The DIP switch is located at the rear of the housing. 3031Z01 3/8 Siemens Building Technologies HVAC Products Room temperature controllers CE1N3031en 24. 09. 2003 Legend 1 2 3 4 5 6 7 8 Display of the room temperature, setpoints or operating mode changeover time symbol when actual room temperature is displayed Normal operation Energy saving mode symbol when displaying the operating mode changeover time or when the operating mode changeover function is activated heating on symbol indicating that batteries need to be replaced (only with battery-powered versions) Buttons for adjusting the setpoint and the operating mode changeover time Button for operating mode changeover "Normal operation energy saving mode" 9 Button for adjusting the operating mode changeover time 10 Battery compartment (only with battery-powered versions) The required room temperature setpoints for normal operation and energy saving mode and the operating mode changeover time are adjusted with buttons. Operating mode changeover can be triggered by pressing a button. The operating action for the automatic operating mode changeover function is selected with a DIP switch. DIP switch no. 1 Meaning Operating action of automatic operating mode changeover Position ON Automatic operating mode changeover from normal operation to energy saving mode or OFF Position OFF Automatic operating mode change over from energy saving mode or OFF to normal operation Notes The room temperature controller should be mounted in a location where the air temperature can be measured as accurately as possible without getting adversely affected by direct solar radiation or other heat or refrigeration sources. Mounting height is about 1. 5 m above the floor. The unit can be fitted to a recessed conduit box. · · Only authorised staff may open the controller. The cables used must satisfy the insulation requirements with regard to mains potential Mounting, installation and commissioning When mounting the unit, fix the baseplate first. Then, make the electrical connections and fit and secure the cover (also refer to Mounting Instructions).
