Wiring Diagram

Connection 1: Independent power supply for load.

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℃.
