Instructions for use:

A short press of the SET button flashes the set temperature, set the desired temperature with the SET (up) or ° C / F (down) button.
Each press changes the temperature by 0.1 ° C, a long press allows for an accelerated change.
The parameters are saved within 5 s (the display stops flashing).

A long press of the SET button allows the selection of parameters P0 ~ P8.
Simultaneous very short press (0.5s) of the SET and ° C / F buttons flashes at the bottom of the value setting display. After 5 s, the values ​​are saved and the tetmostat switches to operating mode.

P0 - mode selection, C (cooling), H (heating), factory setting = C
P1 - hysteresis, 0.1 ° C ~ 30 ° C
P2 - upper temperature setting limit, factory 110 ° C
P3 - lower limit of set temperature, factory -50 ° C
P4 - ambient temperature calibration -10.0 ° C ~ 10.0 ° C, factory 0 ° C
P5 - nothing
P6 - On / Off, factory Off
P7 - Celsius / Fahrenheit, factory ° C
P8 - factory setting, On / Off, factory Off
The saved parameters are retained even after the power is switched off!

The product is not a self-functional unit, it requires professional assembly.
