temperature ranges. The manufacturer enters all settings of temperature regulators required for normal
functioning of the equipment. Before primary actuation the user should control and possibly set the required
temperature inside the equipment on the control panel.

It is forbidden to interfere with systemic parameters of the thermostat, as this can
lead to serious consequences, including the damage of the cooling unit!
