Operating Modes - Siemens RWC32/82 Guia De Instalacion

en english
Application
The POLYGYR-Ace controlller is used for the control of packaged airconditioning units or heating plant.
Two adigital outputs selectable between 2 stages of on/off control or as a single 3 point controller.
A digital relay contact input is used to select either day/night or summer/winter switch-over as determined by the setting of
the corresponding parameter.
The second analogue input can be used for the following applications:
•
PI Limiter
•
Remote Set point
•
Temperature differential
•
Temperature shift
The setting of the parameters are displayed on the LCD.
The RWC32/RWC82 controller is intended for either DIN rail mounting in a switchboard or screw mounting for external use.

Operating Modes

T he POLYGYR-Ace has three different operating modes:
•
Setup mode: Used to configure the controller to the application. In this mode the controller is not in operation.
To get into setup mode: Press „Select"
process.
•
Test mode: Used to test the functioning of the controller and the installation. The controller operate normally, but
displays the following test values:
Output 1< > Output 2< > Analog Input 1< >
Analog Input 2 < > Digital Input.
To get into test mode: Press „Up"
•
Normal mode: As soon as the configuration has been finished, the controller goes into the normal operating mode.
Time-out
From any of the described modes the controller times out back to the normal operating mode.
