Use instructions

1. Choose the working mode:

Press and hold for about 3 seconds the SET button and the screen will display P0 parameter, then press shortly SET again to modify the PO value: H is for heating mode and C is for cooling mode.

2. Set the hysteresis value:

• 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.

3. Set the stop temperature:

After the working mode and the hysteresis value were set, press the ENT button to confirm and the screen will display the real-time temperature. Press shortly the SET button and the display will flash. You can now set the stop temperature using UP/DOWN buttons

If you want to modify another parameter, you have to enter in the internal settings by pressing and holding the SET button and with UP/DOWN buttons you can navigate between the parameters.

Parameters menu table

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 ENT to restore factory settings.

You can also press and hold the + - button to disable the POST and restore the factory settings
