Mechanical design Plastic casing with an easy-to-read display, easily accessible operating elements and removable cover. The removable battery compartment allows straightforward replacement of the two 1.5 V alkaline batteries. The base plate can be fitted to all commercially available recessed conduit boxes or directly on the wall and can then be wired before fitting the controller to it. The casing accommodates the electronics with the DIP switch.

The function can be selected with the DIP switch. Control The REV11… is a two-position controller providing PID control. The room temperature is controlled through the cyclic switching of a regulating unit.

Notes • • The room temperature controller should be fitted in the main living room. The place of installation should be chosen so that the sensor can capture the room temperature as accurately as possible, without being affected by direct solar radiation or other heating or cooling sources. Mounting height is approx. 1.5 m above the floor. The unit can be fitted to most commercially available recessed conduit boxes or directly on the wall.
