Siemens Building Technologies Room Temperature Controller CE1N3042en
HVAC Products 22.08.2003
A changeover switch can be connected to status input D1-GND. When the switch
closes its contact (caused by an open window, for instance), the operating mode will
change from normal operation to energy saving mode (provided DIP switch no. 1 is set
to ON), or from normal operation to OFF (provided DIP switch no. 1 is set to OFF).
Ordering
When ordering, please give name and type reference.
The QAH11.1 temperature sensor (can be used as a changeover sensor), the
changeover mounting kit and the valve and air damper actuators are to be ordered as
separate items.

Mechanical design
The unit consists of two parts:
• A plastic housing which accommodates the electronics, the operating elements and
the built-in room temperature sensor
• A mounting base
The housing engages in the mounting base and snaps on.
The base carries the screw terminals. The DIP switches are located at the rear of the
unit.
