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. 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). The controller must be mounted on a flat wall and in compliance with local regulations. 4/8 Siemens Building Technologies HVAC Products Room temperature controllers CE1N3031en 24. 09. 2003 If there are thermostatic radiator valves in the reference room, they must be set to their fully open position.
