Use Instructions

1. Connect the power supply in the input terminal and the load in the output terminal.

2. After powering on, the screen will display the real-time temperature. Press the SET key to set the stopping temperature, using UP/DOWN buttons. After you adjust the desired temperature, confirm it by pressing the RST key.

3. Press and hold for about 5 seconds the SET key to enter in the internal functions menu. If you want to restore to the factory settings, press and hold both UP and DOWN buttons.

Internal functions menu

P0 cooling and heating mode

High temperature start for cooling mode, please set to C

Low temperature start for heating mode, please set to H

P1 hysteresis setting

In heating mode (H): measured value ≤ set value - start output heating to set value stop when returning

In cooling mode (C), when the measured value ≥ set value + hysteresis, the output cooling is started to the set value stop.

P2 limits the maximum setting (non-temperature setting)

P3 defines the lowest set value (non-temperature control setting)

P4 temperature correction

When the measured temperature deviates from the standard temperature, this function can be used to correct the corrected temperature = temperature before correction + correction value

P5 delay start time

When controlling the cooling of the compressor equipment, the delay time can be set as needed. When the controller outputs, the equipment will not start immediately, and it needs to start after the set delay time.

P6 high temperature alarm

When the measured value is greater than this value, the screen is displayed -- and the sound alarm is dropped. Simultaneously disconnect the output

P7 data lock function

Turn on the data lock to keep the current settings from being changed. At this time, the setting temperature and function are invalid. If you need to modify it, you need to turn off the data frequency function.

P8 factory reset

Long press SET to switch to P8, press SET to set to on, press RST to restore factory settings. You can also press and hold the + - button to disable the POST and restore to the factory settings
