Siemens Building Technologies O3341(RWD32) V14c2.doc is a document about the installation and commissioning guide for this universal controller used for HVAC system comfort control. The controller can provide two digital output signals for 2-stage on/off control or as an independent three-position controller. The main analog input signal can be set to C0, F0, % or no specific unit. The second analog input signal can be used for PI limit function, remote parameter setting function, setpoint compensation, summer/winter mode conversion, cascade control function, refrigeration/dehumidification priority control, etc. The controller can be installed on a standard DIN rail inside a switch box or mounted in a protective enclosure with screws. Specific application numbers and menu display descriptions can be found in the document.
