The REPEAT key will re-scroll thecurrent display from the beginning. When scrollingthe display or programming with the remote, it isessential to wait until the display has completelyfinished scrolling and is at rest before makingentries. The Degree Master will not respond toentries made while the display is scrolling.The VIEW keysSTATUSThe [STATUS] key will first display the wordsCASE STATUS, then the default temperature. Thedefault temperature can be programmed to beCTRL TEMP (a circuit control setting provided bythe network manager), CASE TEMP (a temperaturevalue from a sensor in the case), or PRODTEMP (a value provided by a product temperaturesensor in the case). By using the down arrow, theother two fixtures temperatures will be displayed inthe order programmed.Here are all of the status displays in the orderthat they will appear using the down arrow, andtheir meanings:MAX PROD TEMPthe highest temperature reached since midnightor the last resetALRM STATcurrent alarm conditions for the fixtureNO AL there are no active alarmsHI T there is a high temperature alarmLO T there is a low temperature alarmDCHdischarge air temperatureRTNreturn air temperatureDEFR TERMthe temperature at the defrost termination sensorEVAP INthe temperature of the evaporator at its inletEVAP OUTthe temperature of the evaporator at its outletSUPR HEATthe evaporator superheat, calculated as thedifference between the EVAP OUT and EVAP INsensors.LOADSThe [LOADS] key reveals data for the DegreeMaster’s controlled loads (outputs). Each of the14
loads can have one of two states -- ON or OFF.Here are the displays in the order that they willappear after pressing the [LOADS] key on theremote:REFRthe status of the refrigeration output; whether theDegree Master is calling for refrigeration to beon or off.DEFRwhether the fixture defrost output is on or off.FANwhether the fixture fan output is on or off.LGHTwhether the fixture light output is on or off.ASHthe percentage of time the anti-sweat heaters areon. NOTE: the % sign is represented by a P. Thisvalue will read 100P if there is no ASH modulepresent.REFR OVRDwhether or not refrigeration control is in override.If you push [ENTER] while in this field,you can select override of DEGREE MASTERcontrol by scrolling down from “NONE” to“ON” or “OFF” and pushing [ENTER] again.DEFR OVRDwhether or not defrost control is in override.

It alsovaries with the version of software installed. Hereare the displays in the order that they will appearafter pressing the MISC key on the remote:DEWP TEMPthe calculated dew point temperature receivedfrom the network manager.SUCT TEMPsuction temperature received from the networkmanager.DOWthe day of the week received from the networkmanager.TIMEthe time of day received from the networkmanager.SUBNthe subnet address (used by Degree Masterservice technicians).NODEthe node number of the particular DegreeMaster on the network.VERSIONthe version number of the Degree Mastersoftware installed.15
