Connection 2: Same power supply for load.
Key Instruction
S: Set key, Confirm the setting value, Entry and Set parameter. power on/off, or quit the setting.
Increase Value
Work: Output Indicator
Decrease Value
Set: Setting Indicator
Key Operation Instruction
- In normal working status, hold power button for 3 seconds to power off, hold same button for 3 seconds to power on.
- In normal working status, press S. The led flash. Press UP or down 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 UP + DOWN to switch from HC-A7. Press S to enter any code, press UP + DOWN to change code setting.
- Both press UP + DOWN for 3 seconds to rest the controller.
Operation Instruction
-
In normal working status, the screen display RT (real time temperature value).
-
Cooling 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, set10℃, difference 3℃, cooler work when RT≥13℃. Cooler stop when RT≤10℃. -
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℃.
