Treatment unit for the intensive care unit

A treatment unit with at least two heat sources and a lying surface (4) for a patient (2) is provided such that the ratio of the heat outputs of the heat sources in relation to one another can be set in a simple manner. A heater (5) with a first temperature control circuit (9) for setting a predetermined temperature on or in the environment of the patient (2) is provided along with a heater (3) at the lying surface (4). A second temperature control circuit (12) is provided for the lying surface heater (3). A logic circuit (15) is operatively connected between the first temperature control circuit (9) and the second temperature control circuit (12), which receives the temperature actual value or the temperature set point of the first control circuit (9) as a command variable and sends a tracking value as a lying surface temperature set point to the second temperature control circuit (12) via a temperature logic function (17).
