Use Instructions

Press and hold the SET button for about 3 seconds to enter in the internal functions menu. Select the parameter you want to set, using the UP/DOWN buttons, according to the below table. Press again the SET button and you can change now the value of the selected parameter, using UP/DOWN buttons. The settings you have made will automatically save. To set the start and the stop temperature, you just have to use the UP/DOWN buttons, when the controller is in the initial state.

Function menu

P0 Working mode: if the thermostat is used for heating, the parameter is set to H; if the thermostat is used for cooling, the parameter is set to C

P1 hysteresis value setting: 

The difference between the temperature at which the thermostat switches off and the temperature at which it switches on again is the hysteresis. Now, you set a temperature of 72 – your thermostat will let the temperature rise in your house until it is 73 or 74 degrees, then cool it down to 71 degrees, and allow your system (and your energy bill) to relax for a bit, saving you wear and tear on your system.

P2 temperature correction: when the measured temperature deviates from the real value, it can be corrected with this function

Corrected temperature = Temperature before correction + Correction value

P3 delay start:

This function is used for compressor refrigeration. If you buy this thermostat for the fridge freezer, then this value must be set according to the pressure of the compressor. The general setting is 3-6 minutes.
