Programming :

Once connected, to be able to configure it, you must hold the left button for a few seconds. Then with the middle and right button Modified the setting with the lettre “H” (heater) by “C” (cooling). For the other setting I stay on P0. Personally I set the thermostat at 32 °C. This has the effect that the exhaust fans turn on when the temperature reaches 34 °C and cuts when it drops to 30 °C.
