4.1. Temperature regulation
The thermostat is to obtain the set temperature within the equipment and maintain it within the determined
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.
Digital display – displays the current temperature inside the equipment.
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!
