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“
for more than 5 seconds. See next pages for explanations of the setup
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“
and „Down“
key simultaneously.
•
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.
From setup-mode: after 30 secondes
From test-mode: after 5 minutes
