- Page 7 Starting point of optimum start control Control REA23.03RF is a 2-position controller providing PID mode. The room temperature is controlled by the cyclic switching of an actuating device. The controller generates the positioning signals depending on the deviation of the set- point from the actual value acquired by the built-in temperature sensor.
- Page 8 Mechanical design Controller The REA23.03RF has a plastic housing with a large display and easily accessible op- erating elements. The controller is removed from its base by sliding it upward. It is thus possible to replace the two type AA 1.5 V alkaline batteries contained in the compart- ment at the rear of the controller.
