Programming The MSR eco parameters are simple to access, view and change. During normal operation, or if no key is pressed for at least 3 minutes, the MSR eco will display the following: 1st priority: current failure display (blinking) 2nd priority: operation status display (ex. „oFF“) 3rd priority: selected „permanent parameter“ display Selecting and Changing of Parameters Key Action P (> 2 sec.) ....Page name will be displayed .................Select desired page P ..................Enter the page .................Select parameter P ..................Prepare programming.

They are divided into 3 groups or levels with 3 operator codes. An access code will be required to change an adjustable parameter, (see parameter listing).To change an adjustable parameter that requires an access code, begin by pressing the „P“ key.: The screen will display C00, prompting the user for access code entry. The Access Codes are divided into 3 access levels, (OEM, Technician, and Customer Codes). - OEM Code „oem“: Month + Hour + 20 The OEM Code grants access to all adjustable parameters on the device. - Technician Code „tec“ : 88 TheTechnician Code grants access only to „Technician“ and „Customer“ assigned adjustable parameters. - Customer Code „---“ : no access code required. The Customer Code grants access only to „Customer“ assigned adjustable parameters. If no key has been pressed for 3 minutes, the operator code must be re-entered. (00 Parameter Pages P (L) > 2 sec.

Configuration Concept
Theinputs/outputsoftheMSRecoStageControllerhavenofixedfunctions.TheMSRecoworkswithan"open configuration"concept.Thismeansthatallavailableinputsandoutputs(relays, sensors, digital inputs, analogue output)canbeconfiguredtoworkwithanyavailablecontrolfunctionorcontrolcircuit.Temperature SensorsSensorscanbeusedtocontrol,orsimplytodisplay.Digital inputs (DI, Optocoupler inputs)Each digital input can be assigned to one of thepossiblefunctions.Relay OutputsEachrelaycanbeusedtocontroloneofthepossiblefunctionsandcanalsobeswitchedonmanually.
The relay outputs #2, #3 and #5 are Solid State Relays (SSR) with a lower contact rating than the standard relay outputs. They can be used for any function within the specified current range.
