A thermal control unit comprising: a first fluid outlet adapted to fluidly couple to a first fluid supply line; a second fluid outlet adapted to fluidly couple to a second fluid supply line; a first fluid inlet adapted to fluidly couple to a first fluid return line; a second fluid inlet adapted to fluidly couple to a second fluid return line; a heat exchanger; a pump for circulating fluid from the first and second fluid inlets through the heat exchanger and to the first and second fluid outlets; a sensing subsystem (76a, 76b) adapted to detect if the first fluid outlet becomes disconnected from the first fluid supply line and if the second fluid outlet becomes disconnected from the second fluid supply line, the sensing subsystem (76a, 76b) including a first flow meter adapted to measure a first flow rate of the fluid through the first fluid outlet and a second flow meter adapted to measure a second flow rate of the fluid through the second fluid outlet; and a controller in communication with the pump, the heat exchanger, and the sensing subsystem (76a, 76b); characterized by the controller being adapted to provide a first indication to a user if the first fluid outlet becomes disconnected from the first fluid supply line and to provide a second indication to the user if the second fluid outlet becomes disconnected from the second fluid supply line, wherein the controller is adapted to provide the first indication if the first flow rate measured by the first flow meter decreases below a threshold and to provide the second indication if the second flow rate measured by the second flow meter decreases below the threshold. a first fluid outlet adapted to fluidly couple to a first fluid supply line; a second fluid outlet adapted to fluidly couple to a second fluid supply line; a first fluid inlet adapted to fluidly couple to a first fluid return line; a second fluid inlet adapted to fluidly couple to a second fluid return line; a heat exchanger; a pump for circulating fluid from the first and second fluid inlets through the heat exchanger and to the first and second fluid outlets; a sensing subsystem (76a, 76b) adapted to detect if the first fluid outlet becomes disconnected from the first fluid supply line and if the second fluid outlet becomes disconnected from the second fluid supply line, the sensing subsystem (76a, 76b) including a first flow meter adapted to measure a first flow rate of the fluid through the first fluid outlet and a second flow meter adapted to measure a second flow rate of the fluid through the second fluid outlet; and a controller in communication with the pump, the heat exchanger, and the sensing subsystem (76a, 76b); characterized by the controller being adapted to provide a first indication to a user if the first fluid outlet becomes disconnected from the first fluid supply line and to provide a second indication to the user if the second fluid outlet becomes disconnected from the second fluid supply line, wherein the controller is adapted to provide the first indication if the first flow rate measured by the first flow meter decreases below a threshold and to provide the second indication if the second flow rate measured by the second flow meter decreases below the threshold.
