn on. output relay connect. Load start to
work. When RT ≤ ST, work indicator turn off, output
relay disconnect, load stop working.
• For example,set 10 ℃ ,difference 3 ℃ ,cooler work when
RT≥13℃.cooler stop when RT≤10℃.
• ② Heating mode: HC set to H,use heater as load. When
RT≤ST-D, work indicator turn on. output relay connect.
load start to work. When RT≥ST, work indicator turn off,
output relay disconnect, load stop working.
•
For example,set 10 ℃ ,difference 3 ℃ ,heater work when
RT≤7℃.heater stop when RT≥10℃.
